I'm getting this:

$ make test
Running virtualenv with interpreter /usr/bin/python2.6
ERROR: None
ERROR: this script requires Python 2.7 or greater.
make: *** [Makefile:5: py26-test] Error 101

The only thing In the py26env is tox. Why can't system version be used?

I run it and it works (with proper packages installed before).

Updated to allow ignore python26 by setting an environment variable. This could be useful for rpkg for a while before python26 is installed back into slave.

Pretty please pagure-ci rebuild

After updating python2-virtualenv make test works on my machine. :thumbsup:

What is the right scenario (or correct command)?

[root@a3dfffed40a3 rpkg]# make test IGNORE_PY26=1
detox: invalid option -- 'e'
usage: detox [-hLnrvV] [-f configfile] [-s sequence] [--dry-run] [--inline] [--special]
      file [file ...]

otherwise (without IGNORE_PY26) it runs well and creates py26 virtual environment.

@onosek Based on my experience of make, command should be

IGNORE_PY26=1 make test

@cqi I am affraid output is completely same (I tried it previously).

@onosek Is it python2-detox-0.12-1.fc27.noarch?

actually detox-1.3.0-4.fc28.x86_64 was installed there. I replaced it with python2-detox-0.11-5.fc28.noarch and python3-detox-0.12-2.fc28.noarch respectively. Command make test IGNORE_PY26=1 is identical in my point of view. It works now - on docker container containing python3 packages it works completely. On docker container for testing python2 version of rpkg it works only when .tox directory and its content was already created.
But it is sufficient for me. Can be merged as per me. Thanks
