I don't know what happened before, but now I've got this kind of error in Ubuntu 14.04 on my notebook whenever I try to install any package/program though terminal or software center:
configuring tzdata can't open /usr/share/debconf/confmodule dpkg: error processing package tzdata(--configure): post-installation returned error code 2
I checked this folder:
/usr/share/debconf and found out that it contains nothing, that's why it cant be opened.
dir in terminal while in this folder, and it output nothing at all.
I tried reinstalling, deleting and checking this package, and even clearing cache of apt-get, but it didn't work nor fix the problem and raised the same error.
