Because I have a Windows system I tried with "bootra1n" (usb stick). With this I get to the second step (watir for trigger) but after few minutes nothings happens and some error message appear. But I red somwhere about a replug trick. I retried the method with bootra1n and wait 2 minutes (wait trigger). Then unplug und plug the iPad very quick ... The jailbreak process bar continues and the jailbreak is successfuly :)

Checkra1n doesn’t work in a vm properly because u have to keep allowing usb pass through for Apple Dfu , recovery mode, normal mode

[Sandwhich253989]

Even for me it didn’t work in a vm but in Ubuntu bootable usb , checkra1n works perfectly

See #1.
In order for a VM to even have a chance of working, you need USB passthrough. Windows doesn't support that.
