using above to restore data after snap version upgrade and detecting that from snap wrapper script but snap does work so its getting core dump on terminal or is it not good way to do this via wrapper.

Are there security policy denials? You can see with:

$ sudo snap install snappy-debug
$ sudo snappy-debug.security scanlog

That said, I suspect it is going to report the following:

don't copy ownership of files (eg, use 'cp -r -preserve=mode' instead of 'cp -a')

Yep it did and I pretty much forgot to check for denials :expressionless:

Suggestions:
* don't copy ownership of files (eg, use 'cp -r --preserve=mode' instead of 'cp -a')
* try the snapcraft preload plugin: https://github.com/sergiusens/snapcraft-preload
* adjust program to not use 'lchown'

well I’m now using cp -r --preserve=mode instead of mv solves this issue.
