Recently, I have found that BoincMgr is unable to run on my desktop computer. When I attempt to run it from the command line, I get an error that a segmentation fault occurred. Boinc itself is definitely continuing to run and launching at startup, as I can tell from htop and similar diagnostic tools. This appears to be a new development as of updating to Fedora 42, but I'm nonetheless unsure exactly when it started - it may have been slightly before or slightly after I updated from Fedora 40. If anyone has any suggestions, that would be great. Thank you!

Operating System: Fedora Linux 42 Worksation Edition, with Kernel 6.6.14-200.fc39.x86_64.

Boinc version: Obtained via Yum, version 8.0.2-2 according to the package name.

CPU: Intel i7-14700KF (28) @ 5.500GHz
GPU: Nvidia GeForce RTX 4070 Ti

GPU Driver version: 70.153.02

CPU Driver version: Unknown (sorry, not sure where to check this)

Odd. I can't see why the manager would be trying to access memory it isn't allowed to. I wouldn't advise running BOINC in this way but you could try starting it as root to see if that allows it to run as a diagnostic measure. Perhaps also try running memtest to ensure it isn't a hardware issue? Beyond that it will need someone with more programming experience than myself to work out what is happening!

Have you tried to install vanilla BOINC package instead?
We don't have a stable build yet for Fedora 42, but you can try our latest alpha: https://github.com/BOINC/boinc/wiki/Linux-DEB-and-RPM-support#for-fedora-41-42

I attempted to execute the following command as per the instructions linked by Vitalii Koshura, but ran into an error. The command I ran is as follows:

sudo dnf config-manager addrepo --from-repofile=https://boinc.berkeley.edu/dl/linux/[stable][alpha][nightly]/[fc41][fc42]

The error I receive is as follows:

Error in configuration file "/etc/yum.repos.d/fc42.repo.UBihVQ"
 Missing section header on line 1

Upon checking, not only is there a missing section header, but there is no file by the name `fc42.repo.xyz` in the directory at all! Notably, whatever came after the `repo.` changed each time I ran the command, though it was always six characters. I did a couple tests and found that dnf seems to be working just fine, able to update, add, and remove packages as one might expect. Is the command incorrect?

Ok, looks like the instructions are not so obvious.
Here's what you need to execute:

sudo dnf install dnf-plugins-core
sudo dnf config-manager addrepo --from-repofile=https://boinc.berkeley.edu/dl/linux/alpha/fc42
sudo dnf config-manager setopt boinc.berkeley.edu_dl_linux_alpha_fc42.enabled=1
sudo rpm --import https://boinc.berkeley.edu/dl/linux/alpha/fc42/boinc.gpg
dnf5 install boinc-client boinc-manager
