Alpine Nextcloud Hub - tmpfs

[DrSpaldo]

I've just started using the Alpine Nextcloud Hub script / LXC and have been having trouble installing some of the apps. In particular, memories. When trying to enable the app, I get the following error:

An error occurred during the request. Unable to proceed.

After having a bit of a Google search for the issue, some suggest that you need to have the temp folder executable; https://memories.gallery/troubleshooting/#occ-commands-fail

How would I enable exec in the tmpfs folder / edit the docker?
