Ubuntu Security :: There Is No Application Installed For PGP / MIME-encrypted Message Header Files
May 22, 2010
I recently had to reinstall ubuntu, so I backed up both my ~.gnupgp and ~.gnome2 folders and copied them over in the new installation. My old keys show up just fine in the password manager, but when I attempt to open a file encrypted with one of them, I get the error: "Could not display (name of file): There is no application installed for PGP/MIME-encrypted message header files"

After trying Truecrypt, LUKS, and Ecryptfs I decided to try NTFS encryption. Now, on a dual boot computer from Ubuntu I can browse the encrypted folders but can not open the encrypted files. All attempts produce access denials yet the Unix file permissions appear to be "0777" (owner, group, and world readable-writable).
Is there someway to get Ubuntu's NTFS software to recognize and decrypt the encrypted files? Would a different NTFS package work such as NTFS-3g?

I installed Ubuntu 10.10 64 on my laptop with the entire 500gb setup as encrypted LVM. This has worked well for several months with no problems. During this time i have been backing up the data to an external usb drive (1tb) on a regular basis. The usb drive was not encrypted. So, I thought it would be a good idea to encrypt the backup drive too. I wiped out the backup drive and set it up as one large encrypted lvm and mbr. This seemed to work fine but immediately afterwards I decided to erase that and set it up as encrypted lvm guid instead of mbr. I couldn't delete it while logged into my desktop so i decided to do it from a bootable gparted usb stick. In gparted i erased the 1TB backup drive once again and planned on setting it up the way I wanted once I was logged back into my ubuntu desktop. Now I cant boot into my desktop with the following errors:
cryptsetup: evms_activate is not available b0d) does not begin with /dev/mapper/
Then after waiting for a few minutes I get an error followed by (initramfs)
When booting from a live version of ubuntu the 250MB boot patition is recognized and 500 partion is there but it is labeled as empty/unused.
Also, I did choose to use the exact same passphrase as what is used on the main bootable drive when I set up the encrypted partition on the external 1TB drive.

I've just started using ubuntu one. However, some of the files I store on there are sensitive so I encrypt them using seahorse. Right click, encrypt etc etc. My question is, is there a way to automatically get the encrypt process to delete the un-encrypted file when it makes the new encrypted copy?

I am debugging a project and I noticed the .so files from my installed version of this project are being used when I run the main executable. However what I want is that the modified and compiled libraries (.so files) are being used. This is for testing the software. So I don't want to install these. I tried adding the directory with the .so files in /etc/ld.so.conf and doing ldconfig. However that did not seem to work. How can I let the main executable use the modified .so? I also want to debug this using gdb, so if someone knows what I should do to get those modified .so files being used for execution.

I'm trying to use TCM (Toolkit for Conceptual Modeling) but the font used by the application for menus window headers & such is very hard to read. I can change the font used for fields within the application in the configuration file, but there doesn't seem to be a way to change the fonts for the other fonts.
Is there a way to do this through gnome or Ubuntu?

I installed MS office 2003 via wine on Slackware 13. I need to know how to associate files with the right Office (msword, msexcel, msppt) program. I made launcher scripts that can launches office files from the CL, but the user on this computer will want to be able to just double click a file in dolphin and have the right office program come up.For some reason all office files show up as x-ole-storage instead of application/msword or something similar. So, even if I tell Excel to associate with that file, it will do it for Word and PowerPoint files as well.
.ppt, .doc, and .xls extensions were configured via the KDE file associations panel, but this did not help. I played around with the raw files under ~/.local/share, but I did not find the solution.The version of WINE is 1.1.24 (built from SBo SlackBuild).

I've got an apache-svn server up and running fine but I'm struggling with an irritating problem. I need the apache server to display .vbs, .cs., vb., .sh, .pl., .c, .h, .cpp, etc, etc files in the browser. Whenever our users click on a script they get a download dialog instead of the script being displayed in the browser as plain/text. I have added:
Code: AddType text/plain .vbs Into /etc/apache2/mods-enabled/mime.conf but it seems to be getting ignored. how I can tell apache to treat script files as plain-text?

When connecting to an unknown unsecured wireless network, is it possible for someone to capture a header and resend it even if it's over https? For example I login on an ipod or on a computer and connect to a server through https and password auth. Although anyone monitoring the transmission could not get hold of my password since it's encrypted, could they just capture the header and resend it 5mins later to logon again without even knowing the password?

