Failed Touch install on Oneplus 6

[ronbillock]

My Oneplus 6 is unlocked and in Developer mode, TWRP was run and installed. Everything was ready to flash Touch. I am on a Macbook with Ubuntu installed so I downloaded the Ubuntu (deb) download. I ran the download and connected the 1+6 and everything looked good, 1+6 was recognized, and the install process appeared almost complete, and then I received an error. I retried 3 times and received the error. Finally, the phone seemed stuck on the screen saying the bootloader was unlocked yada yada. I finally was able to get the 1+6 back into FastBoot Mode. When I try to rerun the Ubports installer it does not recognize the 1+6. The phone is now showing the Product_Name - sdm845. The Installer identifies that as the device. I tried self-selecting Oneplus 6 and run install and it errors off right away saying device is not recognized. I can't seem to get anywhere with the phone.

TRy this version of the installer or 0.8.9 https://github.com/ubports/ubports-installer/releases/tag/0.8.8-beta There is an issue with the latest installer not moving, if I have this right from fastboot to recovery mode a fix will be released shortly
