I probably corrupted my mysql configuration when I tried to install it (again) using the ubuntu package manager (stuck in the middle, because of the required interaction for which there is no screen, (package manager should really give a warning that mysql must be installed via the terminal!)).
Maybe already before, but at least since then, I'm stuck with this error (partly in Dutch):
Fouten gevonden tijdens verwerken van:
mysql-client-5.6
E: Sub-process /usr/bin/dpkg returned an error code (1)
I get the error when I try to install, as well as when I try to remove the package or any other mysql component. I found many solutions on the internet that worked for others, but failed in my case. I already did the following (in advised order, which may be different from the list below):
I could not find a listing of all the files related to mysql, to manually delete the lot.
Any suggestion what else I might try (except reinstalling Ubuntu entirely)?
apt-get install -f
