Hi, is this instance running with 64bit PHP? Can you show a screenshot of the serverinfo app?

[Hiyoal]

I managed to find a fix due to the deprecation with php 8+.

I don't know how to use Github properly so I'll post my fix here. Hopefully someone who's more skilled than me can pull this.

File in question: https://github.com/nextcloud/server/blob/master/apps/files/lib/Command/ScanAppData.php

Line 242: Currently - return sprintf('%02d:%02d:%02d', ($secs / 3600), ($secs / 60 % 60), $secs % 60);

Changed to- return sprintf('%02d:%02d:%02d', intdiv($secs, 3600), intdiv($secs, 60) % 60, $secs % 60);

occ files:scan-app-data works after this change is made.

@Hiyoal mind to make a PR to review? Thanks.

I also have this problem in v25.0.1 not every time i run the scan but often.

@st3iny We can close this now, right?

Not yet. The command scan-app-data is still affected by the deprecation. Only scan was fixed.

Hi, please update to 24.0.9 or better 25.0.3 and report back if it fixes the issue. Thank you!

My goal is to add a label like e.g. 25-feedback to this ticket of an up-to-date major Nextcloud version where the bug could be reproduced. However this is not going to work without your help. So thanks for all your effort!

If you don't manage to reproduce the issue in time and the issue gets closed but you can reproduce the issue afterwards, feel free to create a new bug report with up-to-date information by following this link: https://github.com/nextcloud/server/issues/new?assignees=&labels=bug%2C0.+Needs+triage&template=BUG_REPORT.yml&title=%5BBug%5D%3A+
