boinc-client won't start on Ubuntu 22.04

[Eric Levine]

Hi,

I'm running boinc 7.18.1+dfsg-4 on a VirtualBox Ubuntu 22.04 vm. I've noticed that in the past week or so, I am no longer able to start boinc-client. I can't even bring up the Usage message:

ejlevine@muon-ub22:~$ /usr/bin/boinccmd --help

Illegal instruction (core dumped)

It seems to be related to libboinc.so.7.18.1; from /var/log/kern.log:

I don't see this file under /var.  I tried un-/re-installing the boinc packages, but that didn't help. I also found this bug report from Feb 2022:

Did something change recently?
