Tranquil IT Forum

Hello,

when I try to install Wapt using "wget ​​-O - https://wapt.tranquil.it/debian/tiswapt-pub.gpg | apt-key add -"

, I get this error.



However, I have no problem downloading the file from a computer configured with the same proxy.

Thank you in advance for your help.

Your proxy is performing a man-in-the-middle attack (MITM) using a wildcard certificate. You either need to integrate it into your Linux system or create an exception on your proxy server.
