Problem with case-sensitive chroot names in DNF5 copr plugin

[FrostyX]

Reported on Matrix today.
Enabling a Copr project via DNF5 didn't work because of the capital F in the Fedora-41-aarch64 chroot.

dnf copr enable ngompa/fedora-asahi-dev
Chroot not found in the given Copr project (Fedora-41-aarch64).
You can choose one of the available chroots explicitly:
...
fedora-41-aarch64
...

I am not sure how the capitalized chroot name came from. A workaround was

dnf copr enable ngompa/fedora-asahi-dev fedora-41-aarch64

I cannot reproduce on x86_64 on F41. May be aarch64 specific.

I tried in fedora-41-aarch64:

<mock-chroot> sh-5.2# python3
Python 3.13.0 (main, Oct  8 2024, 00:00:00) [GCC 14.2.1 20240912 (Red Hat 14.2.1-3)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import distro
>>> distro.id()
'fedora'

And it is correct too. I probably wouldn't search for the cause of the problem and only .lower() the chroot name

It's probably Asahi related? I'm on Asahi too and noticed the same thing

[FrostyX]

Thank you very much for the confirmation @PaddiM8. We were suspecting that and wanted to ask some Asahi users that we know, to test this.

Can you please paste the output of these two commands?

python3 -c "import distro; print(distro.id())"
cat /etc/os-release |grep ID |grep -i fedora

[jannau]

python3 -c "import distro; print(distro.id())"
fedora-asahi-remix

cat /etc/os-release |grep ID |grep -i fedora
ID=fedora-asahi-remix
ID_LIKE=fedora

[PaddiM8]

~ ❯ python3 -c "import distro; print(distro.id())"
fedora-asahi-remix
~ ❯ cat /etc/os-release |grep ID |grep -i fedora
~ ❯

Upgraded from 39 to 41 just before noticing this btw

Thank you very much @jannau and @PaddiM8.

I am still confused how this happens. If I understand the DNF5 plugin correctly, it uses the ID variable from /etc/os-release that you showed us to be lowercase. And DNF4 plugin does some guessing magic, having several fallbacks. But in neither of them I can clearly see a problem.

Can you please let us know what DNF version are you using? So we can focus on debugging the right codebase.

dnf --version

In case, it is DNF4, these should hopefully help us locate the problem.

python3 -c "from distro import name, version, codename; print((name(), version(), codename()))"
python3 -c "from platform import linux_distribution; print(linux_distribution())"
cat /etc/os-release |grep -E "^NAME=|^VERSION_ID="

[jannau]

This is indeed an asahi specific issue. fedora-asahi-remix-release-common carries /usr/share/dnf/plugins/copr.vendor.conf with:

[main]
distribution = Fedora
releasever = 41

correcting the distribution to fedora fixes the issue. I'll see to get this fixed and this issue can be closed.

Great, thank you @jannau!
