I'm pushing out the installer for High Sierra with a policy. It's in a DMG to later be executed with startosinstall from Self Service.
Anyway I'm getting this error on a handful of machines and re-occuring over and over on some of the machines it's pushed to.
Downloading https://MYJAMFSERVER/Packages/Install%20macOS%20High%20Sierra.dmg... Verifying DMG... Verifying package integrity... Installing Install macOS High Sierra.dmg... Error: The package "Install macOS High Sierra.dmg" could not be mounted (no mountable file systems).
A lot of machines received it no problem, but a handful haven't with this error reoccurring. I thought maybe the connection was getting interrupted but it doesn't seem like that, if I SSH into a machine and execute the policy from the terminal I'll still see the error and never get booted from the SSH session. I don't believe I've ever seen this with other policies and packages before.
