the solution seems enable cacert provider at /etc/ca-certificates.conf and executing update-ca-certificates command like said BrodocK at his comment:
https://bugs.launchpad.net/ubuntu/+source/ca- certificates/+bug/153625/comments/5 The Boinc site ( http://boinc.berkeley.edu/trac/wiki/ErrorReference ) said: /* Scheduler request failed: problem with the SSL CA cert (path? access rights?) This is a known problem with some ported BOINC releases, especially certain Linux x64 ports. The reason for the error is that a file (ca- bundle.crt) was omitted from the release. If you see this error message in your message log, then you probably need to apply this fix. 1. Determine your BOINC data directory. Check the beginning of your message log. There will be a line near the beginning like this: 08/06/2007 13:18:00||Data directory: C:\Program Files\BOINC 2. Download the missing file. - make sure you name the file ca-bundle.crt. 3. Place the file in your BOINC data directory. 4. Restart BOINC. The way you do this will depend on your installation. Why does this problem only affect WCG, and not other BOINC projects?This is because WCG is (at the time of writing) the only BOINC project that requires a secure connection to the server. Other projects permit falling back to an insecure connection. */ The missing file ( I think) is a generated ( update-ca-certificates ) ca-certicate.crt build from many (all ?) providers enabled ( /etc/ca- certificates.conf ) REFERENCES: https://bugs.launchpad.net/ubuntu/+source/ca-certificates/+bug/153625 http://boinc.berkeley.edu/trac/wiki/ErrorReference https://bugs.launchpad.net/ubuntu/+source/esniper/+bug/164264 https://bugs.launchpad.net/ubuntu/+source/boinc/+bug/159135 -- boinc unable to connect to World Community Grid because of missing ca-bundle.crt file https://bugs.launchpad.net/bugs/159135 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
