@scuttlebutt I self host with my little compose file that I share here: https://github.com/dolanor/dsuite Nextcloud for files, calendar, contacts, that I mostly use on my phone thanks to iCal/iContact synchronization. I stopped automated upload of picture as it seems (or used to at least) that it duplicates each picture for uploading. And it was not that reliable either, so I just do upload my picture manually in another way (rsync on the folder that is synchronized via the desktop nextcloud client). It's for my family and some few close friends, so less than 10 people at the moment. I centralize the account with a LDAP that I learned for the occasion. Next step would be to add SSO and real integration with a picture gallery, because I'm not totally convinced by the nextcloud one. (It's old, though, I should update it, but life decided to make me very busy for a while) But even with all the quirks (that are not so numerous), I can't recommend nextcloud enough.
