I checked out your edit and what’s going on is pretty weird. my recommendation (if you don’t wanna just use the native import/export feature and give up on DB dumps) is to (on the new server) create a minimal tandoor docker-compose.yml, run it, do minimal setup, see if it works, and if the fresh container works, check the permissions, then just replicate those perms for your other postgres directory that contains data you actually care about. good luck!

you’re probably right about it being a permissions error but also including some relevant logs would be useful (or just stick all of them on pastebin or something and give us a link). could also be a docker misconfiguration considering it’s a different system and I assume they’re not identically set up with Ansible or something similar

edit: also id personally use tar because I’m not entirely sure zip files preserve linux permissions

edit again: from 2 seconds of google searches, I think I’m correct about that, so definitely try using tar

not sure where you are but in the US I see a lot of cheap used laptops being sold online with broken screens for example or messed up keyboard/touchpad, etc. stuff that would make it awful for use as a laptop but almost entirely unimportant for a server use-case (if the kb/touchpad is dead you can just plug in an external during initial setup/troubleshooting). of course you gotta make sure that it wasn’t damaged in a way that would matter more. ex: if the kb/touchpad are broken due to water damage I’d be wary of issues with other vital parts
