Many thanks for youre report. From which DietPi version did you upgrade? With v6.24 => v6.25 we did a Gitea reinstall indeed, but v6.25 => v6.26 did not touch it.
Which SBC/device do you use?
Please try to simply reinstall it: dietpi-software reinstall 165
Working version was a clean install of v6.25. That device got re-purposed and I had to stand up a new RPi3 and failure occurred when clean installing v6.26 (which now doesn’t make sense given you didn’t change anything).
Have just tried dietpi-software reinstall 165 and it is still not starting (same status error). The pi is not doing anything at the moment so more than happy to try any suggestions/clean install etc. if anyone has other suggestions
