Re: [SOLVED] python2-mutagen upgrade breaks mutagen, required by nicotine+

I don't know enough about mutagen to know if python-mutagen or python2-mutagen should provide it, but clearly there is a packaging bug as nicotine+ in the repos depends on a package that does not exist and is not provided by any package in the repos.  I have none of the above mentioned packages installed and nicotine+ cannot be installed:

$ pacman -S nicotine+
resolving dependencies...
warning: cannot resolve "mutagen", a dependency of "nicotine+"
:: The following package cannot be upgraded due to unresolvable dependencies:

:: Do you want to skip the above package for this upgrade? [y/N] y
looking for conflicting packages...
 there is nothing to do

I'd report this as a bug against the nicotine+ package first.  It could be reassigned to the python(2)-mutagen packages if they should actually still provide the virtual package 'mutagen'.

Multi-init booting with apg Openrc and systemd coexisting
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them
