We have a Landscape server to keep our Ubuntu PC's wellbehaved. When they boot for the first time, they are supposed to apply for a Landscape membership with:
landscape-config --import=https://landscapehost.rug.nl/config/bootstrap.conf -t $(hostname -f) --script-users=me,you,everybody --silent --registration-password=verysecretofcourse
But this fails with:
Fetching configuration from https://landscapehost.rug.nl/config/bootstrap.conf...
Couldn't download configuration from https://landscapehost.rug.nl/config/bootstrap.conf: Error 60: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none
Now, when we fetch the bootstrap.conf with a browser, it doesn't complain.
Wget complains about the certificate on some machines, but not on all, most notably not on the client we are trying to connect to Landscape.
But ssl reports a self-signed certificate in the chain:
openssl s_client -host landscapehost.rug.nl -port 443
CONNECTED(00000003)
depth=3 /C=SE/O=AddTrust AB/OU=AddTrust External TTP Network/CN=AddTrust External CA Root
verify error:num=19:self signed certificate in certificate chain

The issuer of this certificate is the same as the signee. We'd expect that only at the top of the chain. |
