Update warning in pamac: "parallel: Warning: $HOME not set. Using /tmp."

[cscs]

The topic concludes that the warning seen in pamac relates to rebuild-detector.

The warning comes from parallel which is pulled as a dependency of rebuild-detector.

After some pondering and history checking .. users finally realized it was not from pamac, and did not originate from the ISO, or calamares .. but was indeed from parallel which was not installed intentionally .. but was installed as a dependency when they explicitly installed rebuild-detector (for exactly the use-case described).

The mystery has been solved.

In which case the rebuild-detector is not as relevant as other tools which target AUR specifically.

If you say so. I dont use anything of the sort.
But maybe tell @philm .. because thats where the original suggestion is from.

Continuing the discussion from [Stable Update] 2023-06-04 - Kernels, Gnome 44.1, Plasma 5.27.5, Python 3.11, Toolchain, Firefox:

You will need to rebuild any AUR Python packages after the system update, that install files to site-packages or link to libpython3.10.so.

Print a list of of packages that have files in /usr/lib/python3.10/ :

pacman -Qoq /usr/lib/python3.10/

Rebuild them all at once:*

pamac build $(pacman -Qoq /usr/lib/python3.10)

• Note that if any fail to build, you’ll have to rebuild what’s remaining one or a few at a time.

Use rebuild-detector to see if anything else needs to be rebuilt:

checkrebuild
