Since a few updates ago, there are some packages that I can’t update. When I try, I get the following:

So, can I remove them, or do I have to rebuild them?
If rebuilding solves the problem then why remove. If it doesn’t → remove.
When I run pacman -Qoq /usr/lib/python3.9
I get
error: No package contains /usr/lib/python3.9
Actually these packages are not 3.9, so that’s why I’m confused.

That is for python3 packages that need to be rebuilded,
About your python2 packages, remove what you don’t need, and please check AURweb page
https://aur.archlinux.org/packages/python2-pycparser#comment-845512
If building the package fails for you, either build in a clean chroot or disable the tests, but at your own risk that the functionality will be faulty.
For building with makepkg and skipping check
makepkg --nocheck
I have been reading the solutions given in
https://aur.archlinux.org/packages/python2-pycparser#comment-845512
and the simplest one seems to be this one:
sudo fakepkg python2-pycparser (to have the package if new build still fails)
sudo pacman -Rdd python2-pycparser
yay -S python2-pycparser
The problem is that I don’t use yay, so my question is if I can change it to:
sudo fakepkg python2-pycparser (to have the package if new build still fails)
sudo pacman -Rdd python2-pycparser
sudo pamac build python2-pycparser
Is this okay?

Perhaps because Python 2 is a long way past EOL and does not get security updates?
@Franilustrador :
Would it be best to find out first what apps you have that depend on Python2?
When they have been upgraded, they should be using Python3.
Also, Arch/Manjaro is not guaranteed to be upgradable after a long break.
Maybe it will be easier to start again with a fresh install.

Yes, it does the same thing.
But no, don’t use sudo with pamac.
If it doesn’t work, it won’t do any permanent damage –
it only builds a package, and if it’s no good, either it won’t install or you can uninstall it.
[Disclaimer: I think these statements are true, but am not absolutely certain; use with care. ]
Well, this is what I’ve done, and so far there don’t seem to be any more problems. I have been able to update the other two packages, although I still need to investigate which application needs so manypython 2 packages. Actually, I think Displaycal only uses python 2, and I tried uninstalling it, although I don’t know what else to do or how to act to get rid of all the python 2 packages from AUR.
sudo pacman -Rdd python2-pycparser
sudo pamac build python2-pycparser

After refreshing my memory with (pacman - ArchWiki ) I tried :
‘pacman -Qd | grep python2’
‘pacman -Qe | grep python2’
‘pacman -Qs python2’
I think these show everything that is installed related to python2.
Try them and see what you get …

This is what I got :
$ pacman -Qd | grep python2
python2 2.7.18-5
python2-gobject 3.36.1-4
$ pacman -Qe | grep python2
[nothing]
$ pacman -Qd | grep gobject
gobject-introspection-runtime 1.70.0-5
python-gobject 3.42.0-3
There was nothing depending on ‘python2 -gobject’,
so I removed it recursively :
$ sudo pacman -Rsu python2-gobject
checking dependencies...
Packages (2) python2-2.7.18-5 python2-gobject-3.36.1-4
Total Removed Size: 78.04 MiB
:: Do you want to remove these packages? [Y/n] y
...
The fact that it offered to remove python2 as well meant
that there was nothing else depending on python2, so I hit ‘y’.
Now my machine is free of ancient python2,
which should have died 10 years ago.
@Franilustrador :
Have you successfully updated everything else on your system?
If so, then persist with weeding out python2.
If not, then consider doing a fresh install, as the Arch/Manjaro rolling release system can get into a state that is not automatically upgradable if you leave it for too long between upgrades. You might succed with python2, then find that other things will not upgrade.
