Got this error with Rosetta and LHC 11:01am UTC 30th May 2020. On all my (Windows 10) machines, while requesting work.
"Peer certificate cannot be authenticated with given CA certificates"
But Universe and Einstein and Milkyway are ok.

Any ideas what screwed up? My computer? Both Rosetta and LHC at once? Boinc in general?

Add NumberFields@Home to that list. I'm getting

I don't normally check their logs as closely as that - it's one of the projects which runs very smoothly - but somebody else reported a problem around 11:30 UTC today.

With three projects affected, I wonder if something in BOINC's ca-bundle.crt has expired?

I don't understand how these things work. But in the LHC forum I was asked to check that file, and the date in mine (and the latest according to them), is "Fri Jan 26 21:30:21 2018 GMT" (4th line of the certificate) - which is rather old isn't it?!

But how come Milkyway, Einstein, Universe are not failing? I just checked and Universe is using https (the other two aren't). This is weird. Surely Universe should also be affected?

Message 98894 - Posted: 30 May 2020, 14:28:22 UTC - in response to Message 98889.  

I got a bit of an impromptu introduction to the subject a couple of years ago. I've checked through all those "133 certificates in ca-bundle.crt", and - although a few of them have expired - none of them died anywhere near 11 am today.

I'll look at those '402 certificates in /etc/ssl/certs' on my Linux machine, and see if they help - otherwise I''ll refer this one upstairs.

I've left a message for the NFaH admin (Arizona - probably not minding the shop at this time on a Saturday morning): he was "thinking of switching from http to https when this Pentathlon is over" earlier this month, so may have something to add.

Apparently Mac and Linux are ok according to the Rosetta forum. Seems odd that one OS thinks something has expired when another does not.

I've looked through the Linux certificate directory. All sorts of things in there, including what looks like a duplicate of our ca-bundle.crt under another name. It didn't work either.

The NFaH log I posted was from Linux, so it isn't as simple as 'Linux & Mac good, Windows bad'.

I've posted some extras in your LHC thread. Since moderator Toby Broom is paying attention (I think he's pretty clued up), that might be the best place. But I'll certainly report upstream once we have a clear idea where the problem lies.

Hi Richard,

there is an expired certificate:

# openssl crl2pkcs7 -nocrl -certfile ca-bundle.crt | openssl pkcs7 -print_certs -text -noout | grep -i after | grep 2020
            Not After : May 30 10:48:38 2020 GMT
            Not After : Mar 25 11:03:10 2020 GMT

# openssl crl2pkcs7 -nocrl -certfile ca-bundle.crt | openssl pkcs7 -print_certs -text -noout | less
...
Certificate:
    Data:
        Version: 3 (0x2)
        Serial Number: 1 (0x1)
        Signature Algorithm: sha1WithRSAEncryption
        Issuer: C=SE, O=AddTrust AB, OU=AddTrust External TTP Network, CN=AddTrust External CA Root
        Validity
            Not Before: May 30 10:48:38 2000 GMT
            Not After : May 30 10:48:38 2020 GMT
        Subject: C=SE, O=AddTrust AB, OU=AddTrust External TTP Network, CN=AddTrust External CA Root
...


"AddTrust External CA Root" is an old Comodo cert, now Sectigo, which expired today.

For more information, see:
- https://support.sectigo.com/Com_KnowledgeDetailPage?Id=kA01N000000rgSZ
- https://crt.sh/?id=1720081

We just need to replace the old Intermediate cert with the new Root CA cert: https://crt.sh/?d=1720081

Could you please file a bug report on GitHub? Otherwise I'll try to do this later/tomorrow...

Best wishes,

walli

Many thanks - I see it (#6 of 133). I'll do a bit of playing around, then certainly pass it on.

BINGO!

I hacked that new certificate into the bundle, and did a complete work cycle at NumberFields - Upload, report, download. All successful.

It's actually easy to do - the certificate is a cryptographic string, but just stored in text format. The COMODO download comes with Linux format line-endings - use Notepad++ to flip those to Windows. Then use the text editor of your choice to splice it into the bundle file. De-activate the old bundle file in your BOINC program directory, replace it with the new one, and simply retry the failed uploads - no need for a restart.

I'll do the GitHub issue next - feel free to pass the news round the boards while I'm busy.

I made the updated file for anyone that "trusts" me.

I can also confirm it works

I didn't do any conversion of line endings, seemed to work here anyway. I just pasted in https://crt.sh/?d=1720081 using Notepad

The news is already spreading...

Linux isn't or shouldn't be affected by this issue in most cases because the client looks for system-wide shared certificates (e.g. "/etc/ssl/certs/ca-certificates.crt" on Debian based distributions). I don't know how this works on macOS or Android.

Thanks all. GitHub issue at https://github.com/BOINC/boinc/issues/3789. NumberFields admin had started checking just before I reached him, but understandably didn't find any problem. I'll start firing out some emails to key people.

My Linux Mint (based on Ubuntu 18.04) got caught, but should be fixable the same way. I'll report back. Maybe I haven't updated recently enough.

Seems like the windows version of BOINC should do something like that, so the same thing doesn't happen next time certs expire?

Not immediately working, here. I've tried editing the file, restarting BOINC, rebooting machine. Nada.

Running update-ca-certificates by itself did nothing ('no files changed'), but with -f things did happen. No change in BOINC, though.

Copied the newly-generated ca-certificates.crt, renamed the copy as ca-bundle.crt, and put it where the BOINC file was (in data directory). Nada again, though without restart so far this time.

Restarted BOINC, no upload - but I did get my CUDA driver back this time (it went awol, and downloaded backup OpenCL tasks instead). So now I'm doing a full update/reboot.

Thanks. I ran "sudo update-ca-certificates", and it shows that the "ca-certificates.crt" file (in /etc/ssl/certs) now has today's date.
But whether anything is changed in the file is not clear.
I will know at midnight UTC, or so it appears.

I copied the downloade 1720081.crt to /usr/local/share/ca-certificates and did a sudo update-ca-certificates and it worked.
