Ubuntu :: Recovery/repair - Will No Longer Boot After Removing Packages?
Jun 17, 2011
OK as a recent Windows to Ubuntu convert I made a stupid mistake and now would now like to recover my OS, particularly my files.I had happily been running Ubuntu 10.10 but then used Synaptic to remove Python 2.6 (I was having trouble running Python 2.5 with both installed), I selected to remove Python and all it's dependencies (a bad move as I realise now, as it was quite a dependency list in the end!).
I was left with a semi functional desktop, some things worked but many things were broken / unavailable, neither Synaptic or even Terminal would work to situation.I tried rebooting in the forlorn hope that I would get some recovery options, but it would not boot, boot starts, gets to grub (top left flashing cursor), then that disappears and I am presented with a black screen and nothing then happens. If I then do a hard power down the screen very briefly shows some text (something like enter password) as it shuts down.
Subsequent boot ups just do the same thing. If I boot with an installation disk and move forward to the partition step the original partition is shown as in tact.So, my main question is, is there a way of recovering my OS without the use of low level disk recovery utils (which may be a bit painful and long winded). e.g. what happens if I install 'over the top' of my original installation, will my file system be in tact

So I have been messing around with the new 10.04 and I managed to screw it up. When I started to log off, I closed the lid to my laptop so it would hibernate, but instead the screen went black and I could only see the cursor. It stayed like that for several minutes so I shut it down manually. When I booted it up again, it froze on the splash/loading screen and I haven't been able to boot it since. I've tried to boot in recovery mode, but I think my campus internet interferes with the downloading of the necessary files from the internet. Is there any way to boot a recovery mode from the install disc? Or am I SOL?

This post is a follow up to this one: [URL] My computer is an IBM R52 running Windows Professional (previously dual-booting with Ubuntu 10.10, but that's gone now, and I don't dare reinstall it until the HDD partitions and mbr are properly working again). I think that the shred command mentioned there simply messed up my MBR, and maybe my partition table. Here's the partitions on my HDD:
Code:
Disk /dev/sda: 60.0 GB, 60011642880 bytes
255 heads, 63 sectors/track, 7296 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x7e93bd30
[Code]...
My question is, is it safe to use something like SuperGrub to repair the MBR? I really don't want to mess up the Windows and recovery partitions. I've done plenty of research on this, but am not confident until someone says that it works in my case.

I have several CDs of diagnostic and recovery software (most of which are dated) but never seem to have them around when i could use them the most. Then it hit me: use a flash drive. i usually carry two flash drives around with me, so i loaded one 4GB with diagnostic/repair tools from PortableApps.So far I have CCleaner, John the Ripper, Recuva, an antivirus, and SIW (System Info. for Windows). I still have plenty of space left and was wondering what you all's favorites were, or what i might add. I'm looking to have somewhat of a suite, something for any occasion (within reason, of course.)I think everything right now i have is PC-based. i just want a suite of tools in case anyone has a non-hardware issue.

I have added to Debian Wheezy testing repositories. After a restart there is no desktop anymore just the wallpaper picture is visible but no desktop pop-ups.
When I want to install the desktop through recovery mode, I get an error message that it "can't fetch...repos". How I can repair /etc/apt/sources.list through recovery mode?

As a suggested fix to solve a problem with cairo-dock, on 5/2/10 at 11:00pm, I ran the following in a 9.10 terminal window:Code:sudo apt-get dist-upgradeThis somehow deleted all of my kernel images, and a bunch of other files.I'm running the livecd now. Is there any way to run dpkg from the livecd on my mounted HDD? I can't access anything while booting up the HDD except for memtest in the grub, so going into recovery mode is impossible.

I'm running Ubuntu 9.10 on a 250GB drive and have Windows 2K on a 40GB drive. I have noticed that the 40GB drive has got quite a few bad sectors appearing on it, so it looks like it's going to give up the ghost soon.I have decided to do away with the 40GB drive and Win 2K because I never use it, the question is if I just remove the drive what are the consequences if I do that? Apart from still seeing Windows 2000 in the bootup list. I've never tried this hence the reason for the question

I've got an 8-disk raid-5 setup, and one of the disks failed. I shut the system down, replaced it, and powered the box back on again. Then, I made a catastrophic mistake; I 'failed' and removed the wrong disk (should have been sdj1, and I typed sdk1 by accident). I tried to re-add sdk1 back to the raid array, but it got listed as 'spare'. My raid array is off-line, since I now have 2 disks unavailable.
I know that the data still exists on sdk1, is there any way I can get the raid array to recognise the fact that it's a valid part of the array, and not a spare disk? At least if I can do that, I'll have a degraded but accessible array, and then I can rebuild the array on the properly replaced disk.

It all started Tuesday morning. I woke up and turned my computer on. Normally I just leave it on all the time, but I turned it off the previous night for some reason. When I turned it on, everything worked fine for about 10 minutes, until my monitor said "Monitor Working Out of Scan Range." I messed with the settings on the monitor to try and get it back, but to no avail. Restarting would make it work, but for even shorter periods. It eventually would display the manufacturer image (Everex), and then go dead again with the same message.
I thought it was the monitor at first, and got a new one. The new one is a wide screen 18.5 inch Dell IN1910N. The problem persisted, so I knew it wasn't this. I kinda figured it out when I started smelling something burning coming from my computer, and discovered it was the graphics card I installed awhile back. It is the pci ATI X1550, and its fan no longer worked.
So I figured, well, I will just remove it and go back to the onboard video. Doing this worked fine, until I got to the stage where it tried to boot to the Xserver, and then the computer just hangs. No sounds indicate I ever get to a logon screen or anything.
Now, I tried commands like sudo dpkg-configure xserver-xorg, and it asked me a lot of questions about my keyboard, but didn't fix my video. I also tried the "Xfix" option in recovery mode, and it purged all the old fglrx drivers, but that didn't help either.
I am currently using a live CD (I was doing straight command-line for awhile, after I also played hell getting the wireless working). I tried literally coping and pasting the entire contents of the X11 folder over, but that didn't work either (the xorg.conf files were the same anyway). I don't know what to do to get my old partition to boot X correctly.
All the commands I was copying before are not in my terminal now, and I'm not sure exactly what command-line information you need. I know that Openchrome is supposed to run the onboard VIA video, but I don't recall the command that tells me everything about it.

When removing packages via Synaptics it gives the option of Mark for removal Mark for complete removal If I mark it for complete removal does it mean it will never be available from Synaptics again or does it mean that the whole package will be deleted from my system and have to be downloaded again if I want to install it again. I am never sure which to pick

I'm using Ubuntu 10.04 and during my tries to free space I've removed several packages such as: openoffice, all editors, and some more packages such as players and printers drivers that I don't need and seem o.k to remove. However, after restart, the graphical interface doesn't load, I'm in the xserver, I have console but not gui. I was wondering if anyone can tell me which packages I should not remove or let me know of dependencies I need to consider when messing with packages?

I need to remove a lot of rpm packages and I would like to save some time and make things easier, but I am unsure of how to do it. Currently I just copy/paste over and over. My plan was to put the output of the command below into a text file, and use that text file to remove all the packages.
rpm -qa |grep xxxxx > file.txt
My question is how do I get that file to work with "rpm -e". I tried to insert the file using the less than symbol but that didn't work:
rpm -e --nodeps < file.txt

I recently did upgrade from F12 to F13 using preupgrade, and I was following the guide from the Fedora project website [URL]
On the section Removing unsupported packages it shows how to find orphaned packages and sugest you remove them. I tried that, found a bunch of packages that I promptly erased. But then I
came across
ModemManager-0.4-5.git20100720.fc12.x86_64
I thought "well I don't use a Modem" so I tried to yum erase it. I stopped when I saw that it was trying
to also remove the dependencies, a bunch of NetworkManager packages.
My question is, why is ModemManager flagged as an orphan if it has packages depending on it, isn't that wrong?
And also, the recommendation on the guide to remove these packages can be dangerous to people who don't pay attention (imagine someone accidentally removing NetworkManager, no internet).
I will keep the "orphaned" package out of necessity, but something is wrong in this whole deal.

In trying to get something else working, I installed a newer version of the kernel from backports (I'm on 2.6.26 lenny and the backport kernel is 2.6.32). That failed, so I want to remove the backport kernel completely.
I tried:
Code:
and got:
Code:
Accept this solution? [Y/n/q/?]
I don't really understand how these metapackages work and I don't want to accidentally remove my currently-working kernel.
What's the correct way to remove all packages related to the backports kernel and leave the existing lenny ones alone?

I downloaded ubuntu 10.10 iso, made CD, installed as dual-boot with win Vista home premium and used it for a week to access the 'net and email. Yesterday, while deleting an email, the "d" key stuck down while I was issuing <CTRL>D and the cursor froze. I then rebooted by using the reset button and saw many lines of text including "kernel panic". so I reset and booted into 'repair boot'. Again, many lines of text which stop at the same place if I try this twice.
I assume I've fried my ubuntu install and would like to fix or re-install it. When I installed it, I let the [wubi?] installer make decisions except choice of drive because it picked the external, USB drive. It appears to've used about 80 G on internal drive D: I could boot from the distro CD and see if it will re-install but I'm concerned that I may not fix my problem or that it may mess up my windows installation.

