I deleted the web interfrace folder somehow

[bakissation]

Hello,

So CUPS is working completely fine, but I lost the WI and the web folder completely (idk how, but I belive I did it, I trust my ability to do such mistakes) , I don't want to reset my system, any suggestion on how to restore the GUI it was really useful?

I'm guessing the CUPS Web Interface isn't in a disabled state, so enabling it with sudo cupsctl WebInterface=yes won't have any effect, because if you go to http://localhost:631 and it were disabled, it will tell you to enable the web interface using that cupsctl command

Assuming you did delete the actual CUPS web folder which has the static content, it is typically either /usr/share/cups/www/ or /usr/share/doc/doc-root/ (or whatever the equivalent is for your Linux distro). Most Linux distros allow you to re-install packages without replacing config files.

Without knowing your Linux distro, it is hard to give advice.

On Fedora and RHEL you can do the following to reinstall the cups package which has the /usr/share/cups/www/ static web content:

sudo dnf reinstall cups

On Debian or Ubuntu, I believe it would be the cups-server-common package that has /usr/share/doc/doc-root static web content:

sudo apt  install --reinstall cups-server-common
