Here is the second problem I run into, once solved Proble updating Gentoo
Trying again with this command.
sudo emerge --update --deep -p world
I got this
!!! Multiple package instances within a single package slot have been pulled !!! into the dependency graph, resulting in a slot conflict: www-client/mozilla-firefox:0 ('ebuild', '/', 'www-client/mozilla-firefox-126.96.36.199', 'merge') pulled in by =www-client/mozilla-firefox-2* required by ('installed', '/', 'gnome-extra/yelp-2.22.1-r2', 'nomerge') (and 1 more) ('ebuild', '/', 'www-client/mozilla-firefox-3.0.6', 'merge') pulled in by www-client/mozilla-firefox required by world 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. For more information, see MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook.
Solve it adding to your /etc/make.conf in the USE line this at the end
And then run
sudo emerge --update --deep --newuse world
And it will work.
I found the solution in the Gentoo Mail Archive thanks to them.
