SyntaxError raised by lib/galaxy/metadata/__init__.py

Hi,

I see that we have a syntax error coming from lib/galaxy/metadata/__init__.py

more galaxy_3611.e
Traceback (most recent call last):

This is python Python 3.8.13 and Galaxy 22.01 installed from ansible.

Thank you

Fred

I think I've missed something around python? It seems that a python 2 is being used no?

Hmm, yes, it looks like the python used for running the metadata script was an unsupported python version.

[FredericBGA]

for the records: This was due to a problem of rights. Everything was working nice on the Galaxy's VM. But when using a computation node, the path to the galaxy's .venv was denied. So python command was the one in /bin, a python2 version of course.

If you are here, for us it was that the ansible install was made pointing to a python binary that was available on the main galaxy machine, but not on the execution nodes of the cluster, so the venv was being correctly activated, but python was not there in the venv for the exec nodes.
