I installed Rocket.Chat in spring 2022 using the official package on the DigitalOcean marketplace. It used snap, which I am told is not the preferred method for setting up a Rocket.Chat server.
I’ve encountered difficulties that have on occasion left my server in an unusable state. I’ve created a checklist for updating that has helped to mitigate problems, and I thought I’d share it here for the benefit of any who may have encountered similar issues:
First, enable backups. If anything goes wrong, you can simply revert the VM to its prior state. In my case, I have weekly backups enabled with DigitalOcean. I perform Rocket.Chat updates shortly after such backups have been made, to minimize the risk of data loss. Then:
remove local backup:
rm -r /opt/Rocket.Chat.bkup/Rocket.Chat
upgrade rocketchatctl:
rocketchatctl upgrade-rocketchatctl
upgrade rocketchat:
rocketchatctl update
POSSIBLY NECESSARY TROUBLESHOOTING STEP
edit rocketchat.service file
nano /lib/systemd/system/rocketchat.service
Delete or comment out:
Environment=OVERWRITE_SETTINGS
reload daemons:
systemctl daemon-reload
Re-set site URL if needed
In case of problems, to obtain service logs:
journalctl -u rocketchat -e
