Hey @sergiopr89 -- thanks for reporting! I can't reproduce this on my machine -- are you using any xontribs?

[sergiopr89]

Wow, headshot!
Yes, the problem is with the apt_tabcomplete and docker_tabcomplete, one warning for each xontrib, that's why the error is shown twice. Try this:
xontrib load apt_tabcomplete docker_tabcomplete
I have both in the HOME .xonshrc file.
I've executed "sudo pip3 install --upgrade xonsh-apt-tabcomplete xonsh-docker-tabcomplete" but looks like they're already updated.

[sergiopr89]

I'm closing the issue, those xontribs are from 3rd party.
