Python updates

[LIsLinuxIsSogood]

I am running a stable systemd profile for a gentoo print server with very minimal installation. It had not been updated in approximately 6 months maybe and I was expecting some package conflicts as usual. I am stuck on some python thing that I noticed is probably because I am on a version of python that is no longer in the main repo tree.

For smaller packages I would probably remove them and then rebuild them, but with this one I think many currently installed packages have it as a dependency,

Is this situation a good one for emerge -1u and then I can revdep-rebuild maybe afterwards?
The only other way I know is to start f*cking with individual packages and masking those. It is possible I could just rebuild everything but that would take too long to do.
Is Python2 still needed or useful to the operating system too?

Please show us your situation, with full context including your emerge command. No one can tell you anything before that happens.

Is this a stale dependency from a previous upgrade, probably yes, which in theory the -e flag should handle by rebuilding all packages, for this situation that seems too extreme to have to rebuild over 600 packages!!!

I could just emerge --unmerge python and then what...rebuild the reverse dependencies against a new version of python in the repository?


EDIT:
Here is what I get when I try to remove it...which I assume means it will cause Portage to stop working if I remove it so that is not good.

Code: Select all

HPNotebook /home/jonny # emerge --unmerge '=dev-lang/python-3.6.10' --ask
 * This action can remove important packages! In order to be safer, use
 * `emerge -pv --depclean <atom>` to check for reverse dependencies before
 * removing packages.

>>> These are the packages that would be unmerged:
 * Not unmerging package dev-lang/python-3.6.10 since there is no valid reason
 * for Portage to unmerge currently used Python interpreter.

EDIT:
I am very confused about the state of dev-libs/gobject-introspection...why do I have a higher version of this installed than what is currently in the gentoo repository? I only ever built all the packages on this system from the main repo, with the only expection being some printer drivers.

There is no error in that output. You have 61 upgrades, 10 reinstalls caused by USE flag changes, and one conflict that will resolve istelf (small 'b') with the simultaneous upgrade of dev-libs/gobject-introspection and dev-libs/gobject-introspection-common...

It looks available to me.

According to the content of the pastebin, you are upgrading, not downgrading, gobject-introspection. If I had to guess, I would say that the eix database you used to generate the output I quoted is out of date, and thus giving you incorrect information. I like eix for its summary data, but in this case you might be better served by emerge --pretend --verbose --nodeps dev-libs/gobject-introspection dev-libs/gobject-introspection-common.

Why is this not automatically happening during the larger set of upgrades?

Is this a problem?

UPDATE:
I tried a different upgrade command using emerge -udN @world upgrade seemed to allow the building to happen

Should I mark as solved yet?

[mlybarger]

i had similar issues. googleing took me to this post. further searching let me to fix my world file. i used the checkworldfile script referenced on this post

finally, i was able to do an upgrade: emerge -uD --newuse @world

Why isn't this function included in emaint --check world?
