The NextCloud updater is really dangerous.
I have never upgraded it successfully, even once.
Well, this time, I ran the online updater from 12.0.5, and then it ran failed and I have to run a command to turn off the maintaining mode. When I can run the updater again, It showed me “Step 5 is currently in process. Please reload this page later.”.
I tried all way I can find by the search engine, nothing worked.
HELP! HELP! HELP!
