Why would you want to install both libjpeg-progs and libjpeg-turbo-progs? "apt-cache depends libjpeg-progs" tells they conflict and replace each other.
I noticed similar issue after upgrading from Trusty to Xenial. Both packages were installed. I resolved that by purging libjpeg-progs. I did not want to purge libjpeg-turbo-progs, because jhead depends on it and I wanted to keep it. I had no problem by purging libjpeg-progs by apt, but some have had and here is related post: https://askubuntu.com/q/766929/21005 BTW what is libjpeg8-empty? $ apt-cache policy libjpeg8-empty N: Unable to locate package libjpeg8-empty I see similar bugs Bug #1576010 Bug #1559754 Bug #1576937 Bug #1571195 Bug #1527455 Bug #1516242 ** Tags added: package-conflict -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1550124 Title: package libjpeg-progs 8c-2ubuntu8 failed to install/upgrade: trying to overwrite '/usr/bin/rdjpgcom', which is also in package libjpeg-turbo- progs 1.4.2-0ubuntu1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libjpeg8-empty/+bug/1550124/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
