The slot conflict(s) shown above involve package(s) which may need to !!! be rebuilt in order to solve the conflict(s). However, the following !!! package(s) cannot be rebuilt for the reason(s) shown: (dev-lang/python-3.7.7-r2:3.7/3.7m::gentoo, installed): ebuild is masked or unavailable (sys-apps/man-db-2.8.7:0/0::gentoo, installed): ebuild is masked or unavailable (dev-lang/python-2.7.18:2.7/2.7::gentoo, installed): ebuild is masked or unavailable It may be possible to solve this problem by using package.mask to prevent one of those packages from being selected. However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically.

The following installed packages are masked: - sys-libs/glibc-2.30-r8::gentoo (masked by: package.mask) /usr/portage/profiles/package.mask: # Michał Górny , Andreas K. Hüttel , # Matthias Maier (2017-05-21 and later updates) # These old versions of toolchain packages (binutils, gcc, glibc) are no # longer officially supported and are not suitable for general use. Using # these packages can result in build failures (and possible breakage) for # many packages, and may leave your system vulnerable to known security # exploits. # If you still use one of these old toolchain packages, please upgrade (and # switch the compiler / the binutils) ASAP. If you need them for a specific # (isolated) use case, feel free to unmask them on your system.
