I should make myself a bit clearer. the program may be running, but I have no idea of how to use it unless the graphical user interface (gui) shows up. That does not happen and unless I have copy and paste instructions, I am helpless to make it work. So far I was using that which I found on the website and that which I could understand from other sources. So, until the gui becomes available to me, boinc is not working. I do not know why the gui does not load as it has always been available until the system upgrade. I hope this explains my problem sufficiently to suggest a solution.

I even tried running boinc-manager from the terminal.

james:~$ man boinc-manager
No manual entry for boinc-manager
james:~$ boinc-manager

BOINC 7.18 is for Android versions only, it's not suitable to run on Linux.

Report that to your package maintainer and return to a previous version. Tell them to use branch 7.20 or 7.22 to make their package.

The repository I am able to access does not have the versions you indicate and I have no idea where to acquire them. I appreciate the information and I will make the attempt again when the appropriate version is available to me. In the mean time, I purged boinc from the system using

sudo apt purge boinc*

and I will check back when I next have time to see if there is a suggestion of where to acquire the appropriate version of boinc for linux mint.

Managed to purge before loading from the new repository.
Similar problem in that I had to execute the manager from the terminal. The manager says it is unable to open the client. While the graphical user interface (gui) is visible, it does not connect to the internet and none of the functions I tried had any effect.

I did manage to get some results by executing the client first then the manager from the terminal. A work around at best, but at least it seems to work. The connection was deferred so I have yet to see any tasks loaded to be executed.

Seems to be functioning normally now that I have some active tasks. Thank you for your assistance.

Not sure why you installed the Nvidia drivers in your previous attempt when you don't have an Nvidia card. Your video drivers need to be by AMD.

Redo your group addition from your previous attempt. Should clear the Manager connecting to the client issue.

sudo usermod -aG boinc james

Never noticed until I had a problem.

sudo usermod -aG boinc james

The thought never crossed my mind. Did not know it was that important to my problem. The description seemed to indicate that the only function was to limit access. In any case, this allows me to just click and get things going. I would say that your suggestion solved the problem I was having. Thank you.

I used the code you posted. After a reboot, I was able to launch BOINC from the menu.
