I get this error on a fresh install of gitlab. The message looks like:
fatal: unable to access 'https://gitlab-ci-
token:xxxxxxxxxxxxxxxxxxxx@gitlab.example.com/something.git/': Peer's
Certificate issuer is not recognized.ERROR: Job
failed: exit status 1
Any suggestions on how to fix it?
You need to configure /etc/gitlab/gitlab.rb.
Change this line
nginx['ssl_certificate'] = "/etc/gitlab/<your-local-path>/cert.pem"
to
nginx['ssl_certificate'] = "/etc/gitlab/<your-local-path>/fullchain.pem"
(Assuming, you already have nginx enabled and you have correctly issued certificates, e.g. from LetsEncrypt.)
then restart gitlab and you're done:
$ gitlab-ctl reconfigure
Why - cert.pem does not contain full certificate chain, thus ca chain cannot be verified. Replacing with fullchain.pem solves it.
