Hello,

I am currently using BOINC 7.20.5 from the costamagnagianfranco PPA on an old PC (Core 2 Quad Q6600) with Ubuntu 20.04.

I would like to use this new feature to use 75% of the CPU cores when in use and 100% when not in use.

What is the recommended installation method for BOINC on Ubuntu for versions greater than 7.20.5?

Should I try the Flatpak version?

I also saw this: Bounty: Fix BOINC Linux Packaging which appears to be completed
I added the repo on my Pop OS 22.04 host:

wget -O- https://boinc.berkeley.edu/dl/linux/stable/jammy/boinc-202305.gpg | gpg --dearmor > boinc-key.gpg
cat boinc-key.gpg | sudo tee -a /usr/share/keyrings/boinc-key.gpg > /dev/null
echo 'deb [arch=amd64 signed-by=/usr/share/keyrings/boinc-key.gpg] https://boinc.berkeley.edu/dl/linux/stable/jammy/ jammy main' |  sudo tee -a /etc/apt/sources.list.d/boinc-official-test.list

There is only this one package in the repo, but I did not install it as it does not appear to be ready (weird version number etc.):

$ apt show boinc-linux-client

If you are happy compiling from source, that is the route I would go down. I have been running 7.25.0 built from the master branch on git-hub. this link gives a list of what I needed to install to get everything to compile successfully. You can also compile whatever the latest version for Linux is there.

I tried to use the repo as well but it is not fully deployed yet so Dave's is the best, once they are ready to use the repo they will let us know the Dev's said.
