Libreoffice execl failed: No such file or directory

Host is ubuntu 18.04 (beta). I was running libreoffice from snap w/o trouble for last month+. Today (after a apt update on host), it no longer works (even w/ uninstall/reinstall).

$ snap list

don@office:/var/log$ libreoffice
execl failed: No such file or directory
child exited with status 1

If i strace:

sudo strace -s8192 -e file -f libreoffice
openat(AT_FDCWD, "/sys/devices/virtual/mem/null/uevent", O_RDONLY|O_CLOEXEC) = 4
strace: Process 15997 attached
[pid 15997] execve("/usr/lib/snapd/snap-device-helper", ["/usr/lib/snapd/snap-device-helper", "add", "snap_libreoffice_libreoffice", "/sys/class/mem/null", "1:3"], 0x7ffe7a438458 /* 0 vars */) = -1 ENOENT (No such file or directory)

I’m not sure what to do to debug this. Any suggestion?

this is … it is being worked on atm …
