Bug Description

The latest package available on testing (4.9-20140213-0ubuntu1) is missing the /lib/x86_64-linux-gnu/libgcc_s.so.1 file.
This causes apt-get to break immediately after apt-get upgrading.
The package is unusually small:
-rw-r--r-- 1 root root 1286 Feb 14 09:38 /var/cache/apt/archives/libgcc1_1%3a4.9-20140213-0ubuntu1_amd64.deb
at only just over 1KB
The version from packages.ubuntu.com for testing shows as 4.8.2 still, downloading this and dpkg-i'ing the package fixes the issue (until you apt-get update/upgrade again).
The old version of the file (which is 30+ times larger):
-rw-r--r-- 1 root root 37520 Feb 12 02:38 libgcc1_4.8.2-15ubuntu3_amd64.deb

If you're lucky, libgcc1_4.8.2-15ubuntu3_amd64.deb is probably lying around in /var/cache/apt/archives, sdo you can dpkg -i from here... (unless you cleaned files, then you'll need another computer to get the file !!!)

Hi Franck,
Thanks, but unfortunately I apt-get clean after each upgrade, however I just wget'ed the file from the ubuntu package site, which temporarily sorted things until the package is fixed.
Thanks,
Tom.

Just for anyone who needs an emergency fix:

wget http://de.archive.ubuntu.com/ubuntu/pool/main/g/gcc-4.8/libgcc1_4.8.2-15ubuntu3_amd64.deb
dpkg -i libgcc1_4.8.2-15ubuntu3_amd64.deb

Hope that helps.
