Thanks, but I prefer not, packages avoid breaking a good system.
Anyways the issue seems to be with the rpm package.
My Guess is the problem is I the spec file.


rpm package no issue.

I guess the above bash script is just updating the crystal repo file, then install it.

[root@zw963 yum.repos.d]# yum install crystal

Nothing to do.

From which repository are you installing this package? Fedora 37 is not yet available in the official packages hosted on (OBS does not support it yet).

Thanks for the update.

if I modify the /etc/crystal.rep as

name=Crystal (Fedora_37)

Then it does install the proper version (FC37), but the problem is stil there.
My guess is it was tested for Suse, and something wrong in the RPM , still.

Sorry, I have very limited experience with RPM packaging systems. So any assistance is welcome.

The packages are generated for every repository from this spec file: File crystal.spec of Package crystal - openSUSE Build Service

There is a Conflicts: crystal line which is a likely cause for this.

IIRC, the idea was to express that this package conflicts with other packages that provide crystal as well (say crystal1.4 for example). But apparently, it doesn’t work like this? Well it works at least partially because the conflict does not prevent you from installing the package itself but it pevents from installing other packages such as crystal1.4.
