Then check if your boinc user account is available:
grep -i boinc /etc/passwd

If not, reinstall BOINC and reboot.
The computer details report 7.16.6.
Try to get a more recent version, preferably from your Linux vendor but avoid 7.18.1 since it is an Android only version.

grep -i boinc /etc/passwd

boinc:x:122:129:BOINC core client,,,:/var/lib/boinc-client:/usr/sbin/bash

That's the NEW PC client:
https://lhcathome.cern.ch/lhcathome/show_host_detail.php?hostid=10834344

P.S. I changed in the /etc/passwd those two lines: (I open the /etc as root and change the passwd file with notepad. Hope didn't do some bullsh*t)

1)
boinc:x:122:129:BOINC core client,,,:/var/lib/boinc-client:/usr/sbin/nologin to
boinc:x:122:129:BOINC core client,,,:/var/lib/boinc-client:/usr/sbin/bash

and
2)
_flatpak:x:126:136:Flatpak system-wide installation helper,,,:/nonexistent:/usr/sbin/nologin
_flatpak:x:126:136:Flatpak system-wide installation helper,,,:/nonexistent:/usr/sbin/bash

su: failed to execute /usr/sbin/bash: No such file or directory


Boinc(flatpak) version 7.22.1 (x64) is installed .

Changes to /etc/passwd don't make sense.
At least for user _flatpak since homedir is set to "/nonexistent".

Please post your BOINC service unit file to check if there are too many "hardening" options set.
Most likely /etc/systemd/system/boinc-client.service

No file there: /etc/systemd/system/boinc-client.service
but there is a file there: /etc/systemd/system/multi-user.target.wants/boinc-client.service

P.S. After that, you may write a whole book about ''how to configure BOINC and Virtualbox in linux mint 21.''

I got too tired trying to get the boinc service to work so I removed the ProtectSystem=strict, I just change to full and life is less stress.

looks like they just changed it back in the code also.

https://github.com/BOINC/boinc/issues/3355

Toby is right.
https://github.com/BOINC/boinc/blob/master/client/scripts/boinc-client.service.in
At the end BOINC changed the setting back to
ProtectSystem=full

@ stratos412
Your service file sets
ProtectSystem=strict

To solve this you may use an override file /etc/systemd/system/boinc-client.service.d/override.conf

[Service]
ProtectSystem=
ProtectSystem=full

Stop BOINC
run "systemctl daemon-reload"
Start BOINC

This is getting ridiculous..... :/

Open file: /etc/systemd/system/multi-user.target.wants/boinc-client.service (yesterday)
For some reason (today):
"The link boinc-client.service is broken. The link cannot be used because its target /lib/systemd/system/boinc-client.service does not exist"

Uninstall boinc(flatpak) / reboot PC twice / re-install boinc(flatpak) --> Same problem.
However, BOINC start fine and get tasks.

Someone is laughing at me...

----------------------------
Just a short story.
This remind me my first touch with Linux Mint 18.3 and I believe that's the reason why Linux is never going to win a windows average user.
(it is said that is a friendly version for a noob user who uses windows OS all his life).

I plug a usb stick to PC. It doesn't recognize it.
After some internet search I learn that I have to format the usb to an ext4 format. So far so good.
After a couple of days, I get an error "unable to mount usb stick. Not authorized to perform operation blalh blah...."
I wonder " what the hell?. Two days ago it worked fine. "
Search again on internet. Spent two days trying different things and keep notes what I have done, because I may break something.

At the end, I find a post that suggest to kill any process related to google-remote-desktop!
Try it and voila! Usb worked again!
I was yelling "Why the f*** google-remote-desktop interferes with my usb stick?!?!?. It doesn't make sense."

If you have to search around the internet for just those silly things, something in the OS must be wrong.
I installed BOINC in a windows machine and it didn't get more that 30 minutes to understand it and configure.
In the linux machine, I spent whole days with no result and after a major upgrade, thing getting worse.
----------------------------

I don't think the boinc team designed for Flatpak, if you install from repo then its same as windows, just install and it works.

BOINC flatpak runs fine. It is installed via Software Manager.

The problem is why I keep getting hard time.

A) Open file: /etc/systemd/system/multi-user.target.wants/boinc-client.service (yesterday)
For some reason (today):
"The link boinc-client.service is broken. The link cannot be used because its target /lib/systemd/system/boinc-client.service does not exist"

B) I cannot run any LCH task

C) Tried all the instruction of those posts and still nothing. Something is misconfigured?

D) Still cannot understand why NO virtualization for the same PC with different OS.

BOINC flatpak runs fine. It is installed via Software Manager.

Not sure if it does.
At least it doesn't report virtualization.

What you may try:
Get rid of flatpak and install the software you need on the plain Linux flavour you prefer (guess Linux Mint in your case).
Then use the non flatpak packages, especially for VirtualBox and BOINC.

@computezrmle

I had boinc-client and boinc-manager with Linux Mint 20.3 (boinc packages installed via terminal, following the steps of BOINC page setup)
Those were working fine, I also had the virtualization on linux PCs.
After the upgrade to linux mint 21, guess what. BOINC stop working. I just followed the steps for the upgrade. Didn't do any shortcuts.
This is the report from system reports. (Don't have a clue what's going on.I tried somethings from Linux mint forums referring to BOINC software but it didn't help).
The last thing I am thinking to do, is run BOINC on a virtual machine, trying some linux distributions and see what will happen.

Program terminated with signal SIGILL, Illegal instruction.

This usually happens if (1) you run a program that makes a call to a library which is not installed on your system or if (2) compiler flags have been used which generated code for a different CPU.

Here, the Linux upgrade might have changed some libs used by BOINC (especially boincmgr).
In most cases this is a wxwidgets issue, less often a libc issue.

Do some basic tests:
Change to the directory where your boinc executables are located (boinc, boinccmd, boincmgr).
There run "ldd boinc", "ldd boinccmd", "ldd boincmgr".
Check the output for errors or "not found".

If you don't find any errors, run "./boinc -h", "./boinccmd -h", "./boincmgr -h"
Check the output for errors.


In case the previous tests show errors, the BOINC package you are using was not made for the Linux version underneath.
If you got that BOINC package from an official repository of your Linux vendor, it would be their job to deliver a BOINC version linked against the correct libraries.

As a workaround you may install a BOINC version from Gianfranco Costamagna or via the Berkeley installer.
There's a long discussion at github about a similar issue.
Not exactly the same but you may get the global picture there as well as the links:
