Ubuntu Installation :: Can't Add User To Encrypted Installation
Dec 5, 2010
I just installed Ubuntu 10.04 and decided to encrypt the entire hard drive for the first time. I followed the tutorial on how to install Ubuntu and encrypt the hard drive during installation, located here: [URL]
Everything worked as planned, however, I cannot successfully add a user. Specifically, I can add a user account, but when that user logs in, they receive an error stating: "Could not update ICEauthority file /home/username/.ICEauthority". Closing this window results in a second error: "There is a problem with the configuration server. (/usr/lib/libgconf2-4/gconf-sanity-check-2 exited with status 256)". Then I get errors stating that Nautilus could not create the Desktop or .nautilus folders. After this, the computer hangs indefinitely at the desktop wall paper.
I have googled these errors and found several different solutions, none of which have worked. I have looked in the user director and there is no .ICEauthority file to change permissions on. I suspect that this has to do with the encryption I did, but an evening of looking through google has resulted in no joy.

I want to create a user with a encrypted home folder. I tried "sudo adduser --encrypt-home username" but I get following error "adduser: Could not find program named `ecryptfs-setup-private' in $PATH". I installed the cryptsetup package but without result.

Installing Debian on a new laptop and read that Debian-Installer (DI) can create an encrypted partition (/home) during installation.However, when I went through installation and started the manual partitioning (standard, non-lvm) , I am unable to locate the encryption option.

I burnt an Ubuntu Server 10.4 LTS iso to a CD and have started installing to my system: ASRock ION330, 4GB RAM, 320GB HDD. I'd be using it for web hosting, maybe mail, and programming. And possibly watching video (by HDMI into TV).
When I get up the the LVM part, I'm having trouble deciding what option to take. Some of them:
"Guided - use the entire disk and setup LVM"
"Guided - use entire and setup encrypted LVM"
"Manual"
After using google fu, I think I get the basic idea of LVM, that it abstracts the partitioning so I can change the size of them on the fly. This means I can change it later, but the installer also mentioned that once I choose something, I couldn't turn back or something, which made me panic.
Also, if I choose encrypted, how does that affect my day-to-day usage? Do I have to type in my password every time I access a file or save one? That doesn't seem right. Then what's the point of encrypting? Is encryption worth it? Google isn't telling me this sort of information (and I can't find it in help on the ubuntu website). Keep in mind that I'm really just guessing.
Given my above hardware, and usage, should I just take "Guided - use the entire disk and setup LVM"? Is encrypted a good idea?

I have XP on sda1, Fedora 11 encrypted on sdb 1 (boot) and sdb 2 (root), I would like Ubuntu on sdc 1 (boot) sdc 2 (root). However when I tried to install from the cd the partition manager does not see my Fedora as an OS (I assume because it is encrypted). So my question is how can I achieve my triple boot without having to have my Fedora unencrypted. I want it encrypted for a reason.
Also I cancelled the installation for Ubuntu and it reverted to a Live cd and I tried to mount my Fedora encrypted drive. Ubuntu asked for the pass and when I entered it I get an error saying it cannot be mounted because it is not a mountable file system. This is not good for me because I would like to be able to access all my hdd's from both distro's.

After trying out ubuntu for a while (and messing something up that required I reinstall), I installed karmic using the encrypt home directory option. Now I can't run several programs, such as Computer Janitor, SBackup, Software Sources, and Synaptic Package Manager (I can run Synaptic only if I launch it through a terminal using "sudo synaptic"). All of these programs worked flawlessly for me when I didn't have an encrypted install. I am very new to linux, the join date to the left is about when I started trying ubuntu

How can I set up an encrypted LVM without using the "Guided - Use entire disk" option of the alternate installer.
My drive is quite big and I would like to be able to have my encrypted LVM as well as an extra LUKS encrypted partition which I could mount whenever needed. Unfortunately the options in the alternate installer do not allow me to do this without using up the entire disk.

I tried upgrading to 10.04, and now when it boots it just goes into a grub2 terminal and doesn't display a boot menu. I tried re-installing grub2 from the live cd, but that didn't do anything. I figured if I've hosed the last install I'll install from scratch, but I can't even access my files from the live cd! I did a bit of searching and everyone seems to just encrypt ~/Private, whereas I've encrypted the whole home directory. So much for security... In the live cd, it has a readme.txt and says to type "ecryptfs-mount-private" to access the files, but it just gives the error "ERROR: Encrypted private directory is not setup properly". What do I do?

