I saw that JMSolo might publish a new update to QB today, since radarr/sonarr/jackett now supports/requires Mono v5.10 - If you’re lucky, there has been some attention to the updater scripts as well… Otherwise I would just update it manually and be done with it.
What I did was rather simple.
Get the latest version here: https://github.com/tidusjar/Ombi/releases
Normally on QB linux.tar.gz
Make sure to unblock the archive file if you’re on windows (Something I always do, so not sure if it’s necessary here).
Stop Ombi service on QB dashboard
Make a backup of /opt/Ombi to for instance /home/username/Ombi_backup
Overwrite files from the zip archive on /opt/Ombi
Start the service on the dashboard
Should be everything - And the updater script should start to work again =)
Let me know if it works out =)
