[Bug 1157054] Re: When a filesystem is running out of space, Ubunutu shall provide a clear message and an easy solution

[Michael Opdenacker]

I've just had this issue that can happen to anyone. My /boot partition
was almost full when I upgraded to 13.04.

I did remove unnecessary kernel packages which solved  my problem, but
user who don't understand all this may be puzzled.

During kernel upgrades, is there a mechanism to remove kernel packages
which are obsolete? As far as I am concerned, at least on my Ubuntu
servers, when kernel n is the latest update and seems to work fine, I
just keep kernel n-1 and manually discard older  versions. All this is
manual though, and I forgot to do this on my desktop system.

  Hi,

  I am using a fresh 12.10 as a simple end-user since 5 months.

  Yesterday I launched the Software Updater and got the following message :
  - The volume "boot" has only 2,2 Mo disk space remaining
  Followed by (approximately) :
  - You can free some disk space by deleting unused software or files, or by moving files to another disk or partition.
  With an additional "Examine..." button, which opens baobab on the /boot partition.

  What happens : Ubuntu provides a technical message and no clear solution.
  What should happen : Ubuntu provides a clear message with an easy-to-go solution.

  My thoughts :

  1/ It might not be a good idea to tell an end-user to delete files or
  software in /boot.

  2/ Talking about "moving files to another partition" might be
  incomprehensible for an end-user.

  3/ Baobab did not help me (it certainly can, but obviously I did not
  get how)

  4/ I have been searching over the Internet / Launchpad / AskUbuntu and found that many people are facing this issue, but that there is no out-of-the-box solution :
  - old and new bugs : Bug #237035, Bug #76521, Bug #1067106,
  - hints to use "computer-janitor" (however now, both the dash and USC can not find it),
  - hints to use "sudo apt-get clean",
  - hints to use even complicated solutions (http://askubuntu.com/questions/89710)
     > sudo apt-get purge $(dpkg -l linux-{image,headers}-"[0-9]*" | awk '/ii/{print $2}' | grep -ve "$(uname -r | sed -r 's/-[a-z]+//')")
