how to solve dependency problems

Asked by Mohan D

After upgrading from Gutsy to Hardy, I get these kinds of error reports whenever updates are installed. I have no clue about these issues and I am new to Linux. Can someone explain these error logs? I am still able to use Hardy for my normal usage and I do not see any problem whatsoever, excepting my webcam, which is not working after upgrade.

E: linux-image-2.6.24-12-generic: subprocess post-installation script returned error exit status 2
E: linux-ubuntu-modules-2.6.24-12-generic: dependency problems - leaving unconfigured
E: linux-image-generic: dependency problems - leaving unconfigured
E: linux-restricted-modules-2.6.24-12-generic: dependency problems - leaving unconfigured
E: linux-restricted-modules-generic: dependency problems - leaving unconfigured
E: linux-generic: dependency problems - leaving unconfigured

Hardy will not be released for another month. Upgrading now is a bit premature. The beta version is out so running that is fine if you wish to help discover and report bugs.

As for the error, I'm not sure. What does the contents of /etc/apt/sources.list look like? are the repositories for gutsy or hardy? If gutsy that could be the issue. If hardy, try running the following in a terminal (apps - accessories)

sudo dpkg --configure -a

Thanks for the response.
I always want to explore and learn. As you said, I want to discover and report bugs. The contents of /etc/apt has many source.list_backup_xxxx files. Aaprt from these backup files, there are three files, viz., sources.list, sources.list.distUpgrade and sources.list.save file. The first file opens up Software Sources dialog. This does not say whether the repositories belong to Gutsy or Hardy. The second file indicates Gutsy repositories and the third indicates Hardy repositories. Many unsupported third party repositories were added by me since I was using Fiesty. I am not sure whether they cause any problem. I ran the last command given in the reply and the results are copied below:

probably your sources list is messed up. If you can run gnome, try choosing another server from synaptic.

I tried your suggestion and it did not work for me. I decided to go for a clean Hardy install. I do not have this problem any more. Thanks.
