Profile Upgrade 23.0 on an outdated system

Dear community,

I somehow forgot time for one machine which I didn't use frequently in the last 1-1.5 years, which I want to migrate and update now.
Immediately the news to upgrade to 23.0 appeared when I wanted to update my system, so I read that consequently and planned to follow it accordingly; unfortunately I didn't.

I tried to follow the initial recommendation to fully upgrade beforehand the migration to 23.0; Portaged only showed 10-15 packages to upgrade on the old profile but some little conflicts, so it wasn't able to run. Than I checked my minimum glibc version as in the news since it stated this is a minimum necessity. My glibc version installed was okay for that, so I immediately followed the next migration steps as I believed emerge -e can take care about outstanding updates too.

I selected a merged-usr profile, however, Portage told me my partition layout suggests I am on split-usr and I should change to a split-usr profile. Since the profile 23.0 upgrade news item suggests to firstly upgrade to 23.0 and only then to migrate to merged-usr, I changed to the split-usr profile and planned to check on the merged-usr situation later on.

I am now on the emerge -e for the profile 23.0, which only brings ~12 items and a few circular dependencies. I un-emerged that circular dependencies; this way I mostly was able to resolve dependency issues in the last decade (maybe that is unelegant, but it worked for me).

Do I have a chance to update and migrate to 23.0 now, or should I change back to the older profile before?

That is my emerge --info and emerge update output:
emerge --info
emerge -auDU --with-bdeps=y --keep-going --backtrack=200 -j2 @world

I am grateful for any advice!

Many thanks and greetings,

Since migration to 23.0 involves emerge --emptytree (it took me 6,5 hours on decent hardware for ~1500 packages, around two thirds of which were binary packages from the binhost), it would be wiser to just salvage your /etc/portage files and user data and perform a new installation. The portage binhost will be of great help.

It's just not worth the trouble, time and even electricity wasted.

On the other hand if you're in for the fun of it, this circular dependency is introduced by rust slotting. Maybe look up the threads related to that for clues on how to solve it.

p.s. the 12 packages emerge output you've posted above is not from emerge -e. You've forgotten the -e.

Best Regards,
Georgi

How much do you want to learn about portage?

What logrusx said will be fastest.
Going back to your old profile and updating in say six month steps, until you are current, will take longer and teach you more. :)

If you want to do the updates, make yourself some snapshots from git or use the squashfs snapshots provided by Gentoo.

Of your revert, be careful to avid the 23 binhost. In don't know what's the state of the 17.1 binhost, but you should not mix one binhost with another profile.

Also you would be better if you backup your settings either way.

Add i mentioned in my edits, which you might have missed this is not the empty tree emerge output.

Georgi

Thanks for the hints!
I know my upgrade try was without -e because a pure -e had a very similar output. Therefore, I tried to update without -e first. Neither of it worked out.

The squasfs snapshots are at https://distfiles.gentoo.org/snapshots/squashfs/
Pick one slightly ahead of your last full update and do a full update.
Don't forget to update the kernel and act on any news items.

Now choose a newer snapshot, rinse and repeat.

If you get blockers you have jumped forward too far.
Step sizes of between 6 and 12 months will mostly work.
If you want to use the binhost, that works to save time, as long as settings match.
You need the old binhost though.

What you are doing is going through the updates you missed in as big a steps as will work.

"Portage 3.0.56"
first, before merging packages, please updating the package manager -> sys-apps/portage
