  #Do not worry if the below command says no file or directory
  sudo rm /etc/apt/preferences.d/nosnap.pref 
  sudo apt-get update
  sudo apt-get install snapd
  #For Raspberry Pi Users alone:
        sudo nano /etc/ld.so.preload
        Comment the line that says /usr/lib/arm-linux-gnueabihf/libarmmem.so
  sudo snap install snap-store

2. Install nextcloud:   
   sudo snap install core

   sudo nextcloud.manual-install ADD_YOUR_USERNAME_HERE ADD_YOUR_PASSWORD_HERE
   sudo ufw allow 80,443/tcp

3. If you want to change the data to a external drive follow the instructions below, else skip:
   a. Format the external drive as ext4. Do not cut corners, NTFS or FAT32 will not work.
   b. Insert the drive and get the name of the drive.
   c. Change permissions of the drive
      sudo chown -R 0770 PATH_TO_YOUR_DRIVE
   c. Now we need to change the config
      #Stop nextcloud
      sudo snap stop nextcloud
      #Change the config
      sudo nano /var/snap/nextcloud/current/nextcloud/config/config.php
      #Scroll over to 'datadirectory' and change the path against that value and save.
   d. #Move  existing data to the external drive
      sudo mv /var/snap/nextcloud/common/nextcloud/data PATH_TO_YOUR_EXTERNAL_DRIVE
   e. Restart nextcloud
      sudo snap start nextcloud
   
4. Setting HTTPS access:
   a. Stop nextcloud
      sudo snap stop nextcloud
   b. Generating self signed certificates
      sudo nextcloud.enable-https self-signed

5. Adding trusted domain:
   a. Get your ip address of the board/computer
      #Note the IP Address from the below command
      ifconfig
   b. sudo snap disable nextcloud
   c. sudo snap enable nextcloud
   d. sudo nextcloud.occ config:system:set trusted_domains 1 --value=PLACE_THAT_PREVIOUSLY_NOTED_IPADDRESS_HERE
