Group membership reported by id vs. contents of /etc/group
Clash Royale CLAN TAG#URR8PPP
I have some issues with permission from various apps (such as accessing serial ports, despite being the dialout group, or contacting to Docker daemon, despite being in the docker group -- I think) and I need clarifications here.
When I run the id command, I get this:
uid=1000(eudoxos) gid=1000(eudoxos) groups=1000(eudoxos)
I understand that Debian/Ubuntu create separate primary group for each user (gid 1000).
When I look inside /etc/group, I see my username in a number of other groups (those are secondary groups, right?), such as adm, sudo, audio, plugdev, fuse, docker, dialout and so on). The id command should report those, as per GID, current, primary, supplementary, effective and real group IDs? but I don't see anything like that in the output. What am I missing? Is something misconfigured? (I did login anew after changing groups already)

Just tested in a 18.04 VM and no problems at all. Did configure something on your own? Are you somehow in a docker or snap environment?
