update-manager free space check broken when /var/cache/apt/archive is a symlink

Thanks for your bugreport.

Can you please attach the files in /var/log/dist-upgrade ? This will help us diagnose the problem.

Thanks,
 Michael

term.log was empty

From the main.log, I suppose that the correct mount-point isn't found
18:13:36,050 DEBUG Dir /var/cache/apt/archives/ mounted on /var

but in actual fact, /var/cache is a symlink to another fs.

BTW, the symlinks command
$ symlinks /var
other_fs: /var/cache -> /local/cache

shows that it's on another fs, however, this command isn't installed by default :-(

Here is a patch that should work. Please test it with the following commands:
$ mkdir /tmp/upgrader
$ cd /tmp/upgrader
$ wget http://archive.ubuntu.com/ubuntu/dists/feisty/main/dist-upgrader-all/current/feisty.tar.gz
$ tar xzvf feisty.tar.gz
$ patch -p1 < symlink-fix.diff
$ sudo ./feisty

and let me know if it fixes the issue.

Thanks,
 michael

If your /var/cache/apt/archives dir is symlinked and you get this error, you can workaround the problem editing (or creating):
/etc/apt/apt.conf
with the following line:

Dir::Cache::archives "/path/to/your/archive/dir";

Thanks for the fix, the symlink patch changes the behaviour so that it doesn't cancel for lack of diskspace anymore. I haven't actually started the upgrade yet, but I see no reason why it wouldn't.

Of course, requiring so much diskspace in /var is rediculous, as well as the by default not-cleaning after apt-get install is run. But that's another bugreport ;-)

Dear All,

I had a similiar problem to during updating from 6.10 to 7.04.
The installation seems to crash after the following exception in the KDE Adept Manager:
<<
2007-04-20 20:03:44,648 ERROR Exception in KDE frontend (invoking crash handler):
2007-04-20 20:03:44,759 ERROR Traceback (most recent call last):
  File "/tmp/kde-root/adept_updater4oTfjc.tmp-extract/dist-upgrade.py", line 56, in ?
    app.run()
[....]
OSError: [Errno 12] Cannot allocate memory
>>
I have attached the two documents in /var/log/dist-upgrade as requested.

However, after a restart the new version seems to be installed.
How can I find out if the installation has been completed correctly and my system works
stabil as before?

Many thanks, of course

Regards
Heiko

I am having similarish problems with not enough disk space but in my case it is the boot partition that has the problem. The main.log says that the Upgrade manager requires 41M free space on boot but my whole boot size is only 45M. This more than enough for all normal operations and I can have two or three boot images available without any problems. I have three partitions, /boot at 45M, swap at 500M and / at 92G with 85G still free. There was never any advice in any of the installs that /boot should be a minimum size to allow upgrade manager to function. Is there any way to use the large free space on / or is my only option to do a complete re-install from a downloaded CD iso? I paste in here the relevant sections of my main.log file:-
