I forgot to start boinc using suda and it deleted all my work units. I am guessing that even though I am admin on m 18.04 box my apps cannot access "boinc" if they are started under my name.

Is it possible to recover the about 100 tasks?
I meant to started boinc with

sudo /usr/bin/boinc --gui_rpc_port 31418 --dir /home/jstateson/test --detach

but I left off the "suda" by mistake.

Use the "ghost task recovery protocol"

This was really difficult but I was able to obtain 2 out of 100 (or more) lost tasks.

I started a discussion about this over at boinc

You might want to put your 2c into that discussion as I mentioned you.

After reading Richards comments I will take your advice and not bother trying to recover those WUs.

One problem I found was when I am able to click the mouse at the correct instant, only those lost units that are within the "max runnable tasks" are recovered.

If I have a limit of 200 and there are 190 tasks on my system then the most I can get is 10. Unlike Milkyway, the seti project downloads a few tasks on every upload so the only way I can download a large number of lost units is to force NNT. However, if I am off by 1/2 second, I will simply get another 200 or so tasks and will have to wait several hours for a second try.

As Richard suggested, a mod to the client can be done to allow this to happen automatically, and he made a suggestion where that mode could go. My first guess was not correct but I could figure it out and build a special client but it is not worth the effort.
