Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)

[manjotsc]

I added a user "dcauth" to group "root" but can't run apt update

Thanks.

You need to be a part of the sudo group.
Then run as root with sudo.

Currently you're trying to run root commands as a non-root member.
Being part of root group doesn't matter.
