[gentoo-dev] You currently cannot smoothly upgrade a 4 months old Gentoo system

[Thomas Deutschmann]

Hi,



it is currently not possible to smoothly run a world upgrade on a 4 

months old system which doesn't even have a complicated package list:

When you try to upgrade world, it will fail with:

(no packages are manually set to a different Python version)







This is not about finding solution to upgrade the system (in this case 

it was enough to force PYTHON_TARGETS=python3_8 for portage). This is 

about raising awareness that Gentoo is a rolling distribution and that 

we guarantee users to be able to upgrade their system when they do world 

upgrades just once a year (remember: in my case the last world upgrade 

is just 4 months old!). If they cannot upgrade their system without 

manual intervention, we failed to do our job.



Situations like this will disqualify Gentoo for any professional 

environment like this will break automatic upgrades and you cannot roll 

individual fixes for each possible situation via CFM tools like Salt, 

Ansible, Puppet or Chef.



It would be very appreciated if everyone will pay more attention to this 

in future. We can do better. In most cases we can avoid problems like 

this by keeping older ebuilds around much longer for certain key 

packages to help with upgrades.



Thank you.
