Description Jan Stourac 2021-11-25 16:26:32 UTC

Description of a problem:

Cannot install both `python-podman-api` package together with `python3-podman` package due to the files conflicts.

Platform RHEL8.5, tested architecture x86_64, but may be present on others too.


Version-Release number of selected component (if applicable):

python-podman-api version is: 1.2.0-0.2.gitd0a45fe.module+el8.3.1+9857+68fb1526
python3-podman version is: 3.2.0-2.module+el8.5.0+12582+56d94c81


How reproducible:

always


Steps to Reproduce:
1. install a brand new RHEL8.5
2. subscribe against RHEL appstream repositories 
3. sudo dnf install -y python-podman-api python3-podman


Actual results:

Error: Transaction test error:

Expected results:

package installation succeeds OR metadata in packages are set so that these packages have `conflicts` or `obsoletes` metadata set properly

Additional info:

Truth is that I can see in pulp repo that there are two newer releases of python-podman-api but for some reason I don't see these on my machine?

python-podman-api-1.2.0-0.2.gitd0a45fe.module+el8.4.0+10193+e90fd8eb.noarch.rpm	2021-04-05 16:46	43K	RPM package file
python-podman-api-1.2.0-0.2.gitd0a45fe.module+el8.5.0+10223+f7559c42.noarch.rpm	2021-09-29 10:00	43K	RPM package file

Not sure whether this is related to this issue somehow https://bugzilla.redhat.com/show_bug.cgi?id=2015824.


Also, I'm not completely sure that my expectations are 100% correct. Maybe I'm missing some important bit here. But I would expect that conflicting packages shall have this info in their metadata. Truth is that result of the operation is same but it feels a bit more correct way :)

I don't know why/how the package was installed. Will monitor if uninstalling it causes any problems.

Comment 4 Coty Sutherland 2022-08-23 12:38:30 UTC

I ran into this same issue when attempting to dnf update on Fedora 36; I don't see a Fedora bug anywhere so dropping a note here in case it's helpful... For me, the python3-podman-api package wasn't even installed, the update was attempting to install it and causing a conflict within itself. To workaround it, I just excluded the package from the upgrade: `dnf update -y --exclude=python3-podman-api`

Comment 5 Blaise Pabon 2022-09-08 12:40:51 UTC

Thank you @csutherl , 

I'm also running Fedora36 server and I ran into this issue and the earlier suggestion of `sudo yum remove python3-podman-api` did not work.

> dnf update -y --exclude=python3-podman-api

did the trick!
