openSUSE Tumbleweed - Python 3.10 - No package metadata was found for vorta

2022-07-17T00:00:00+02:00

I'm using Vorta, a Desktop Client for BorgBackup, on my Notebook with openSUSE Tumbleweed, which stopped working after upgrading Tumbleweed to a Version that started using Python 3.10 as default.

Error message when starting vorta from the command line:

vorta

Traceback (most recent call last):
  File "/usr/bin/vorta", line 33, in <module>
    sys.exit(load_entry_point('vorta==0.8.2', 'gui_scripts', 'vorta')())
  File "/usr/bin/vorta", line 22, in importlib_load_entry_point
    for entry_point in distribution(dist_name).entry_points
  File "/usr/lib64/python3.10/importlib/metadata/__init__.py", line 957, in distribution
    return Distribution.from_name(distribution_name)
  File "/usr/lib64/python3.10/importlib/metadata/__init__.py", line 548, in from_name
    raise PackageNotFoundError(name)
importlib.metadata.PackageNotFoundError: No package metadata was found for vorta

I use the openSUSE Tumbleweed build from https://copr.fedorainfracloud.org/coprs/luminoso/vorta/, first tried to update it, but that dropped a dependency error:

sudo zypper up vorta

Loading repository data...
Reading installed packages...
Resolving package dependencies...

Problem: nothing provides 'python3-secretstorage' needed by the to be installed vorta-0.8.7-2.suse.tw.x86_64
 Solution 1: do not install vorta-0.8.7-2.suse.tw.x86_64
 Solution 2: break vorta-0.8.7-2.suse.tw.x86_64 by ignoring some of its dependencies

Well, sure that there is no secretstorage package for python installed? Let's see:

sudo zypper se secretstorage

S | Name                    | Summary                                              | Type
--+-------------------------+------------------------------------------------------+--------
i | python38-SecretStorage  | Python bindings to FreeDesktoporg Secret Service API | package
  | python39-SecretStorage  | Python bindings to FreeDesktoporg Secret Service API | package
i | python310-SecretStorage | Python bindings to FreeDesktoporg Secret Service API | package

Looks good but the vorta package expects "python3-secretstorage" and not "python310-SecretStorage", let's ignore the zypper warning about missing dependencies and just install the latest version of vorta:

sudo zypper up vorta

Great, started vorta again from the CLI, but now "PyQt5" is missing:

There is no rpm package so I installed it globally via pip:

sudo pip3 install PyQt5

Afterwards vorta could be started without issues, immediatly created a backup and uploaded the files to BorgBase

Overall not a big deal, the fact that the vorta rpm is expecting a dependency that can't be found on openSUSE Tumbleweed, even though it's installed but with a different name, is more of a cosmetic issue in my opinion, writing this blog post took probably longer than fixing the actual problem ;)
