Is sspks still under development and support?
I installed sspks with successfully with docker. by adding a new spks (plex in my example) i get 5-10 Permission denied errors.
seems the Package.php has no permissions to rename the package.
i got the package 777 permissions already and its owner is root like the container.
so whats wrong here?
here is my container log:

The project is alive, again 😉.
It seems your cache directory is invalid. Have you tried specifying a full path for it?

Same thing here:
This is related to apache PrivateTmp
