Public bug reported: Repeated failure of xubuntu/ubuntu updates repeatedly causes my system to crash severely.
I recently had to reinstall my operating system after a failed update. I may now have to do it again. The cause is this perennial problem of the root partition getting full up within weeks of a fresh install. The o/s is not able to administer its partitions properly. This is a severely obstructive problem. Most recently: 15 June 2014 -> routine updates to Xubutnu 14.04 (Ubuntu 'Trusty' LTS). The update crashed with the following message: "The package system is broken. If you are using 3rd party repositories then disable them since they are a common source of problems. Now run the following command in a terminal: sudo apt-get install -f" I had standard repository options enabled for Canonical Partners and independent providers. I unticked these and ran the command. It said: """ The following packages have unmet dependencies: linux-signed-image3.13.0-29-generic Depends: linux-image-3.13.0-29-generic (=3.13.0-29.53) but 3.13.0-29.53 is installed Depends: linux-image-extra-3.13.0-29-generic (=3.13.0-29.53) but is not installed linux-signed-image-generic Depends: linux-firmware """ The operation rendered my computer unusable. On restarting my machine, my keyboard didn't work at the encryption password prompt. I tried some obvious ways to get round this but without success. (E.g. I tried booting from the most recent CD I had to hand (Ubuntu 12.10). Booted okay but it did not recognize any of my encryption passwords so I could not get at my data). The keyboard worked during Bios startup. I could use it to operate my boot menus. It just froze when the o/s loaded. It is most important as a user that I stress this point: I *eventually* found out that I could opt to load a different kernel and thus gained access to my computer. I booted using the 3.13.0-24-generic option instead of the 3.13.0-29-generic option my o/s wanted to load as default. But this did not solve the o/s problem. I tried looking in Synaptic (a tool I must confess does not get used because I am not an administrator, I am a user and Synatpic is out of my comfort zone). Synaptic said: "You have two broken packages on your system. Use Broken filter to locate them". I did this. Synaptic showed my two broken packages: linux-signed-image-3.13.0-29.generic installed version: 3.13.0-29.53 linux-signed-image-generic installed version: 3.13.0-29.35 Thinking it was time to file a bug report (and contemplating whether switching back to Windows was the lesser horror or whether I should just accept that I must reinstall linux every few weeks), I ran the Software Center - I remembered that the Software Center had an option that displayed update history and I reckoned this might be useful info for a bug report. Software Updater said on starting: "New software cannot be installed because there's a problem with the software currently installed". It gave two options: <cancel> <repair> It is interesting to note here that the only point when the system offered to repair the broken update was not when it happened, nor after restart when its failures became apparent, but after a prolonged, distressful attempt to rescue lost data and a chance invocation of the Software Center. This presupposes that your system isn't broken. Because if it was then you wouldn't be able to run the Software Center, unless you happened to know that you can rescue a system by loading an old kernel image. Assuming you had not in your amateur struggles with linux's prohibitively thorny bugs not deleted all your old kernel images, your only chance of knowing this as a mere user is after years of hair-wrenching trial and error: because there is nothing inherently instructive, guiding or instinctual about linux that would lead a user to this knowledge. I clicked <repair>. The repair failed. Software Center said: "The new software couldn't be installed because there is a problem with the software currently installed.. Do you want to repair the problem now?" It gave two options: <cancel> <repair> Its error output read as follows: """ installArchives() failed: (Reading database ...

""" If you happen to be either paid, nerd or fool enough to look closely at this output you might discern that the problem was a disk full problem. (E.g. "failed to write (No space left on device)"). If you have been using linux for any amount of time (and incredibly - are still using it), you might recognize in this the recurring nightmare that is the root or boot partition getting full of refuse. It seems the nightmare has just got worse. For all the wails of pain. For all the bug reports and appeals for help. It has got worse. The innumerable how-to-fix posts you will find for this bug typically lead to the discovery of a huge pile of trash that the o/s has left the user to clean up - in the form of old kernel images and their associated refuse. Really, an o/s that lets its trash pile up till it breaks the system and puts the user back in hell, again and again and again - it's a curse. It all becomes a bit too much. You get sort of punch drunk as a user. The last time this error occurred, I looked up for the fix again, and came across some post on an official Ubuntu forum with a command to automate the process. I giddily typed it in. And it broke my system. I had urgent work deadlines. It is quicker to reinstall the o/s from scratch than to try and resolve the problem in forum hell. But this wasn't the problem this time. I probably will just reinstall the o/s. But for the sake of a bug report, I tried to find out more about it. It was not a boot full problem, as is often reported: $ df -h /boot Filesystem Size Used Avail Use% Mounted on /dev/sda1 236M 71M 153M 32% /boot It was a root full problem: # df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/Bonzo--vg-root 314M 287M 6.8M 98% / But there's nothing in my root to that uses as much as this reported 278M.

There appear to be only two kernel images here. So what on earth has caused the trouble? I got the listing after following the instructions here: http://askubuntu.com/questions/266825/what-do-i-do-when-my-root- filesystem-is-full (Just one of many, many fixes for this bug you will find online if you want to dizzy yourself with trying to find a solution and have nothing better to do, like earn a living). That bug fixer's suggestions did not apply to my case. It said, for example: 1. I have might have core dumps filling up the disk. I used its given command to learn that this is not my problem. 2. I might have unnecessary packages filling up my disk: Following its instructions here just repeated the error I'm trying to correct: # apt-get autoremove --purge Reading package lists... Done Building dependency tree Reading state information... Done You might want to run ‘apt-get -f install’ to correct these.

Try using -f. 3.

I.e. I used the standard options given by the installer, if I remember correctly. It says, do you want to have encryption, separate partitions and LVM. I tell it, having come to the conclusion after years of using linux that these standard install options are desirable, 'yes, yes and yes'. It has left itself without adequately- sized partitions, and me with a headache and the inglorious task that befalls a user who cares enough, of complaining. ** Affects: thunar (Ubuntu) Importance: Undecided Status: New ** Tags: bugs -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1333386 Title: Package system broken, update failed, keyboard failed on boot, root partition full To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunar/+bug/1333386/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
