Boinc won't start after reboot.
If I completely reinstall Mint Linux and then reinstall boinc it starts with no problem and runs einstein@home perfectly..until I reboot for any reason.
Then boinc won't start.
Everything else runs...Firefox, Thunderbird, etc just not boinc

Boinc won't start after reboot.
If I completely reinstall Mint Linux and then reinstall boinc it starts with no problem and runs einstein@home perfectly..until I reboot for any reason.

I recently tried mint22.3 in a VM and didn't see this problem. It is possible I avoided this by compiling the latest master of 8.3.0 from source. Did you reboot with BOINC running? In your home directory is there a file BOINC MANAGER-steve There may be an underscore or hyphen between boinc and manager and hyphen after manager may be an underscore, I can't remember. If such a file exists, deleting it will let BOINC start normally. I won't check to see what the exact filename is at the moment because I don't want to risk losing the work that is running.

Boinc and einstein@home were running fine on this computer and had been for quite some time. I had some updates one of which was a new kernel. I installed the updates successfully. Afterwards boinc would no longer start. That was the beginning of this problem. I have rebooted, redone the update the problem still existed. I finally in desperation reinstalled mint linux. Then reinstalled boinc. Everything worked fine and I restated einstein@home. Everything worked fine until I did a reboot then I was back to the original problem boinc would no longer start.
