Failed to get version when building charm with version 3.0.7

Using charm-tools 3.0.7 (+git-0-b7128ec)

Getting the following error building the ovn-central charm:

The above was from charmcraft, if i run it manually it fails at the same point:

$ charm build

hmm a second attempt of the build did succeed. The version that charmcraft is using is one commit behind HEAD:

$ git cherry -v b7128ec

• 25e5ef0 Upgrade setuptools

But that does not seem related to the issue.

The latest version of the charm snap in 3.x/stable does not contain the above patch and I think that is the reason why charmcraft buildis failing in CI but not when run the build locally. When I run it locally I get setuptools 59.6.0-1.2ubuntu0.22.04.1 but in the CI it needs that upgrade step to get the same version hence why it is failing. So we need to get a new build of this snap that include that patch so that charmcraft can consume it.

tested with the latest version that includes that patch and it still fails
