Pitkästä aikaa tuli ongelmia Ubuntun kanssa.
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
curl: (77) error setting certificate verify locations:
CAfile: /etc/ssl/certs/ca-certificates.crt
CApath: /etc/ssl/certs
gpg: no valid OpenPGP data found.
E: The repository 'https://download.mono-project.com/repo/ubuntu stable-bionic Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
Toki yhdellä rivellä /etc/apt/apt.conf tiedostossa nuo ongelmat voi poistaa ja samalla certin tarkastuksen, mutta olisiko vinkkejä miten homma korjataan?
