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:

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.

Since this is a -git package, just rebuild and you should be good to go @Codfractal ;)

Cheers !

@willemw castero 8.0 has been released a few days ago, could you please update the package ? Many thanks :)

@MagicAndWires: I think upstream simply needs to stop requiring python-vlc, the reasoning behind keeping it seems a bit silly imo (see https://github.com/xgi/castero/issues/29). If you're okay in python, I would recommend just trying to get a PR in that makes all vlc stuff completely optional, instead of putting in effort on this PKGBUILD. If I find time this week and dig the castero app, I might try and implement said PR myself.

@MagicAndWires:

Thanks. Updated the upstream URL.

In general, one way to prevent vlc from being installed on your system is to create and install an empty/dummy package which "provides" and "conflicts" with "vlc". The advantage is that this will work not only with castero-git but with any package that has vlc as a dependency.

Edit: note castero-git also depends on python-vlc.

Also, please update the upstream url to the github project page as the current link has been removed.

Note that this package technically only needs the mpv or vlc media player.

Considering vlc is a quite heavy-duty (and in imho bloated) player to simply play some audio files users who might not want to use this particular player can safely remove the vlc and it specific dependencies with the --nodeps and --recursive flags. python-vlc is necessary for castero (which unfortunately has vlc as its makedepend) so for now it is necessary to keep that package and manually remove vlc at every install.

I'll test some things as to whether the software to run properly, or whether it's just due to the python-setup configuration, and depending on the results I'll try to make a mpv-only package.

@cheezsteak: Thanks. Fixed and updated.

I was only able to run castero after changing dependency python-pympv to python-mpv. If someone else can confirm that bug it should be updated. Thank you.

@Kyatik: Not out-of-date. You need to reinstall (or update with --devel) to update the package.

@Kr1ss: Thanks. Updated.

Hi, thx for providing this package @willemw !

Could u pls add dependencies to python-pympv and python-cjkwrap, since castero wouldn't run without them.

EDIT: Thank you for updating so quickly !
