On Ubuntu 20:

# apt-get install samba

Good information: http://linux-training.be/networking/ch21.html

Let more or less as it is for a simple file sharing.

• Samba needs “own” users
• But the user must exist in linux before creating the corresponding samba-user.
• By removing is the same way but in the other direction: first remove the samba-user and then the unix-user
• The passwords for unix and samba can be different but setting the same make the life easier (!)
• Even if setting into etc/samba/smb.conf, the sync of the users between unix and samba seems not to work ⇒ disable the sync into /etc/samba/smb.conf and sync by hand with the CLI
