I would like to add my usr ron to the docker group, so I did the following:

ron@regDesktopHome:~$ sudo usermod -a -G docker ron
ron@regDesktopHome:~$ groups
ron

Why does it only show group ron as the user obviously also is a member of sudo(+others)...?

edit

$ grep ron /etc/group
sudo:x:27:ron
dip:x:30:ron
crontab:x:102:
netdev:x:111:ron
vboxusers:x:124:ron
ron:x:1001:
incron:x:138:
wireshark:x:148:ron
docker:x:153:ron

Now something doesn't look right here: The following is after I opened a from XTerm instance on my desktop:

ron@regDesktopHome:~$ groups
ron
ron@regDesktopHome:~$ su ron
Password: 
ron@regDesktopHome:~$ groups
ron sudo dip netdev vboxusers wireshark docker
ron@regDesktopHome:~$

why would I first need to "relogin" as my own user in order to become a member of the groups, that doesn't seem to make sense, does it?

OK - at least your groups are still good. Try logging off, then back on. – ajgringo619 Aug 30 '19 at 04:20
