I have installed some certificates and after I did it i have a lot of problems with the ppa and git:
sudo apt updatereturns errors for missing release files where they actually are:
server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none E: The repository 'https://deb.opera.com/opera-stable/dists/stable stable Release' does not have a Release file. N: Updating from such a repository can't be done securely, and is therefore disabled by default.
But if you follow the link above you will see that there is a Release file.
adding a repository via terminal results in this message, no matter what user/ppa I try to add:
Cannot add PPA: 'ppa:~teejee2008/ubuntu/ppa'. ERROR: '~teejee2008' user or team does not exist.
git pull origin master
fatal: unable to access 'https://path-to-repository.git/': server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
A workaround here is to set
export GIT_SSL_NO_VERIFY=1, but it is not a nice solution.
Because the certificates I have already installed are not necessary anymore, is it possible to revert the certificate system to default without reinstalling the elementary OS?
