Can't start any add-on, duplicate mount /dev/shm

2021.02.11, hassio in Docker
All worked before, then mosquito stopped, wouldn’t start again. Reboot server and all add-ons won’t start with the same error server 500, Linux mounts, duplicate mount /dev/shm

Seems docker related I’m running
Operating System
Ubuntu 16.04.6 LTS

Docker version
17.05.0-ce

The tempfs mount is seen in the host, but I can’t remove it as it’s busy.

Anyone have any suggestions?

Wasn’t getting much traction here and I had a few unsupported issues , didn’t like the OS or docker recently so I blew it all away thinking I’ll drop home assistant OS on a VM move a snap and boom all back yeah?

Well, yes all back, new problem home assistant OS don’t see my usb z-wave stick so can’t see it in hardware, it’s passed tho on the VM, like my old VM which worked ok for the old Ubuntu VM

I’ve given up on Home Assistant OS, USB isn’t seen, it is passed through on VirtualBox and It’s just a guess, I suspect this relates to the HAOS VM needing EFI, it won’t boot in legacy BIOS mode either.

My host is Oracle Solaris 11.2 that does other stuff I can’t easily move off right now (without new hardware) HAOS is ment to work out of the box but for me doesn’t so little point me going down that path.

Spun up the Ubuntu 16 VM I was using and having issues with and thought what the hell, I’ll upgrade docker and see where we are, I’ve got a running system again I can’t stay like this to be “Supported” and I can’t use the HAOS so looks like I’m going to have to do a debian install, then undo the openZwave I recently moved to and move it all again to the new JS thing

I’ve updated here as it might help someone else in a similar position, since I’ve chatted to myself it might be all the assistance that is available.
