Hi, to day in a Debian system I upgraded some packages.
After the MM3 doesn't start anymore.

Some fairly recent Linux manpage I saw on the web says for kill(2) (ie, the system call in the kernel):
If sig is 0, then no signal is sent, but existence and permission
checks are still performed; this can be used to check for the
existence of a process ID or process group ID that the caller is
permitted to signal.It appears that for some reason you are no longer allowed to send a signal to the master subprocess watcher to find out if it is running.
Just a wild guess, so I hope you get better information, but I would start looking at the packages below. Check its docs in /usr/share/ to see if there's a NEWS file or ChangeLog that helps.
[UPGRADE] qemu-guest-agent:amd64 1:3.1+dfsg-8+deb10u5 -> 1:3.1+dfsg-8+deb10u6
