Everything I've found where people are having trouble fetching packages for updates, they seem to be getting explicit error messages, but I don't see any. Click edit and change the option under 'Distribution' from 'maya' to 'precise'. If the above said option fails: It would of better if you could check which packages are being held back.If you have added ppa directly with apt-add-repository command then it might setup the ppa for maya ie(Mint). If the package belongs to the ppa then nothing much can be done other than to disable that ppa.
Level 3 updates should be applied selectively and with caution. In the Update Manager, click on the Refresh button to check for any new version of mintupdate and mint-upgrade-info.
If there are updates for these packages, apply them.
And most of the ignored ones are translation packages. Only thing which you should worry is if at the end of update process it throws out error saying some packages couldn't be updated.
I ran sudo ppa-purge ppa:jamesodhunt/bug-829980 and now my problems are much much worse.
Specifically I added the repository for a particular bug-fix which didn't seem to work, I think because the repository is being ignored.
I can't seem to find any references anywhere to other people having the same problem.I'm new to Linux Mint 12 and I can't tell for sure, but I think I'm missing some updates.When I run update manager and it's fetching the list of packages to be updated, a bunch of packages list status: failed.And when I run sudo apt-get update, a couple packages say Hit but most are listed as Ign (which I assume stands for Ignored).I know that Mint purposely avoids installing some updates because they're not yet considered stable, but this looks like it's not even fetching the list of available updates.You do not need to apply level 2, 3, 4 or 5 updates to upgrade to the new version of Linux Mint, and doing so won’t apply these for you.
