There are 2 ways to upgrade Gentoo’s profile: whether by using the program eselect, or by manual linking.
Firstly the portage tree needs to be updated to get the latest profile list by running the following command;
$ sudo emerge --sync
The following example is to update using eselect;
$ sudo eselect profile list $ sudo eselect profile set <number>
Where number is the number of the favored profile from the list.
To manually update the profile, delete the softlink and create a new link to the intended profile as the following (be sure not to add / at the end of /etc/make.profile)
$ sudo rm /etc/make.profile $ sudo ln -s /usr/portage/profiles/<profile of choice> /etc/make.profile
Optionally, in the end, you might want to upgrade the system using the new profile;
$ sudo emerge --sync $ sudo emerge --update --newuse --deep world
