@Vogtinator @M0ses unfortunately this fix is not compatible with CentOS 7 (python 3.6):

Any idea if there's a way to make it work there too?

[Vogtinator]

read_string was introduced in Python 3.2. Does it use python 2 by chance?

[bluca]

Hard to tell from that log - both python2 and python3 are installed, that much can be seen, so maybe it is?

[Vogtinator]

-bash-4.2$ head /usr/lib/obs/service/tar
#!/usr/bin/python

urgh

[Vogtinator]

@adrianschroeter @dirkmueller @M0ses Is there a reason why on those platforms it uses python 2 still and we can't switch over?

That CI support for py2 was removed makes dealing with this a bit annoying.

The easiest option here is probably to keep the old code around in case if "read_string" not in dir(config)...

Is there a reason why on those platforms it uses python 2 still and we can't switch over?

e.g. CentOS7 is missing python3-dateutil
