I wanted to update (=git pull) an older copy of ffmpeg's source to its most recent state. This setup always worked, but now I got the following error message:
fatal: unable to access 'https://git.ffmpeg.org/ffmpeg.git/': server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
[SOLUTION]
The CA-certificates were outdated and needed to be updated.
So simply update the "ca-certificates" package (eg on Ubuntu/Debian based distros).
You can use a GUI, but here's the simple commandline version:
Code: Select all
$ apt update && apt install ca-certificates
