Public bug reported:
When trying to upgrade my Ubuntu 14.04.5 LTS server using the command
sudo apt-get dist-upgrade, the upgrade consistently failed while trying
to upgrade libidn11 to version 1.28-1ubuntu2.2 with the following error
message:
unable to install (supposed) new info file
`/var/lib/dpkg/tmp.ci/postrm': Is a directory
I determined that instead of being a script,
/var/lib/dpkg/info/libidn11:amd64.postrm was in fact a directory! It
contained two kernel modules, llc.ko and llc2.lo. I will attach the two
files.
To get the package to install and the upgrade operation to proceed, I
renamed /var/lib/dpkg/info/libidn11:amd64.postrm to
/var/lib/dpkg/info/libidn11:amd64.postrm.bak, after which a renewed
dist-upgrade proceeded without any warnings or errors.
After the installation /var/lib/dpkg/info/libidn11:amd64.postrm once
again existed, and is now a script, as expected.
What gives? Is this a bug in either this or the previous version of
libidn? Is it now correctly installed? Was I hacked (I get a bit nervous
when executable files spontaneously appear in random places)? I scanned
the two files with virustotal.com, and it found nothing, but I don't
think that means much.
