Loaded new 9.04 box, applied updates, libmagickcore1 and mono-jit have issues

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that there was an error on your system when trying to install a particular package. Please execute the following command, as it will clear your package cache, in a terminal:

sudo apt-get clean

Then try performing the update again. This will likely resolve your issue. If so please set the bug's status to Invalid. Thanks in advance!

I apologize, this ticket is only about 9.04 systems. I seem to have intermixed 8.04 and 9.04 previously. Updating the title of the ticket.

I tried your apt-get clean suggestion, still does not clean up the crud caused by Update Notifier silently started while Synaptic was updating the system.

The file /var/lib/dpkg/alternatives/cli looks corrupted. If it's still an issue, could you please attach it to this report and try to run:
sudo apt-get clean
sudo apt-get update
sudo apt-get install --reinstall mono-git libmagickcore1

Thanks.

I tried the three apt-get commands, and the install produced the following output:

$ sudo apt-get install --reinstall mono-git libmagickcore1

E: Couldn't find package mono-git

Going in Aptitude, I do not even see mono-git. Has that package been renamed or something since I originally loaded this box?

After that, I appled all available updates via Aptitude, and the updates applied, and at the tail end the same mono-.... aaarrrggg...

mono-jig not mono-git!!! I shall try again in this case... Bye!

With the corrected package name - error seems to yet persist... (All thanks to Update Notifier getting caught in the gears of Aptitude working. gggrrrr..... head shaking... do I need to open a separate bug against what I observed Update Notifier doing here?)

$ sudo apt-get install --reinstall mono-jit libmagickcore1

The file /var/lib/dpkg/alternatives/cli is certainly truncated ( size of 0 )

Remove that file (just move it to another place)
$ sudo mv /var/lib/dpkg/alternatives/cli ~/

You can then the broken file by running :
$ sudo update-alternatives --install /usr/bin/cli cli /usr/bin/mono 10 --slave /usr/share/man/man1/cli.1.gz cli.1.gz /usr/share/man/man1/mono.1.gz
$ sudo update-alternatives --auto cli

Then try performing the upgrade of mono-jit again.

I hope this helps.

Woo hoo! That finally resolved the errors! Thanks so much, Jean-Baptiste!

Thanks for following up. I'm closing this report due to your last comment. Don't hesitate to submit any new bug.
