I get a 404 error every time.

sudo curl -fsSL https://boinc.berkeley.edu/dl/linux/stable/$(lsb_release -cs)/boinc.gpg | sudo gpg --dearmor -o /etc/apt/keyrings/boinc.gpg

First thing to verify would be what "lsb_release -cs" says.

You are using a command for an OS that isn't officially supported (as you may mention, on the website we have Fedora, openSUSE, Debian and Ubuntu listed, there is no Mint among them).
However, you might also know, that Mint can use Ubuntu repositories to install packages, for this you need to find out what is the Ubuntu release name that was used to work your version of Mint, and then use the above command like that:

sudo curl -fsSL https://boinc.berkeley.edu/dl/linux/stable/UBUNTU_RELEASE_CODENAME/boinc.gpg | sudo gpg --dearmor -o /etc/apt/keyrings/boinc.gpg

I don't know what to put in and BOINC is not clear on how to do it. lsb what?
When Linux is so hard to understand BOINC should be more clearer on how to install it.

Something like this? But I don't know what CODENAME? If any of this so far is right.

sudo curl -fsSL https://boinc.berkeley.edu/dl/linux/stable/Ubuntu 24.04 CODENAME?/boinc.gpg | sudo gpg --dearmor -o /etc/apt/keyrings/boinc.gpg

Mint 22.1 is based on Ubuntu 24.04 LTS, which is called Noble Numbat (WTF do they give them these ridiculous names???), so i'm guessing

sudo curl -fsSL https://boinc.berkeley.edu/dl/linux/stable/Noble Numbat/boinc.gpg | sudo gpg --dearmor -o /etc/apt/keyrings/boinc.gpg

might do the job.

Ok, I got it now. And it seems I have to repeat it in the second line of code.

To be more precise:

sudo curl -fsSL https://boinc.berkeley.edu/dl/linux/stable/noble/boinc.gpg | sudo gpg --dearmor -o /etc/apt/keyrings/boinc.gpg

Maybe $(lsb_release -cs) is web base command to change the command line when selecting OS is not working. Because selecting OS does not change the command line when selecting it.
Anyway I got it installed.

This command works when you have an OS listed on the webpage.

No it doesn't. Why you think it says $(lsb_release -cs) instead of "noble" in it's place.
This is the only site that you have to edit instead of just copy and past and it just worked.

Have you ever tried to execute that command on Ubuntu 24.04?
Like literally: just copy paste and execute?

Yes, but the site is broken. But not it seems to be fixed but something still doesn't look right.
Where it says noble in the command is fixed. It didn't use to say that before. It had $ and ( ) with -CS instead.
Linux doesn't use $ or ( ) in the terminal. Am I wrong?

sudo curl -fsSL https://boinc.berkeley.edu/dl/linux/stable/noble/boinc.gpg | sudo gpg --dearmor -o /etc/apt/keyrings/boinc.gpg

The second command doesn't look right.

sudo echo deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/boinc.gpg] https://boinc.berkeley.edu/dl/linux/stable/noble noble main | sudo tee /etc/apt/sources.list.d/boinc.list > /dev/null

You are wrong. In this way we execute command inside the command to instantiate the variable.

Have you ever tried to run command as are they written on the web-site? Because they were tested (every on them for every distro) and there was never any issue.
Try to not overcomplicate it and trust the instructions written on the website.
