Describe your issue
I’m trying to update Piped from version 2025.06.15~ynh1 to 2025.06.22~ynh1, but the package update script fails while attempting to clear old Gradle files.
Similar to this thread, except running sudo yunohost tools basic-space-cleanup and deleting old backups to make more storage space, didn’t help.

WARNING - rm: cannot remove '/var/www/piped/.gradle/caches/modules-2': Directory not empty
ERROR - Could not upgrade piped: An error occurred inside the app upgrade script
Full log here:

Try this :
sudo apt autoclean -y && sudo apt autoremove -y
sync; echo 3 > /proc/sys/vm/drop_caches && swapoff -a && swapon -a
sudo yunohost tools basic-space-cleanup
And reboot system ?
Then,
yunohost app upgrade piped
Otherwise
upgrade an existing install:
sudo yunohost app upgrade piped -u https://github.com/YunoHost-Apps/piped_ynh/tree/testing

same output here when i quick checked the previous log, but not the same context, i’m not low on storage.
here’s my log

this log is mouthful for just this at the very end:
2025-06-25 14:07:55,314: WARNING - rm: cannot remove '/var/www/piped/.gradle/caches/modules-2': Directory not empty
2025-06-25 14:07:55,920: ERROR - Could not upgrade piped: An error occurred inside the app upgrade script
Have you made a backup of Piped before update?
Personally, I will try to delete manually with the sudo command if you are not in root:
`sudo rm -rfv /var/www/piped/.gradle/caches/modules -2 ’
If during the update the script cannot delete `/var/www/piped/.gradle/caches/modules-2 ', why not do it manually?
« I specify that personally, I will use this method »
I do not think this is a risk since in the event of concern, you can do a restoration with the backup.
And update then:
Yunohost app upgrade Piped

Manually deleting the folder helped. Now I get a new error 
userdel: user piped is currently used by process 131046
deluser: `/usr/sbin/userdel piped' returned error code 8. Exiting.

Manually deleting the piped user and stopping the Piped services before retrying the update, eventually brings me back around to the original error…
sudo rm -rf /var/www/piped/.gradle/
sudo yunohost service stop piped-api piped-proxy
sudo userdel piped
sudo yunohost app upgrade piped

…Oh, lol, your first suggestion seems to have been the solution.
I don’t know why it would have made any difference – apt cleanup and yunohost tools basic-space-cleanup didn’t actually remove much, and I’d tried rebooting before already. But the update finally worked this time.
Thanks!
