Hello everyone,
I had this problem this morning and it is the corruption of the file /
etc / group that no longer contained the list of user privileges. If the
file is correct, another investigation found that at the end of comment.
Here is the file before the correction:
root:x:0:
daemon:x:1:
bin:x:2:
sys:x:3:
lp:x:7:
mail:x:8:
news:x:9:

www-data:x:33:

pulse:x:117:
gdm:x:119:
