Replace '0ubuntu1~12.04' packages with '16ubuntu6'

Question

I recently upgraded my server from Ubuntu 12.04 to 14.10. I had installed GCC 4.9 (4.9.2 apparently) before the upgrade and today I wanted to install gcc-4.9-multilib, but apt-get gave me:

gcc-4.9-multilib : Depends: gcc-4.9 (= 4.9.1-16ubuntu6) but 4.9.2-0ubuntu1~12.04 is to be installed

So I removed gcc-4.9 and wanted to reinstall it, but the same game happens with gcc-4.9-base:

 gcc-4.9 : Depends: cpp-4.9 (= 4.9.1-16ubuntu6) but 4.9.2-0ubuntu1~12.04 is to be installed
           Depends: gcc-4.9-base (= 4.9.1-16ubuntu6) but 4.9.2-0ubuntu1~12.04 is to be installed

cpp-4.9 I could remove, but removing gcc-4.9-base would leave not much more than the kernel behind I guess...

[ Too long, click for paste ]

I also tried using aptitude to remove 4.9.2-0ubuntu1~12.04 and installing 4.9.1-16ubuntu6, but when I try to apply the selected changes, it gives me:

Some packages were broken and have been fixed:
Keep the following packages at their current version:
gcc-4.9-base [4.9.2-0ubuntu1~12.04 (now)]

So how do I get rid of that 12.04 stuff without removing my entire operating system?

Have you tried this?http://askubuntu.com/questions/140246/how-do-i-resolve-unmet-dependencies-after-adding-a-ppa — g_p, Jan 19 '15 at 04:29
what if you try sudo apt-get install gcc-4.9=4.9.1-16ubuntu6 — g_p, Jan 21 '15 at 01:58
Run sudo rm /var/cache/apt/pkgcache.bin followed by sudo apt-get update — g_p, Jan 21 '15 at 15:34
OK. I have no idea why it is happening. Can you post the output of sudo apt-get update? — g_p, Jan 22 '15 at 05:48
Are you sure your /etc/apt/sources.list.d directory is empty, becouse the Sources.list you have provided has no entry for pkg.jenkins-ci.org which I can see in the apt-get update output? — g_p, Jan 22 '15 at 10:47
Try sudo apt-get install gcc-4.9-base=4.9.1-16ubuntu6. Also delete few unnecessary comment as it is getting lengthy. — g_p, Jan 22 '15 at 18:18

I had the same problem. I tried downgrading all of the gcc packages without success because apt-get couldn't find the right version of libgcc1, although apt-cache told me it did know it:

$ sudo apt-get install  libgcc1=4.9.1-16ubuntu6
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Version '4.9.1-16ubuntu6' for 'libgcc1' was not found

I downloaded libgcc1_4.9.1-16ubuntu6_i386.deb and /var/cache/apt/archives/libgcc1_4.9.1-16ubuntu6_amd64.deb manually from the website, and was able to downgrade with this command:

/path/to/libgcc1_4.9.1-16ubuntu6_amd64.deb \
/path/to/libgcc1_4.9.1-16ubuntu6_i386.deb

You may need fewer entries there - if apt tells you it's going to install 'new' packages, rather than downgrading existing ones, you might be able to remove those ones.

Replace '0ubuntu1~12.04' packages with '16ubuntu6'
