Hello everyone,

I use Ubuntu (LTS-versions) on my laptop "Thinkpad T60p", and last evening I wanted (finally) upgrade my installtion (12.04) to 14.04.3. During the upgrade (which usually ran very smoothly and pain free) I got several error messages, then it said that the upgrade was over, and I restarted the laptop. Linux booted in text mode (no Gnome).

Today I investigated the situation, and found out the following:
- there are a lot of unresolved dependencies in the upgrade;
- when I try to execute "apt-get -f upgrade", it starts to download, but then I receive a message, saying that there is no place on the drive (there are something like 1,7 GB available), and upgrade stops;
- when I try to release some space (by deleting old/unused kernels, for instance), I cannot do it - due to the unresolved dependencies.

I'm not really newbie to Linux, but at the present I have no idea, how to resolve this issue. I would appreciate any hint, in which direction I should go.

Regards from Hamburg/Germany,
Andrey.

Where is your 1.7 GB of free space? Are directories like /usr in their own partitions? Even experienced users forget about that sometimes...

Sometimes repositories can do weird things. What repositories and PPAs do you have?

Hello wagscat123,

When I installed Ubuntu, I separated /home and the rest. So, my documents are mounted on the separated partition, and all system files/folders are on another. And this one has 1,7 GB free.

So there's 1.7 GB free on your system partition - although now that I think about it, that might not be enough space for the all of the packages in the upgrade to be cached - next time you run "apt-get -f upgrade", see how much space is left on your / partition right when it says you're out of space.

Also, do you have any PPAs or unofficial repos installed?

Hello,

I don't use inofficial repos. Why do you ask?

Greeting,
Andrey

Sometimes unnoficial repos or strange repository configurations lead to interesting situations.

I'm thinking now that you might run out of hard disk space when your system caches all of the .deb files before it actually executes the upgrade. Next time you try the upgrade, pull up another terminal and type "df -h" every minute or two and see how much free space is left as the packages are downloaded and perhaps installed.

Hello,

I suppose it either. Usually I prepare my hard drive for the upgrade, but this time I have just forgotten it. As I said, my main goal for this week-end is purge old kernels I have and try to upgrade again.

Regards,
Andrey

Ok - good luck on that. Let me know how the free space works if it blows up again

Hello,
to solve the issue, I had to resize my "/"-partition to gain more disk space. Upgrade ran through, and I have "only" 2 open issues:
1) somehow my NTFS-partition with Windows data doesn't get mounted via "fstab";
2) my GNOME-session doesn't start, when I enter my login and password;

Not nice, but I think, those issues are resolvable.

Greetings from hamburg,
Andrey.

For GNOME-session not starting, did you try re-selecting the Unity option at the lightdm login screen? Someone also reset some settings to get things to work http://askubuntu.com/questions/53090...r-dash-appears.

For the Windows partition mount, according to Ubuntu's documentation, you'll need this line in your /etc/fstab, except with your Windows partition's UUID (can get from blkid):

"UUID=519CB82E5888AD0F /media/Data ntfs-3g defaults,windows_names,locale=en_US.utf8 0 0"
