Hi Aleksej,
Thanks for fixing the "get" problem related to this bug.
Update, reinstall, remove needs your attention :)
This bug only appears if the packages tazpkg chooses in error are installed.
The method used to determine installed packages is misinterpreting these names.
These are the packages on my system but there may be others:
With xz installed, user can't reinstall, remove or update lzma
With libcomerr3 installed, user can't reinstall, remove or update libcomerr
With freetype-infinality installed, user can't reinstall, remove,or update freetype
With yad-html installed, user can't reinstall,remove or update yad
With libsasl-modules installed, user can't reinstall or remove libsasl-without-ldap
With mesa-wayland installed, user can't reinstall, remove, update libglw-mesa or libegl-mesa
Update is a forced reinstall of existing package with new build or version.
You should be able to reproduce the problem.
Install xz:
tazpkg -gi xz
Remove lzma:
