Good evening! I'm not sure if I've found the right place to pose this question, but I'm having difficulties upgrading to Ubuntu 12.04 Beta due to a problem with the dependency cycle. I took a screenshot of the error and have attached it. I would be very grateful if I could get some help working through this. Thank you!

12.04 LTS is unreleased and beta. Expect breakages, bugs and glitches.

I have asked mods to move this post to the appropriate forum. ;)

I hasn't been released for upgrading yet. If you want to run it, you'll need to download the iso and install.

Please go to this link and look for the heading Upgrades.

You will find this written there:


In some cases, the package manager in Ubuntu 11.10 may not be able to decide on a correct unpack ordering when upgrading 64-bit systems with the ia32-libs package installed; if this is the case, it will fail before starting to unpack any new packages with a message something like "Couldn't configure pre-depend libtinfo5 for libncurses5, probably a dependency cycle". A workaround is to install the apt and libapt-pkg4.12 packages from precise before starting the upgrade. (924079 (https://bugs.launchpad.net/bugs/924079))

That's this bug:

The work-around is in comment #23.