I purchased a larger hard drive to upgrade my HTPC running MythTV and a Samba file server. I put the old hard drive into an e-SATA enclosure and can still boot to it to access my files, but I can't seem to mount it correctly under the new installation to copy over my files even though I have the mount passphrase and encrypted filenames key.I have tried using this howto, but I run into problems with the encrypted filenames.This is how I'm doing it. I replaced the actual key data with A's and B's to protect my keys:
Code:
$ sudo -i
# ecryptfs-add-passphrase --fnek
[code].....

I'm wiping out / on an Ubuntu box but want to keep everything in /home/, which is mounted on a different partition. Using Code: ecryptfs-unwrap-passphrase ~/.ecryptfs/wrapped-passphrase I have unwrapped the passphrase, resulting in a ~25 character alphanumeric string. Is it possible for me to install from a disk and give the installer the (current) passphrase so that it will automatically mount my home directory?

I used Windows XP's encryption to encrypt some folders on an NTFS Hard Drive.Upon mounting this drive in ubuntu, I can see all folders, and all file names, but I cannot open the contents of the encrypted files, getting "Permission Denied" despite all permissions being -rwxrwxrwx.Is there a way to open these from linux? I know the Windows XP login / encryption password.

I just replaced my Fedora 14 installation in which I have an encrypted LVM which contains /home and /tmp (no, I didn't back up ), when I boot I enter my password, and get dropped to the maintainance login a few minutes later. I'm wondering how I can mount my /home from the Live system so I can just back up over the network.
I haven't worked with LVM very often so I'm out of my depths on this.
This is my partition layout as reported by the installer: screenshot
Edit: upon boot the system tells me that /dev/mapper/logvol01 and /dev/mapper/logvol00 don't exist
Edit2: Nevermind, Disk Utility is smarter than I am.

I encrypt a partition using LUKS, and store personal data on this partition. Then create a user account that solely deals with this partition and insulated from the Internet. Normally for each boot I do not even need to mount the LUKS encrypted partition, and when I mount that partition under that special user account, I can make sure that the Internet is cut off. I'm going to do the alternate installation these days, could you provide a brief sketch regarding what steps I should go through to implement the above result?

I have installed Kubuntu 10.04 x64 from scratch using the alternate installation CD and unfortunately I'm experiencing some serious troubles. Everything worked fine, installed packages, moved my backed-up data to my encrypted /home partition - until I rebooted. Usually I reboot the system right after the installation process to see if the boot process shows any errors, but what can I say, seems like I forgot to do it this time .
The problem is that the boot process just "hangs" right before the login window should disappear. By "hang" I mean dead: no switching to virtual terminals, no CTRL-ALT-DEL - the system just freezes.
I'm quite familiar with doing things shell-wise, so I started the "Rescue Mode" from the alternate CD and was able to mount my root partition.
Problem #1: No faulty log entries whatsoever: dmesg, boot.log, messages etc. all looking fine - except Xorg.0.log. I suspect the proprietary Nvidia drivers to be the culprit here, because what I'm getting is: "Caught signal 11 (Segmentation Fault). Server aborting"
Running "startx" as root from the rescue shell gives the same results: complete system freeze. "Looks like a reinstallation candidate, let's just backup my data" I thought, which brings us to
Problem #2: I can't mount my encrypted /home from the rescue shell. The exact steps involved are:
Mount my root partition and chroot to it. Issuing "ecryptfs-mount-private" gives the following error message: "ERROR: Encrypted private directory is not setup properly" Becoming my user "su - faulty" and trying step 2 again yields the same results. I feel like I'm almost there: I'm executing commands in my root environment, just can't seem to access my data which I'd like to backup before doing a clean reinstall. Any thoughts?

Alternate CD on USB - Natty not mounting Encrypted Volume I get initramfs prompt. I have a Dell Inspiron Duo. I've tried to install Natty i386 and AMD64. I set my / (root) and swap under LVM under an encrypted volume. Used manual partitioning. But after reboot, I successfully enter the passphrase, swap and root are not mounted.
Now, I've had this working with 10.10. System seemed a little quirky after the upgrading it to Natty. So, I wanted a fresh install. Used Unetbootin to run ISO from USB and also from one of my other partitions. I've tried installing at least 10 times, some repeat, some variations.

