Here is a very short guide what I would do directly after install.
Open a terminal and become root. (you type in su and hit enter and then give your root password)
Now the first thing would be to update the repository database:
It will now tell you there is 1 update available, glibc. This is an update that always must be installed before anything else so go ahead.
After installation it will re-spawn Entropy and continue asking to install the additional updates.
We stop here and first install the new entropy code with a trick so it doesn’t start pulling in huge dependency trees. Entropy does not need them to run anyway.
equo install entropy equo --relaxed
Once done we need to sort the mirrors. I noticed that on my test case it was set to a mirror in Australia. This is the other side of the globe and obviously not the best speedy connection I could get.
equo repo mirrorsort sabayon-weekly
Wait for it to test and then continue.
And there you have it.
