Hi,
I´m trying to upgrade portage because I´m getting a message that it
needs to be able to work with EAPI 6 packages and can only do EAPI 5.
I´m running into merge conflicts when trying to update portage, and
apparently one of the packages (dev-python/cryptography) I could try
to update first to be able to update portage requires a version of
portage that can handle EAPI 6 packages.
Try the other suggestions first -- but as a last resort -- you can
always grab a new stage3 that should contain an updated version of
portage and simply overwrite the portage files on your machine. A
quickpkg from another Gentoo machine (or the liveCD?) would also work.
I´m trying to update a production server here. If I overwrite the whole
system, who knows what might break. I can take it down for a few
hours in the evening unless I want to work over night, which is not
really an option.
There must be a way to update a Gentoo installation without breaking it.
As wonderful as it otherwise is, updating Gentoo is always a nightmare
which
makes me very seriously consider not to use it anymore. Updating needs to
be easy and flawless and not something you always run into weird issues
with.
When I run gentoo as a critical server, I always have a second, redundant
system pretty much identical, on stanby. I upgrade the stanby first and run it
a few days, then the production system. It makes reliability extraordinarily
high. But, the again, I do a version of the
same thing with all critical systems, or I do not work on them.
This isn´t really an option because the problem is with the updating
itself, not with something not working after the update has been
performed.
Granted,
as successful consultant, I have that luxury.
It´s time consuming ...
Did they recently make a new liveDVD?
A few months ago.

Cool, the old one was really getting old.
Perhaps a better solution is to make a stage-4, of your current gentoo
(production) system, verify that the stage-4 works by using it to install a
similar system, test and deploy. And then hack or fix the production system,
during the daytime, at your leisure?
Stage-4 gentoo systems have been around a long time. Documentation varies and
most have their own 'home spun' approach to stage-4 replicant systems, backups
etc etc.
It might be a way to try and see if upgrading from older states step by
step until the installation is current would work. But how do I do that?
Considering how much time and effort it might take and that the update
problems aren´t going to go away, I have to wonder whether it´s better to
install Debian or Centos on another machine and to migrate the services.
Doing so would allow to make some improvements and to consolidate several
physical machines into one.
Either way, it sucks.
