Bug#387928: Bug #387928: fontconfig: Cannot write cache files
Pablo Di Noto
In my case, the problem arises when installing package ttf-opensymbol
(as dependency to OpenOffice 2.0.4-5 packages).
fc-cache fails:

Seems like fc-cache does not write cache if the destination directory
"seems newer" that now, and fails.
That gives debconf a reason to fail, and the entire install stops.
Simply touching the directories where fc-cache refuses to write its
cache files fixes the problem.

In my case, the time difference comes from the fact the bootstrapping
machine has correct timezone, while the new system did not.
Perhaps fc-cache should exit with non-error code in this case?
HTH!
