Arch Linux User Repository

Thank you both @willemw and @Kr1ss. Didn't mean to turn this into a support thread but that helped explain what is happening.

Yes, -Sy is an update (of only the mirrorlist and the package list), not a system upgrade.

Hi @willemw pls excuse me for interfering w/ the thread unaskedly. I'd like to point out to @DavidMLS that they should rather do -S or -Syu to install (resp. upgrade the system and install) a package.

-Sy can (and eventually will) lead to a partially upgraded system, which might likely have caused this issue in the first place.

The causalities are described in this wiki paragraph.

Cheers !

@DavidMLS: Ok, I see what the problem is: your python-greenlet is not up-to-date. Do a system upgrade. python-greenlet should then be 0.4.16-1.

python-greenlet is an indirect dependency of castero-git.

It is normal that the castero-git version gets updated. The version is calculated each time you install the package (see pkgver() in the PKGBUILD file).

@willemw please excuse my ignorance but I've tried doing the following:

yay -Rns castero-git
rm -rf ~/.cache/yay/castero-git
yay -Sy castero-git

and I still had the same problem.

I also tried to do the following:

makepkg
sudo pacman -U ...

What I found strange is that although in your PKGBUILD, you have pkgver=0.8.0.r45.g29f42b1, the pkgver got changed after running makepkg to something like pkgver=0.8.0.r47...

I am a beginner at packaging in Arch and so don't fully understand what's going on.

I managed to get it working by installing castero manually from the instructions here but I would like to understand why using your package doesn't work as I see that it's doing pretty much the same thing that I did manually.

@DavidMLS: I cannot find any reference to greenlet in the source files. You may need to rebuild this package.

I think this now needs greenlet

@rien333: Thanks. Updated.

I think this needs to have python-grequests in its dependencies:

$ castero

Codfractal: this is a VCS (devel) package. That means it is up to you, as a user, to update the package by reinstalling the package or, in most cases, by passing the --devel flag to your AUR helper when you update.
