Comment 22 for bug 191327

I would like to add an observation even though a cause of the problem has been listed here.
I have recently updated 5 machines running Kubuntu 7.10 but only 2 of them had the severe problem that required remediation, one running the x86 kernel the other the x86_64 kernel. (and all machines with 'Canada' locale).
I noticed something irregular when looking at the contents of the directory of the first machine that broke:
/var/cache/apt/archives.
Normally every package has a unique identifier, even though some apparently are installed in two parts, and have a '-1' and '-2' designation.
However, for the KDE English language packs (that is, 'language-pack-kde-en' and 'language-pack-kde-base') there were duplicate entries, one with the 2007 time stamp and one with the newer 2008 time stamp.
When I rescued KDE (working through a different window manager), it appears that running 'apt-get remove language-pack-kde-en' cleared out the older (2007) version of the 2 language packs while leaving the 2008 version.
So there may (at least in some cases) be more to this bug then what is described in Martin Pitt's post above.
