I noticed the other day that my CPU was running near zero rather than near 100%, indicating BOINC tasks had stopped. I got time today to check into it beyond that level and discovered that I have one Einstein GPU task that seems to have been static for about three weeks, and a bunch (probably my usual buffer of two days of work units) of MilkyWay CPU tasks that show "ready to report" but haven't been uploaded and replaced with fresh tasks.

The only notifications I see in BOINC Manager are one from Einstein warning me that my settings don't allow downloading CPU tasks and one from MilkyWay warning that my settings don't allow downloading GPU tasks; this is intentional, to keep them from competing with each other.

In the past, I've had computation stops because of my disk settings (over time, I have to adjust these as free space on my system partition changes -- which begs the question of why BOINC for Linux defaults to putting its disk storage in the system volume) -- but now I find the "Disk" tab displays no pie chart; I see just a small place holder square in the upper left of that tab, and I don't have the options that I'm used to seeing. This suggests something is broken in the BOINC manager (if the tasks situation didn't already).

My installed BOINC Manager version is Linux 64-bit 7.16.6, on Kubuntu 20.04, kept up to date (and I haven't had an error message during a system update in several weeks). I'm running an AMD FX8350 CPU, nVidia GTx750 with 1 GB VRAM on 460.73.01 proprietary driver, kept updated automatically; I have 16 GB RAM and a 250 GB SSD containing my system volume, /home, swap, and a couple other partitions (plus a 1 TB platter drive with a bunch of legacy stuff from Windows XP). Everything else seems to run well; my system has been restarted due to OS updates several times since the last confirmed task updates.

I have tried

sudo apt install --reinstall boinc-client boinc-client-opencl boinc-manager libboinc7

(and subsequently purged boinc-client-opencl after realizing it was AMD graphics specific), no change.

I'm not a power user by any stretch, neither of Kubuntu nor of BOINC; if you need logs please include information on where/how to find them.

Milkyway has some technical issues and hasn't been sending out work for sometime

That, however, shouldn't affect my Einstein tasks -- of which I have only one on the machine, which expired the 27th of April. Further, unless the server is completely offline, I shouldn't see completed tasks just sitting on my machine, even if there are no fresh ones to download -- right?

Edit: Okay, I aborted the long-overdue Einstein task, and I'm now getting downloads of new tasks for that project. That still doesn't explain or fix the problem with the "Disk" tab not displaying anything...
