I think I would try, at least initially, with capture_output=False (the default). You might find that sudo/pkexec is trying to get you to authenticate, and this is failing because the output is being redirected. Particularly capture_output captures both stdout and stderr. If that works, then a solution that captures stdout only and not stderr might work better. sshuttle does something similar to start its firewall process, and then it talks to the firewall process via stdin/stdout. But it sort of grown organically and begging to be refactored into something that could be easier to understand. https://github.com/sshuttle/sshuttle/blob/master/sshuttle/client.py#L209-L337 sshutle also uses subprocess.Popen, hopefully for you application where you only need stdout subprocess.run should be sufficient. -- Brian May @ Linux Penguins _______________________________________________ luv-main mailing list -- luv-main@luv.asn.au To unsubscribe send an email to luv-main-le...@luv.asn.au
