Pidgin 에러 : The certificate for omega.contacts.msn.com could not be validated.
It looks like the MSN certificate got expired for pidgin.
Please remove the file omega.contacts.msn.com. present under /root/.purple/certificates/x509/tls_peers/ or /home/username/.purple/certificates/x509/tls_peers/
Download the same from http://files.andreineculau.com/projects/pidgin/omega.contacts.msn.com.txt. Once it has been downloaded, move it as omega.contacts.msn.com from omega.contacts.msn.com.txt.
Restart Pidgin, it should work properly.
mv omega.contacts.msn.com.txt omega.contacts.msn.com
Restart Pidgin and you should be good to go
