You need Git for Windows. Do you have it installed?

Have also posted in getting started session.

BOINC 7.19.0
Ubuntu 22.04
Git 2.34.1

Don't know what other information you might need System is AuthenticAMD
AMD Ryzen 7 3700X 8-Core Processor [Family 23 Model 113 Stepping 0]
(16 processors) with 32GB RAM

Perhaps I am not understanding, the instructions here do I need to carry out those steps whatever or only if participating directly and not through BOINC? possibly relevant to OP?

Edit: trying to carry out instructions I get
curl -fsSLo loda https://github.com/loda-lang/loda-cpp/releases/latest/download/$LODA_EXEC
curl: (22) The requested URL returned error: 404

You don't need to manually install LODA. All you need is git.

Can you please check if /tmp is writable?

Owner root.
others Read&write.

Edit: I think of myself as a reasonably competent Linux user. I compiled BOINC from source and am one of the testing crew/moderators over at CPDN but know I still have a lot to learn about some aspects of BOINC. But do feel free to treat me as if I know nothing!

Thanks. I assumed that was the case but thought I should check!

My first two tasks failed after five and 3 minutes. I restarted the computer and 20 tasks are running beyond 40 minutes.

I have posted on the BOINC forums and it seems BOINC does not have write access to /tmp. I ran
 systemctl cat boinc-client.service
and the output included
 ProtectSystem=strict
ReadWritePaths=-/var/lib/boinc -/etc/boinc-client


And was told this:
That configuration makes the system read-only for BOINC, with few implicit or explicit exceptions. /tmp is none of those. You could override the configuration to allow /tmp but that would have to be done for every client. Or you could make the application developers aware that they are effectively restricted to the BOINC data directory.


For the average user instructions on how to override the configuration file will be needed but even if you provide these you will get a significant (possibly even a majority of users on Linux) who are set and forget so will crash a large number of tasks. CPDN has this problem with respect to 32bit libraries needed on Linux.

I used
 sudo systemctl edit boinc-client.service
to add /tmp to the read write paths.

Tasks running for longer 4 seconds instead of 1.something cpu time and around 50 seconds run time but still failing with
 195 (0x000000C3) EXIT_CHILD_FAILED


Edit: next stage might be to try it in a vm and change the line
ProtectSystem=strict

Now trying in a VM where I feel a little safer making some changes.

Still the same problem despite having removed the line

ProtectSystem=strict
I suspect there is something I don't understand about how to allow BOINC access to /tmp

I have in the vm added boinc to the root user group to see if that makes any difference but will have to wait till boinc communicates with the servers again.

Still all crashing with the same error. ran
~$ systemctl cat boinc-client.service
again and the same lines are still in the output so it clearly hasn't allowed write permission to the directory.
