Hello,

Every time I want to start from scratch on a new machine after a while I search for the steps that are needed to complete the installation on Ubuntu24 to get the Boinc Manager running.
Could you please collect these steps and stick it here in the forum to be found?
I just know that some access privileges needs to be fixed.

I use Ubuntu 24.04LTS and Boinc Manager version unknown (it does not start) - but it is the version from sudo apt-get install boinc

Thank you!
Magiceye

Two steps that always seem to do it for me are
1:Add yourself to the boinc group.
2: Haven't had to do this for some years but when the first failed I would give myself ownership of /var/lib/boinc
Last time I had to do that on Ubuntu the folder was /var/lib/boinc-client which it still is on some distributions.

Really someone needs to speak to the package maintainers for Ubuntu. I have taken to building from source for some years now which seems not to run into that problem.

All instructions are already here: https://boinc.berkeley.edu/linux_install.php
And this page is accessible from the main Download page

Sadly, those instructions do not tell the user what to do if a permissions or password issue means the manager does not connect to the client on a default installation following those instructions. This has plagued boinc on various distributions since I first started using it. I don't know enough to know whether there is a way to avoid this being introduced by the package maintainers? I assume that is the stage where the issue arises as I haven't experienced it when building from source?

Packages we maintain (from the instructions above) set all the required permissions.

Yet every month or so we get a post such as this one either from a new user or someone setting up a new box where it doesn't just work. Wouldn't it help to have the instruction on the install page to try

sudo usermod -aG boinc yourusername

if the manager doesn't connect to the client? I know I have had the issue many times over the years and seen the problem posted here and on project forums also.

On the install package we show instructions for our packages. And they don't require manual permissions to be applied. We made them exactly this way to simplify the life of our users. We can't put (and keep instructions updated) for every package manager that exists.
For others we have a very detailed instructions in out wiki: https://github.com/BOINC/boinc/wiki/Installing_BOINC_on_Debian_or_Ubuntu. It's hard to help people who cannot read.[/b]

Thanks Vitalii
I have bookmarked the git-hub link for next time I see the problem on CPDN forums.

I have found now the missing instructions (needed AFTER the installation). Maybe it helps someone or me in the future.

from: https://jerry.hear-me.blog/how-to-fix-three-obscure-boinc-problems-in-ubuntu-24-01/
(here all possible errors seems to be together in one place, not just one instruction here, one hint there, ...)

sudo usermod -a -G boinc <userid>
sudo chown boinc:boinc /var/lib/boinc/gui_rpc_auth.cfg
sudo chmod 640 /var/lib/boinc/gui_rpc_auth.cfg

Maybe some problems are based on ther very old boinc version that Ubuntu is using (7.24.1)

That is why we recommend installing our vanilla packages that don't have all these issues.