I had errors pop up when I tried updating my 10.10 to 11.04 so I ended up having to do it from a Live USB which installs it over everything (fine by me).Unfortunately I forgot I had an encrypted /home directory. So various messages and stuff came up when I tried to log in.nfortunately I don't remember what my encryption passphrase is offhand, so I moved it to a slightly different folder name and had to have a new directory created for my username.It's still there, but how can I try to open it trying the various versions of the passphrase I think it may be? Can I double-click it and try?Also, in the future what is the best way to handle a "fresh" install that I want to connect to my encrypted /home directory?

I just tried reinstalling ubuntu 11.04 from the live disc, installation went well but afterwards I cannot get access to my home directory which is encrypted and I stupidly forgot to note the mount passphrase. is there anything I can do? where would the mount passphrase be stored from the previous installation and is there any chance of recoving it. Home and the root are on the same drive and the installation did not format the drive.

I've installed Ubuntu 11.04 on a Fujitsu Esprimo E900. During installation, I've used the guided encryption setting because neither GRUB nor LILO would ever install on the LVM configurations I created myself. So after installing Ubuntu 11.04, when I boot regularly, the computer freezes completely. When I try to launch the recovery mode kernel, I get this far and then the computer locks up, too. Ubuntu lockup during boot by germanium, on Flickr
You can see the label is sdb5_crypt which is a bit odd since the partition is on /dev/sda. However, I already tried changing grub.cfg to /dev/sda instead of /dev/sdb but that didn't do anything. This is all a bit odd to be. The funny thing is I've been trying to set this computer up for a month and I'm a professional programmer (Java, JavaScript, Groovy) with 20 years of programming experience and I never thought Ubuntu would be this hard to install on a more-or-less stock Intel box.

I want to install debian 7.7 to a laptop with encrypted LVM, but some how i can't install inside the LVM a separate /home and swap partition. Graphic Installer says i cannot change anymore after i made a encrypted LVM. When i make the separate partitions before making an LVM, i can encrypt them but i have to enter for every partition my passphrase. How I can create a LVM with /, /home and swap without entering three times my passphrase.

After my NVIDIA card died I decided it was time to buy an AMD card again (R9 270X), but I didn't think AMD drivers were such a pain in Linux as people said. Of course, in some distros anyway. On Arch, for example, there's no official release because Arch's developers would have to hold Xorg in order to make a closed-source driver available, because AMD's pace isn't in pair with Linux. So in order to install AMD's drivers on Arch I must rely on some guy's unnoficial repositories, but that isn't the whole problem. Even though I'm cool with adding repos and downgrading Xorg, I'm not cool with it not working for a lot of apps, so that's where I decided to try a few distros. Manjaro is a no-go because it installs Flash as default. openSUSE although is a very good distro, is a complete mess when it comes to repositories, specially multimedia ones. Ubuntu/Mint are also a no-go, Ubuntu because after 12.04 they have a spyware by default, and Mint because it contains non-free stuff by default.
So here I come! I ran Debian in the past for a long time (aside from a breaf period last year) and it was lovely, I could easily set up a custom encrypted install, but now I don't remember how to, and it's killing me. I don't like how the installer doesn't show the partitions size as they actually are, and I don't like how the automated encrypted LVM setup doesn't let me chose the encryption algorithm or the timeframe between each passphrase attempt. That's why I must create my install, and here's what I used to do on Arch (the part that really matters), converted to what I use on Debian:
Code: Select all# modprobe dm-mod
(create one 1GB partition for /boot, unencrypted ; create another big 930 GB formatted as "8e" - LVM - on dev/sda2)
Code: Select all# fdisk /dev/sda
(chose my ciphers and iter time)
Code: Select all# cryptsetup -c twofish-xts-plain64 -y-s 512 --iter-time 5000 luksFormat /dev/sda2
(open the luks container on "sda2_crypt")
[Code].....
After this is done, I go to the "partition disks" page where I select each partition/volume to it's correct destination. I then proceed to installing the base system, configuring apt, and all that. Now, before I install Grub I used to execute the following commands on shell:
Code: Select all # nano /etc/crypttab
I used to put something there, but I don't remember what exactly. It's been a long time since I used Debian for long! But here's what I put there:
Code: Select allsda2_crypt /dev/mapper/sda2_crypt none luks
Then I procceeded to instal syslinux (I REALLY don't like GRUB)
Code: Select all# chroot /target
# apt-get install syslinux
But I get the following error:
E: cannot write log (Is /dev/pts mounted?) - posix_openpt (2: No such file or directory).

