Title:
apt removes package when packagename ends with -
Status in apt package in Ubuntu:
Confirmed
Bug description:
It turns out that if you mess up (like in your system automation
setup) - and ask for installing a package named perl-byacc- (where you
wanted to install perl-byacc-subname) - apt just chooses to remove
perl-byacc.. even if perl-byacc is not installed - it returns 0 -
meaning everything seems okay :(
