Created attachment 722332 [details] emerge --info imho "depclean" emerge action should recognize that the referencing packages are given on the commandline (ie candidates to be removed) or that they are referencing each other and treat the requirements as solved or ignore them. the text leading to this bug was: - dev-python/traceback2-1.4.0-r1::gentoo (masked by: package.mask) /usr/portage/profiles/package.mask: # Michał Górny <mgorny@gentoo.org> (2021-07-06) # Various Python 2-specific backports.