When is it good to use separate translation units and object files and link them into the main C program, and when is it good to include the header files in the main C program? I don't understand if most people include header files or if most people just link in object files and use their contents in the main program. It's sort of a simple question, but it's confusing to me and that's why I need help with it. I sort of don't understand the difference, or if there's really no difference other than the way the final result is achieved, which way is better or preferred, etc...
For example:
Code:
or:
Code:
Simple explanation of the difference? or which one is preferred or better? I've read a little on the ELF format... so is there no difference in the end result? It's just a matter of preference or necessity, and where the information is to begin with?

I am running Pclinuxos with KDE 4.3.4. I have installed Truecrypt but am having problems using this program when the user is not root. If I try to mount or make an encrypted container a message pops up saying: Administrator privileges required: enter user password or administrator password
When I enter the root password a box then says: Failed to obtain administrator privileges: username is not in the sudoers file. This incident will be reported
I can't understand why this has happened as I gave the root password. Once I provide the root password, surely I become all powerful and the system should let me do anything? Also to mount a encrypted file in Truecrypt I have to assign full write permissions for users to the /media directory. Is this safe to do?
The only way I have found to use Truecrypt with a non root user account is to go to super user mode terminal, sign in with root password, CD to the truecrypt directory and launch Truecrypt from the terminal. I find this very laborious to do every time.

I tried to update the header files manually in the include folder, because I thought that I needed to have windows.h etc, but now nothing compiles and I get a good 80 errors for even hello world. I have tried removing g++ and all related packages, deleting the header files folder and reinstalling, but it reinstalls the broken files. Any way of restoring the originals without reinstalling ubuntu?

I am new to linux. I want to use a header file asm/msr.h. But the /usr/include does not contain the header file that I want. Can I just copy the whole asm directory into the directory /usr/include, and overwrite the old one?

I've installed Fedora 12 (KDE version) on VMware workstation running under Windows 7.
I've been able to configure the VMware tools fine up until this point:
Code:
What is the location of the directory of C header files that match your running kernel? After some searching online I deduced I should install all of the latest updates and kernel-devel.
I then nuked the previous VMware tools install and started over with it again, but alas, no directory I try works (i.e. /usr/src/kernels/, /usr/src/kernels/2.6.31.5-127.fc12.i686/ and so forth).

I'm trying to add a header to many .cpp files in a directory (or directory tree).
My attempt was:
Code:
If I put part of the command inside quotes the substitution occurs, but then I get other errors like:
Code:
cat:
No such file or directory
I could just write a small program to do it.

I'm trying to install vmware tools in mint.
All goes well until I get to this -
What is the location of the directory of C header files that match your running kernel? [usr/src/linux/include]
When installing the vmware tools it says to just hit enter and the default will be used.
Hitting enter just keeps giving me the error message- The path "usr/src/linux/include" is not an existing directory.

I am trying to configure VMWare tools to work with the linux-virtual kernel, but every time I supply the headers path to vmware-config-tools, it rejects it. What should I do to configure it?I am using the path:/lib/modules/2.6.35-23-virtual/build/includeBut I get the rejection message:The path "/lib/modules/2.6.35-23-virtual/build/include" is not valid.It works with the generic version, so what am I doing wrong?

Not I recently installed a package (Vision Egg) that requires the Open GL libraries and headers, specifically, gl.lib and gl.h. I used Synaptic to install nvidia-current and nvidia-current-dev and it now looks as if the required libraries (under different names) are installed in /usr/lib/nvidia-current and as if the required headers are in /usr/include/nvidia-current. I am a bit confused because I also have /usr/lib/nvidia and /usr/lib/nvidia-173.
The installation of Vision Egg fails with "cannot find GL/gl.h" and "/usr/bin/ld: cannot find -lGL"There is a related post a few years ago under thread 200901 but it relates only to a single file problem that is fixed manually. I'd rather avoid that because it looks like it is easily breakable.Is there a standard way --- that is, a method that does not require error-prone manually changing or linking a multitude of file names --- of ensuring that programs which require GL/gl.h actually find the correct nvidia header file and also that the link loader finds the GL libraries.

I need to install some module which needs to be interated into OS's.
It asks me: "What is the location of the directory of C header files that match your running kernel? "
I know that I need kernel-devel package and I installed this yum install kernel-devel after that I have this /usr/src/kernels/2.6.32.26-175.fc12.i686/include/
Now when I run configuration it does not work
Does it mean that I need to update the kernel so that it matches to the kernel-devel module available in the net?

I want to use kmalloc() to allocate contiguous memory on ram. But I can not seem to find the required header file(s) like linux/slab.h. I suppose I do not have the required library and I certainly do not know what and where to look.
