Take the 2-minute tour ×  Possible Duplicate: How do I add a
user to the “sudo” group?  I've added myself back into the
admin's group I think, by following this.  But I still can't do
commands like:  sudo aptitude update  I get the message
oshirowanen is not in the sudoers file.  This incident will be
reported.  How do I add myself into the sudoers group now that I
am in the admin group?  share|improve this question Appears to

@tachyons You might be thinking of this question about a similar
but different error. There, a syntax error prevents running
sudo. Here, entries may actually be missing. So I think an
optimal answer here must also explain how to add the usual
entries to allow administrators to use sudo. I've attempted such
an answer. I do not recommend that this question be made a
duplicate of that one, because unlike with a "little" syntax
error, answers there don't clarify how to edit. –  Eliah Kagan
