I have Dietpi 6.16 on a Raspberry Pi Zero that’s running Sickrage and Transmission. Yes it’s a bit slow, but it does work 
However, I’d noticed that the update function of Sickrage never did anything. Clicking “check for updates” on the web interface would cause it to pause for a bit, and then display the menu again.
I recently realised it was because GIT tools weren’t installed, so I did this via the dietpi-software menus.
Clicking Sickrage web-interface “check for updates” now took much longer, and told me it couldn’t determine what version I was running, but I could download the latest, which I let it do. It then sat there spinning “waiting for sickrage to restart”. It never did. Eventually, I shutdown and rebooted the Pi.
Sickrage would no longer start.
I fiddled about for some time, then gave up and rolled back to a previous backup using dietpi-backup to restore it. This worked well (thank you!) and it’s all good again, although I’m now back to sickrage being unable to update itself.
To get to the point :
Should an installation of sickrage automatically install git tools as well?
Should I even be trying to update sickrage itself from it’s own menus, or should I let dietpi software do that when it’s deemed reliable?
Because I’ve rolled back I don’t think I’ve got any useful logs to submit, but I am curious as to the above questions.
Many thanks
