Stacy Webb changed the script yesterday to address this issue. I’ve tested it with a clean install, but still it didn’t work.
I have to try and manually install and see where there’s a problem.
Only my knowledge of Linux is not that good at this point in time.

@kennetht To bad that there is no response to this issue.
Although I have little to no knowledge on how to solve this, my gut feeling tells me some install script needs to be updated and pointed to a newer electron installation.

@stacywebb On a Rock64 with Jessie installed and updated the automatic installer halts on the Chromium install.
Is there a newer script available or any help?

Is there any progress or different approach available for an installation on a Rock64?
Both 7.0 and 7.1 of the chromium webdrivwr are unavailable.

Love to have this working on the Rock64.
