didn't find any errors there
So, I got a message on my phone saying server no longer supported so started to look into updating.
- Problem was that I had PHP7.3 so couldn’t update to NC 23.
- Updated PHP to 7.4 and installed NC23.
- Then updated PHP to 8.1 and updated from NC23 to NC24 to NC25. Can’t remember what I updated when but got to the place that I now have NC25.
- I was offered NC26 via the Admin - Overview. Hit upgrade and it started. It hang at the four extra files that I had to delete, the composer and package files. I got the updater to continue but it then hang at extracting files.
- I had run out of space on my turnkey-root partition. The NC25 didn’t start anymore, gave a internal server error. I added space and resized the partition. NC25 started normally again. But now I no longer have the Update button available. If I switch to beta I’m offered NC26 RC1, but if I switch back to stable I again get “latest version” info
