To manage the TLS certificates, +I wanted to use certbot again. Alas, the version that Debian shipped +in their repos didn't support the deploy hook feature I needed for that (iirc). + +So to migrate, I uninstalled the apt repository certbot package, created an venv and installed +certbot via pip (or maybe the other way around), deleted the cronjob and +created a systemd unit instead to renew the certificates, yadda yadda. + +Fast forward to a few days ago when I realized my XMPP client on the smartphone +wouldn't connect anymore. A few days later I had the time to investigate. + +Sure enough, `certbot certificates` showed (nearly) all my certificates as expired. +Huh? + +After digging around in the system to find out what I did at all +("Why is there no cron job? … +Why does journalctl say there was an exit code of 1 of the service?") +I opened the unit / service file to find this line: + +``` +ExecStart=false && /usr/local/bin/certbot -q renew --no-random-sleep-on-renew +``` + +… Uuuuhhhhhhh… +I can only imagine this `false` got inserted during the migration phase. And +I forgot to remove it. -- cgit v1.2.3
