Very Slow Sudo

Maybe this?

Another option would be update to current and see if the issue persists.

No effect.

I already had 127.0.0.1 localhost I tried 127.0.0.1 systemname and it made no difference.

I am on a Ubuntu 18.04 system that is very slow when issuing any command via sudo. It can take 30 seconds for the command to complete. Any other command is completed instantaneously.

The system has very little CPU and memory usage with no resource issues over a very long period of time. If I do sudo su and switch to root, I am able to run commands simultenously. It is only an issue when running sudo

Is this a Desktop or Server?

Which terminal emulator are you using?

This is a desktop and I am using terminator.

I launched the default gnome-terminal and I got a password prompt immediately. I entered in my pw and the sudo command had same delay :(. On subsequent sudo commands with gnome-terminal, I am having the same time out issue.

Everything I'm seeing for this is related to the hostname either not being in /etc/hosts or that file simply being misconfigured.

Shouldn't it be 127.0.0.1 localhost and 127.0.1.1 systemname

I do have some shit in my host file, so I copied it and then made a new one with just one line 127.0.0.1 hostname still no joy

As far as I know, all 127.* is the same loopback address.

I'll would compare hostnamectl, /etc/hosts and /etc/hostname

DustinB3403

I can't find anything else besides the /etc/hosts being screwy. This guy wrote a blog post on it just last year.

black3dynamite

If you were running the sudo command from root, is still slow too?

DustinB3403

Maybe the sudoers file is messed up?

Check /etc/resolve.conf

Is the DNS server valid and can the machine access it and do hostname lookups?

Ya it's the whole /8

All have the same hostname configured.

DustinB3403

@IRJ Did you check the sudoers file in /etc/suoders

Shouldn't it be 127.0.0.1 localhost and 127.0.1.1 systemname

So when originally troubleshooting I removed localhost and changed it to systemname I needed both.

how long has systemname been a thing?

I changed my system name like 2 months ago and thats around the time I had this issue. So yes it appears to be 100% related.
