That seems to be a typical case of a CA-certificate out of date.
If you can look for the file "ca-bundle.crt" in your Boinc directory could you please tell us what its timestamp looks like?
Mine (still in Ubuntu 8.04 with Boinc 5.10.45) says "22 Feb 2008 21:40:08 CET".

Cheers. Jean.

I downloaded the file ca-bundle.crt. The computer will not allow me to move it to the directory where my boinc-manager is located. It is located in \usr\bin. For some reason it does not have its own folder.

Jean: Thanks for responding so quickly.

I was able to locate the file "ca-bundle.crt" on my system and it lives in the folder
"var/lib/boinc-client"

When I look at its properties the only dates it shows are the date-modified, which is Thursday when I upgraded Ubuntu, and the last time accessed, which is a couple of hours ago.

I tried downloading a new copy of "ca-bundle.crt" as per the instructions you linked to, but the system will not allow me to replace the file that is already in the folder.

I also found this location for the certificate " /etc/ssl/certs/ca-certificates.crt" which has an empty update folder and tried to move the downloaded copy of "ca-bundle.crt" there but again it was not allowed by the system.

Viewing the two "ca-bundle.crt" files with a text editor, they are not the same. The downloaded version has readable English text in it, and the version currently in the program appears to be large blocks of random letters and numbers with no spaces.

It is late here and I am going to call it a night, but possibly sign on as "root" tomorrow and see if I will be allowed to replace the "ca-bundle.crt" file with the freshly downloaded version.

Thanks again for your help, and any other suggestions you may have.

Best Regards,

I have version 6.2.12. I downloaded the version from wcg site and it is a shell program and it keeps telling me that I need to open it with wine. I have had enough problems with vista and boinc and now to have problems with ubuntu. I do not know if the problems are with the operating system or with the boinc program but someone should figure out these problems before wcg loses a lot of volunteers.

After spending several more hours trying to solve the problem of the completed worked units not uploading I am still getting the same error messages in Boinc Manager:

At the same time, I am getting this error message in the terminal window:

I have tried numerous ways to copy a new "ca-bundle.crt" certificate file to replace the one that is there, but even as "root" the system will not allow it.

I have used the Synaptic Package Manager and twice re-installed Boinc and it has not made a difference. I still have four completed work units that are ready for upload.

As with the experience of "Rick the Brick" noted in this thread, the non-upload problem started with the upgrade of the Linux OS to Ubuntu 8.10 on Thursday afternoon. Prior to that, the system worked fine, and I did nothing else that would have changed anything.

It is apparent that somehow Ubuntu has included an old "pre-release" version of Boinc
with its new OS version, and on its Synaptic Package Manager. I doubt that "Rick the Brick" and I are the only two Ubuntu crunchers now having this same problem. However, many of the other upgraders may not have noticed yet.

This is likely a wide problem that should be addressed by someone above the cruncher level at World Community Grid and someone else at BOINC working with Ubuntu people on finding a fix that can be sent as an automatic upgrade or patch. Otherwise, a significant number of Linux crunchers will be unable to send back results.

Thankfully, none of my work units are due until the end of the week, and so I have turned off BOINC and will await an upgrade fix from Ubuntu.
