Hello,
I am on F31 and have always used sudo. This morning, after a while, I finally rebooted and
am on the 5.5.8-200.fc31.x86_64 kernel. However, I appear to have lost my sudo access.
I get: that my username "is not in the sudoers file. This incident will be
reported."
Not sure how this happened. How do I get back into sudoers? I am not even sure I, (in fact
I think that I do not), have a root account.
Any suggestions? This is strange.
Ranjan

It's unlikely that you were ever in the sudoers file unless you added it
yourself. Normally the user is in the wheel group to make them admin
and allowed to use sudo. What does the "id" command show for you?

Hi,
Thanks!

and allowed to use sudo. What does the "id" command show for you?
I did not manually add the user but I have had sudo privileges because I checked the box
with regard to administrator privileges while installing long long ago.
I had no idea that id was a command (thanks!) but here is what it says:
uid=1000(username) gid=1000(username) groups=1000(username),7(lp)
context=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
In the above, username replaces my actual user name.
Many thanks again for your help, and best wishes,
Ranjan

Somehow you got dropped from the wheel group. Did you uncheck your
administrator access in the user control panel? In any case, if you
don't have another admin user, you will need to use a live or rescue
boot to add yourself back in to the wheel group.
Btw, you do have a root account, but it probably doesn't have a
password. "sudo -i" will make you root.

No, I did not uncheck anything (because nothing every came up for me to uncheck). I can
get into the rescue. What do I do after that?
Btw, you do have a root account, but it probably doesn't have a
password. "sudo -i" will make you root.
I see, but it requires the wheel access that you were mentioning, I guess.
Thanks again,

Since I'm not sure which rescue setup you have, I'll give you the easier
method. At the grub menu edit the boot entry and add "init=/bin/bash"
to the end of the linux line. This will boot you right to a root bash
prompt. Then run the following two commands, replace "username" with
your real username:
/usr/sbin/usermod -a -G wheel username
/usr/sbin/reboot -f

Yes. You mentioned that you didn't have a root account and I was
clarifying that you do, it just can't be logged into directly.

Hi,
I did this.

However, I get a bunch of selinux context stuff (in a line), at the end of which it says
"res=failed". This laptop is one of those 4K resolution ones and so has very
small print on the console and so I could not take a picture that is clear enough.
/usr/sbin/reboot -f
and it does not add wheel access.
Is it possible that I may have accidentally deleted a package which has this?

Actually, I missed a line earlier. I get:

and then gives this selinux stuff under audit:

I see that one.
and then gives this selinux stuff under audit:
I don't see that. Where did you find that?
Anyway, what I missed is that / is still read-only at that point. So
before the other commands I gave you, run:
mount -o rw,remount /

Hi, your latest suggestion resulted in success at the terminal but I don't have
network manager anymore or sudo access. So I have also lost access to the network. What
should I try? Thanks again, Ranjan

You still don't have sudo access? What does the "id" command show now?
It sounds like something went wrong with your update, but you won't be
able to do anything until you have sudo access again.
8:16 p.m.
My apologies, but I still don't have sudo access and I have now lost network manager.
id says exactly the same thing as before except that there is no "7(lp)" before
the context field.
My apologies again for any inclarity but because I am not on the network I cannot cut and
paste and have to type on my phone to write this email. Thanks.

Did the usermod command not work? If you boot with the init=/bin/bash
option again, do:
mount -o rw,remount /
vi /etc/group
/usr/sbin/reboot -f
In vi, go down to the wheel line and add your username to the end if
it's not already there.
10:18 p.m.
Hi, thanks. The wheel line reads:
wheel:x:10:username
So I guess it is there. However, I neither have sudo access or network manager.
Also, when I say
reboot,
I get:
Failed to connect to bus: Connection refused
Does this shed any light. Thanks!

That wasn't the command I gave you. It was:
/usr/sbin/reboot -f
But since you mentioned selinux errors, while in the root shell, run:
mount -o rw,remount /
touch /.autorelabel
/usr/sbin/reboot -f
When it reboots, it will do a full relabel of the filesystem. See if
that helps at all.
11:34 p.m.
New subject: missing from sudoers file after update (solved)
Thanks, the selinux relabeling appears to have been it. Everything including
NetworkManager is back on track again!
Thank you very much for your patient efforts!!
Best wishes,
Ranjan
