Hi,I have a problem which is very strange for me, I try to intsall AApnel in ubuntu 20.04 and 18.04 twice after installation complete, All command in terminal which use URL with ssl ,return this error:
Unable to locally verify the issuer's authority.
I check this issue with wget ,curl ,youtube-dl. all of them have this error.
I think during installation something changed in certificate of server but I can't what is that
