my Ubuntu's graphics output had broken, and I had to reinstall it. To keep my data and settings, I just reinstalled it from a CD over the old system.
Everything went smooth, apart from the fact that I get errors on every update:
stan@stan-ThinkPad-T530:/var/lib/dpkg/info$ sudo apt-get autoremove Reading package lists... Done Building dependency tree Reading state information... Done 0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade. 1 not fully installed or removed. After this operation, 0 B of additional disk space will be used. Setting up fontconfig (2.11.1-0ubuntu6) ... Regenerating fonts cache... failed. See /var/log/fontconfig.log for more information. dpkg: error processing package fontconfig (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: fontconfig E: Sub-process /usr/bin/dpkg returned an error code (1)
There are two (possibly linked?) issues that are bothering me:
1 not fully installed or removed.in the 6th line. It does not tell me which package is not fully installed or removed, and I have no clue how to find it out.
The error caused by
fontconfigin the last line. I am getting this error after each update, since
fontconfigis run each time.
cat /var/log/fontconfig.log gives me the following:
/usr/share/fonts: caching, new cache contents: 0 fonts, 4 dirs ... a lot of lines with various fonts ... /usr/share/fonts/type1/gsfonts: caching, new cache contents: 35 fonts, 0 dirs /usr/share/fonts/type1/mathml: caching, new cache contents: 1 fonts, 0 dirs /usr/local/share/fonts: caching, new cache contents: 0 fonts, 0 dirs /.local/share/fonts: skipping, no such directory Re-scanning /usr/share/fonts: fc-cache: symbol lookup error: fc-cache: undefined symbol: FcDirCacheRescan
I've already spent so much time looking for a possible solution, and tried the following commands which were suggested here and there, among others
sudo dpkg --configure -a sudo apt-get clean sudo apt-get dist-upgrade
but all in vain. Any debugging help would be highly appreciated!
Shutupshare suggested doing
apt-get install --reinstall libfontconfig1 libfontconfig1-dev libfontconfig1-dbg, this gives the following:
stan@stan-ThinkPad-T530:~$ sudo apt-get install --reinstall libfontconfig1 libfontconfig1-dev libfontconfig1-dbg Reading package lists... Done Building dependency tree Reading state information... Done Reinstallation of libfontconfig1 is not possible, it cannot be downloaded. Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies. libfontconfig1-dbg : Depends: libfontconfig1 (= 2.11.0-0ubuntu4) but 2.11.0-0ubuntu4.1 is to be installed libfontconfig1-dev : Depends: libfontconfig1 (= 2.11.0-0ubuntu4) but 2.11.0-0ubuntu4.1 is to be installed Depends: libfreetype6-dev (>= 2.1.7) but it is not going to be installed E: Unable to correct problems, you have held broken packages.
hold (gives nothing)
stan@stan-ThinkPad-T530:~$ sudo dpkg --get-selections | grep hold
stan@stan-ThinkPad-T530:~$ sudo dpkg --get-selections|grep purge rsyslog purge
stan@stan-ThinkPad-T530:~$ sudo dpkg --get-selections|grep deinstall libcap2:i386 deinstall libcgmanager0:i386 deinstall libepoxy0 deinstall libffi6:i386 deinstall libglib2.0-0:i386 deinstall libllvm3.5:amd64 deinstall libpython2.7-minimal:i386 deinstall libsystemd-daemon0:i386 deinstall libudev1:i386 deinstall
The rest has the status
