This is a duplicate of issue #114 - it was resolved in the latest release 2.0.3, please upgrade.

I don't manage the Ubuntu repo (in fact this is the first time I hear of it having been released there) so please contact the maintainer to let them know as well.

[gariemiller]

Thanks for the quick response Rob. Sorry I didn't notice the earlier 114. I am considering filing a Bug Report at Debian or Ubuntu but they will pick 203 up in their repo at some time in any case.

I see 203 is in Debian "Sid". It will probably get picked up when they release "Bullseye" next year, and thence to Ubuntu 22. I think a Bug Report in this case would clutter things.

Hi Garie, thanks for following up. I guess things (understandably) move quite slowly at Debian/Ubuntu, might be best to just use PyPI which I keep up to date. pip3 install pcbasic should work just fine...
