Hello there 
Thatās interesting indeed! I couldnāt see the /var/foldersā¦ subfolder/path either on my Linux computer.
Perhaps that was just a temporary folder that was created (and got removed right away) when the backup/zip was extracted during the import process.
Was there any specific error shown in DevKinsta when it wonāt start (hanging on starting Docker)?
What if you check the recent/latest main.log file and see if you would see this in it?
[error] Error: connect ENOENT /var/run/docker.sock
If itās there, please try the suggestion/solution as shown here and here , and see if that would help?
Also, do you have any other sites created before in your Dockerās containers? if not, perhaps try to uninstall it completely and re-install Docker and re-load DevKinsta and see if it can start it properly?
Once everything is running fine again (both DevKinsta and Docker), please try to import the site from the backup file again.
If itās still not importing properly, I would suggest with an alternative/manual method as shown on our article/doc here.
Let us know how it goes.
Cheers,
Agus
