i’ve got this error:
Now i am not able to call
occ preview:pre-generate again, because it says:
Command is already running.
But it isn’t, because
ps ax|grep generate
does not return anything.
PS: Nextcloud 11.0.1 on Ubuntu 16.04.
Looks like it waits a fixed 30 minutes before letting you run it again. You can either wait it out (as you probably have by now) or, if you’re impatient (like me) and really sure it’s not running already,
SELECT * FROM 'oc_appconfig' WHERE 'configkey' LIKE 'lastActivity' and delete that timestamp.
