justinquinn I've tried your steps but didn't have luck. I'm not working with a VM so creating a new account isn't an option, unfortunately. I created a new account on this computer but I still get the same error.
Basically, when I run wget I get the following error:
ERROR: cannot verify URL's certificate, issued by ‘CN=Let's Encrypt Authority X3,O=Let's Encrypt,C=US’:
Unable to locally verify the issuer's authority.
I was doing some research and it seems that I removed some SSL certificates ('ca-certificate') somehow while uninstalling the first OpenSSL I'd installed before.
$ dpkg -l curl wget ca-certificates openssl

ii wget 1.17.1-1ubuntu1.5 amd64 retrieves files from the web
This is the reason why I can't access any URL and be able to download their files (I think). I was trying to find a way to install these certificates again (I think I need one called Let's Encrypt Authority X3) but I'm a little bit lost.
I was looking at these websites in order to solve this issue:
I don't know if you can help me with this. Nonetheless, thanks a lot for your patience and time throughout these days.
