Circled back to this. Updated my Ubuntu container. Purged Local and installed 1.6.2 from the .deb and the app is launching again! and I can create a site!
Router mode is working ok! Still no luck with site domains… I tried installing and running lxpolkit but it shows “No session for pid 23661” and doesn’t load.
Manually editing the /etc/hosts file doesn’t do the trick as Local still thinks the host entry is missing (or I’ve done it wrong)