I installed an old version on accident, I used an encrypted LVM. When I removed the old debian and started the installation of the new version, the encrypted partition could not be used to install, and the drive itself was creating an error message when I tried to mount the installation there. This is probably a vague explanation of what is happening, but does anyone know how to remove these encrypted LVM partitions?

P**sed right off now, tested this upgrade on two test systems before hand to make sure this would work.Upgrade my server from FC9 to FC10, it had two Encrypted XFS volumes on totalling 1.5TB of files which I don't have space to backup anywhere else.Have now upgraded and the Encrypted volumes are showing as not existing "volume name does not exist"

I encrypted "/" and "/home" during boot with F12. Now I'm trying to install F13. The problem is it will not allow to specify /home as the mount point. It will take /home and not complain but when I get back to summary there is no mount point, just blank. When I entered the passphrase it didn't complain so I think that is okay. The / dir I said I wanted to format, so it accepted the / mount point.
I tried to go ahead and install F13 anyway thinking it may figure this out. However it didn't use my /home but created a new /home.

I was running Ubuntu 9.04 Desktop on a headless Pentium 4 machine which is our file, mail, web & fax server. The two x 250GB SATA hard disks were in a RAID 1 array with full disk encryption. Ran the 9.10 upgrade via WEBMIN and it failed. I should have known then to copy over everything to a backup disk, but instead I rebooted.
On restart the machine accepted my encryption passphrase but promptly hung with a mountall symbol lookup error - code 127. So I can't start the machine to get at the disks, and using a Live CD is useless as it has no way to open the RAID array to get at the encrypted partitions. Although we have data backed up (as at last night) I'd hoped not to have to rebuild the entire server from scratch. But its looking bad.I have taken one drive out and plugged it into another machine (Hercules), and the partitions show up as /dev/sdb1 /dev/sdb2 /dev/sdb3.
If it weren't for RAID, I could open /dev/sdb2 the main partition) in Disk Utility and enter my encryption passphrase to get access. But RAID adds a layer of obstruction that I have not yet overcome. I used mdadm to scan the above partitions and created the /etc/mdadm.conf file, which I edited to show the 2nd drive as missing (rather than risk corrupting both drives). I activated the RAID array with mdadm, and cat shows:
Code:
root@HERCULES# cat /proc/mdstat
Personalities : [raid1]
md1 : active raid1 sdb3[0]
1815232 blocks [2/1] [U_]
[Code]...
I've been searching the web for hours but have yet to find someone with a solution to this situation. If anyone has a thought on how to access this disk I'd be pleased to hear from you. In the meantime I will start building a new (9.10) machine from scratch, without RAID, 'cos that's probably going to be necessary.

I've installed a Squeeze-based distro - Crunchbang - with an encrypted root partition (no LVM), and it won't boot.
Here's what I get: Loading initial ramdisk. Loading, Gave up waiting for root device ALERT! /dev/mapper/hda5_crypt does not exist. Dropping to a shell!
Here's my partition table:
hda1 - Windows (Truecrypted)
hda2 - GRUB2
hda5 - /
hda6 - unused swap
[Code]...
What should I look for? Where do I go from the initramfs shell? Do I chroot? What then? This might be a Crunchbang issue (although others blame LVM which I didn't use, and it's the original Debian installer after all), but there's gotta be a reason it doesn't boot

I just upgraded my F9 system to F10 using they preupgrade method, and though nothing seems to have failed during the upgrade I can't boot my system any longer.I have a completly encrypted system, and so I need to enter a passphrase at boot. The new F10 system does boot and I do get a Password: prompt but the passphrase is not accepted.My passphrase doesn't contain any odd characters to prevent problems with keyboard mappings. Just plain letters (upper and lower case) and digits
