sudo password don't work

I have had this problem more times. Sometimes, randomly, the sudo password doesn't work, but i don't know why. What I do to solve for a moment it's restart the PC. I don't know why this happens. If anyone could help me I would appreciate it. Thanks

Re: sudo password don't work

maybe faillock - several failed attempts cause using password to be blocked (I think failing also include sudo timeout)

Re: sudo password don't work

Log in as root and try to reinstall pambase and see if the issue persists.

pacman -S pambase

Re: sudo password don't work

Keyboard layout?  Shift lock?  What happens if you change consoles and log into a terminal?

The layout is spanish and when I failed the password twice I always type very slow and looking if a type the wrong key.

What happens if you change consoles and log into a terminal?

I switch to tty and there I can log in my user but not in root

Now that is interesting.   I only use a US layout;  does anyone who uses different layouts know if one needs to change the layout for root?

Re: sudo password don't work

The console keyboard layout is set in /etc/vconsole.conf and applies to all users, including root.

Re: sudo password don't work

sudo passwd -S root

the sudo password doesn't work, but i don't know why.

Neither do we.
What's the actual error message?
Do you authenticate as your regular user or root?

maybe faillock - several failed attempts cause using password to be blocked (I think failing also include sudo timeout)

I have restarted this, IIhope it doesn't give me more errors

So faillock was in place and resetting it fixed the problem?

Something triggers faillock - either you, fat-fingering passwords, or some script/cron-job that runs sudo and times out on the password because there's no interface and nothing provides it.
sudo gets audited, so check your system journal itr.
