# Add yourself and www-data to a shared group

### Create a shared group:

sudo groupadd ncshare

### Add both users:

sudo usermod -aG ncshare zaine
sudo usermod -aG ncshare www-data

### Set the folder to that group:

sudo chown -R zaine:ncshare /home/zaine/master-folder
sudo chmod -R 775 /home/zaine/master-folder

<2026-03-25 Wed> fixes:

Up To Date Fixes: We need to add zaine to the www-data group:

  sudo usermod -aG www-data zaine

Then we need to make the directories setgid, so that any new files created will have the group www-data:

  sudo chown -R zaine:www-data /home/zaine/master-folder
  sudo chmod -R 2775 /home/zaine/master-folder # the 2 sets the setgid bit, which means that new files will inherit the group of the directory, which is www-data

Older fixes

So apparently, nextcloud needs to have www-data as the owner of the files, and to do that, we need to run the following command:

sudo chown -R www-data:www-data /home/zaine/master-folder

I modified the build scripts to change permissions back to zaine:zaine when deleting the output folder, then changing it back to www-data:www-data.

One other useful thing may be:

  docker exec -u 1000:1000 -it nextcloud-app-1 php occ files:scan --all

  # or

  docker exec -u 1000 nextcloud-app-1 php occ files:scan --path="zaine/files/master-folder"

One other thing:

    i FIXED IT BY doing this:

  there is some issue in the nextcloud permissions itself. if i create a file and delete it in windows, i get this error in the client: A
  master-folder/hehe.txt
  now
  The resource you are trying to access is currently locked and cannot be modified. Please try changing it later, or contact your server administrator ...

  and if i try to delete it in nextcloud ui (web), it says file cant be deleted

Config

sudo nano /var/lib/docker/volumes/nextcloud_nextcloud/_data/config/config.php

Legacy stuff

Something I've been trying to reverse proxy ahead of time. Go to https://zserver.zapto.org/nextcloud , you'll be prompted to login with a username and password: Here's your credentials:

Username: halima Password: loser2104!

Once you've logged in, I've set up your account already, so there should be a calendar already there.

To get your phone logged in, there's two ways:

go to the following address: https://zserver.zapto.org/nextcloud/settings/user/security , scroll to the bottom, under devices and sessions, type in a random name (iphone), and click create new app password. You should then be able to generate a QR code (next to or under the password field), then you can scan that on your iphone app.
inside the app, type the following URL: https://zserver.zapto.org/nextcloud then follow the instructions.

Im thinking of having this as our shared calendar and file system. The only users are us 2 and its completely off the internet (self-hosted).

network issues resolved by:
