So I just installed ubuntu on my computer at work and when I try to add a ppa I get the following message:
Cannot add PPA: '"Error reading https://launchpad.net/api/1.0/~libreoffice/+archive/ppa: (60, 'server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none')"'.
I have tried various things that I have found in other forums but haven't had any success. Some of the things I have tried:
setting the time
sudo apt-get install --reinstall ca-certificates
I have tried adding the following ppas:
sudo apt-add-repository ppa:libreoffice/ppa sudo add-apt-repository ppa:xorg-edgers/ppa
Any idea why I am getting the error and how to fix it?
