[gentoo-user] Upgrade an old system

[gentoo-user] Upgrade an old system

[thelma]

I'm having similar problem as "n952162" upgrading an old (last updated
1.8-year ago)
It sync OK, updated the profile.

Looking instruction on this page:
https://wiki.gentoo.org/wiki/Upgrading_Gentoo

root #mv /usr/portage /usr/portage.latest
root #tar xjpf /path/to/portage-20090720.tar.bz2 -C /usr
root #emerge --update --oneshot portage

but that portage "portage-20090720.tar.bz2" seems old; what is the
latest one?

They're generated every day, so pick your poison. Notice it mentions
updating the portage tree 3-4 months at a time, so just pick some
dates at reasonable intervals from your starting point.

Looking at this directory:
https://github.com/gentoo/portage/releases/tag/portage-3.0.12

file: portage-portage-3.0.12.tar.gz   has totally different structure
If I run: tar xzf portage-portage-3.0.12.tar.gz -C /usr
it will create directory /usr/portage-portage-3.0.12

emerge --update --oneshot portage
can not fine it as it is looking for /usr/portage

I've done a similar update recently, it's definitely possible if you
know what you're doing. A few things:

First, you need to update portage. To do so, you'll need to manually
downgrade the portage ebuild from EAPI 7 to EAPI 6 (simply change the
number in the ebuild). First, emerge it without rsync-verify. Once you
have portage up to date, it'll support EAPI 7 and life'll be easier. You
can then reemerge it with rsync-verify, as the EAPI 7 dependencies will
be installable this time.

Then, I'd recommend upgrading the toolchain (binutils, gcc, glibc),
otherwise you might run into compilation issues.

After that, you can update packages. For big updates like this, I like
to do it by chunks as it's easier (and it makes reading the emerge plan
less painful). Like all the perl packages, then all the python packages,
and so on. For that, the "emerge by path" feature is convenient; for
example to update python packages:
emerge -au /usr/lib/python3.7

In case force-unmerging python modules makes the update easier
(resolving blocks), you can do so. That's actually safe to do, portage
will still be able to emerge packages. Python itself (the interpreter)
is the only hard dependency of portage. 

Hope this helps, and good luck with your update!

That is a release of the portage *application*, you need snapshots of
the portage *tree*.

I could find some a year old here:
https://mirrors.sohu.com/gentoo/snapshots/

You might need to look for even older ones, but worth a try.

Moving forward like a snail.
Unmerged portage to local directory and running:
./portage-portage-3.0.12/bin/emerge -1 portage

gives me two blockers:
[blocks B      ] <app-portage/gentoolkit-0.4.6 ("<app-portage/gentoolkit-0.4.6" is blocking sys-apps/portage-3.0.9)
[blocks B      ] <=dev-lang/python-2.7.18-r3:2.7 ("<=dev-lang/python-2.7.18-r3:2.7" is blocking dev-lang/python-exec-2.4.6-r2)

I can remove app-portage/gentoolkit but is it safe to remove:
dev-lang/python-2.7.18-r3:2.7

Probably not. It looks like you need to update python, try

emerge -1a portage python:2.7

Or simply

emerge -1ua @system

iirc, gentoolkit is an add-on that helps with portage. As such it would 
be safe to remove ...

Read the handbook and see if it *recommends* installing gentoolkit. If 
it does (as I seem to remember), it isn't *necessary* and can be removed.

If I were youe, I'd just reinstall after 1.8 years. Updating is going
to take way, way more work.

I was thinking the same thing. But I'll try first if its possible to
upgrade.

go to the http://www.gentoo.org/downloads/mirrors/ and find a mirror, 
the snapshots will have lastest portage.

Like

https://gentoo.osuosl.org/snapshots/portage-latest.tar.bz2

It always update.

And update a old system may cause a log of problems, be careful.