I have a fresh Debian install, since this install was on a desktop, I had an internet connection and didn't notice (it was late, I was half asleep) I opted to download a whole load of packages I didn't really need. I thought all was doomed until I remembered that I have done another Debian install but a week ago on a laptop, which has a nice clean install without all the bloat.
So I ran dpkg --get-selections > selections
and had it sent to my new desktop installation.
Now if I run dpkg --set-selections < selections followed by dselect-upgrade nothing happens. I assume this is because the smaller list contains all the packages 'to be installed' which already are, and all the missing packages are not being purged. Do I need to explicitly add all the packages I want to purge to the 'selection' list or is there a better way of doing it?

I have an issue with packages. When I try to install any package then I receive error like this one below.
e.g. install Lynx:
Code:
# apt-get -f install lynx
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libperl5.10: Depends: perl-base (= 5.10.0-19lenny3) but 5.10.0-19lenny2 is to be installed
libsnmp15: Depends: libsnmp-base (>= 5.4.1~dfsg-12) but it is not going to be installed
lynx: Depends: lynx-cur (>= 2.8.7dev9-2.1) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
So I decided to remove libperl5.10 which apparently mess. But its not that easy, just take a look:
Code:
# apt-get --purge remove libperl5.10
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libsnmp15: Depends: libsnmp-base (>= 5.4.1~dfsg-12) but it is not going to be installed
Depends: libperl5.10 (>= 5.10.0) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
...and now I don't know what to do ?

I have XP, Win7 Pro and F 11 installed. Before I installed F 11, Win 7 boot mgr was working fine. I then installed F 11 and I went to System/Admin/bootloader to edit it and it wouldn't bring up the boot loader. In the attachment was the error msg. Now my only option when I boot up is F 11.
I do not have access to the Win 7 DVD only the F 11 install disk since I am on a fishing trip and need to use Win 7. How can I repair to the grub boot loader to boot into Win 7?

I updated and removed some packages that could not be upgraded, and now Firefox and Google Chrome show web pages in bold font by default. By this i mean that all pages not setting font-weight explicitly.
This is on Meerkat, upgraded from long before (Lucid, i believe). I'm guessing the KDE packages are due to me having Amarok and konsole installed some time long ago, so i assumed i could ditch these.The terminal output from the commands above is attached.

I am new and recently almost one month back installed debian linux stable 8.2 came from windows. Today I upgrade my debian stable 8.2 to testing and everything works fine. Just one thing is that I checked kernel and find :
uname -r
4.2.0-1-amd64
dpkg --list | grep linux-image
ii linux-image-3.16.0-4-amd64 3.16.7-ckt11-1+deb8u5 amd64 Linux 3.16 for 64-bit PCs
ii linux-image-4.2.0-1-amd64 4.2.3-2 amd64 Linux 4.2 for 64-bit PCs
ii linux-image-amd64 4.2+68 amd64 Linux for 64-bit PCs (meta-package)
I am first time removing old kernel so cant take risk from searching the solution from google so come here, what and how to remove that includes everything like kernel image and other old kernel files not needed.
One more thing I just realised and saw on details in settings gnome that
Base : Debian GNU/Linux stretch/sid 64-bit
Is this right as it says sid in the line but i just changed my sources.list to testing only and then aptitude upgrade and full-upgrade then just.

Mint 11 32bit
I got an Upgrade manager notification in my panel so clicked it to see what needed upgrading. However when I went to upgrade I got an error message saying I had to fix broken packages first. See Screen shot. I opened Synaptic and this says there are no broken packages see synaptic screen shot... Is there a CLI way to look at and repair installed packages? (I checked other threads on LQ and found some advice for Fedora 8 which suggests running an rpm command, however rpm is not the package manager of choice for Mint.)

I recently upgraded my x86_64 system from FC8 to FC10 using Pre-Upgrade. (related blog link) It appears that the upgrade process installed a steaming pile of i386 packages that are duplicates of existing x86_64 packages. I now get update errors because of this package clash. I have searched the fora and the most progress I've been able to make so far is: I apparently had 8 unfinished yum transactions so I did yum-complete-transaction 8 times and have no more incomplete transactions.
The output of package-cleanup --dupes is not very helpful:
Code:
[tim@servy ~]$ sudo package-cleanup --dupes
Setting up yum
Loaded plugins: refresh-packagekit
Yet I still get transaction errors when I run updates via synaptic. It checks dependencies and downloads everything and errs when testing changes. This is the error it gives at the moment:
Code:
Test Transaction Errors: file /etc/gconf/schemas/gweather.schemas from install of libgweather-2.24.2-1.fc10.x86_64 conflicts with file from package gnome-applets-1:2.20.1-1.fc8.i386
