Your sources.list entry is wrong. For Waldorf/wheezy, it would be this (replace 'us' with your mirror)...deb http://ftp.us.debian.org/debian/ experimental mainIt's in the experimental repo, but these Firefox/Iceweasel updates are so incremental that there's nothing experimental about them, IMO.
So I'm playing around with offline package installation on 12.04 Server, having downloaded packages by retrieving and wgetting their URIs using the instructions here: http://www.webupd8.org/2009/11/get-list-of-packages-and-dependencies.html
I did this with apt-get upgrade and apt-get dist-upgrade, then went about installing the downloaded packages using dpkg -i.
/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found
What I did before was add the Debian experimental repo and update to 2.17. But through a long chain of events, this ended up breaking almost everything on my system, and I had to reinstall. Is there any way to upgrade just this single package, without screwing up apt?
Just upgraded from 13.10 to 14.04 today. . . the upgrade finished but displayed an error dialog stating that "the upgrade completed but there were errors".
It looks like there were a number of dependency problems with various packages - my question, do I need to fix this? Not sure how bad these errors are or what to do.
