After upgrading from 14.04 to 16.04 Lyx has trouble opening documents I created or creating new documents from templates like
dinbrief where it says that some files are corrupted, the
basic module that is required or some other files or dependencies could not be found.
I reinstalled Ubuntu instead of doing an upgrade and restored a backup of the home directory. I made a list of packages that were installed and only picked the packages and applications I still use. I have been doing this for a few years now for LTS and non-LTS releases and I'm confident that I didn't miss something important, basically installing the lyx meta package and some recommended packages should give me a working setup.
Since it said the files are corrupted – 😱 – I tried reinstalling the related Lyx and Texlive packages that
apt remove auto completion offered me but without success. How can I solve this problem? Are my files or the installation corrupted?
