Checking glibc installed version

[arodulfo]

Dear all,

I need to check my glibc version is 2.15 or later. After reading this link (http://ubuntuforums.org/showthread.php?t=2088459), I got the following results:


~$dpkg-query -l glibc* | grep un

un glibc-2.13-1
un glibc-doc


When looking for libc6 in synaptic, all the versions shown say 2.15-0ubuntu10.7. :confused:

If I pay attention to the first one, I slhould upgrade my glibc to the latest available version.
If I pay attention to synaptic, which I am tempted to do, my current system is ok and need no glibc upgrade.

Which one is correct?

Thanks a lot for being there! Kind regards. ):P

Which version of Ubuntu you using?
My 14.04 install shows glibc of 2.19 -- Latest glibc released is 2.20 on 2014-09-07.

I think you have discovered a bug in an old version in 12.04 (wrong release number).

Different releases of Ubuntu use appropriately released version of libc6 for their time.

If you are updating libc6 regularly from the Ubuntu repositories (instead of a PPA or someplace else), then you should be safe and stable.
