Ubiquity install wizard crashes; cannot install ubuntu-MATE 18.04.4

I’ve tried several times now to install Ubuntu-MATE version 1804.4 from a live USB.

Every time I hit “install,” nothing happens. A circle spins for a few seconds, then stops.

I get an error message saying that ubiquity has crashed.

In the terminal I checked for ubiquity using:


dpkg -l ubuiquity 
sudo apt update
sudo apt install ubiquity

and saw that the live USB already has the latest version of ubuquity, which is

I have a System76 Wild Dog, 64-bit desktop workstation, 4-core Q9650 3GHz, 8 GB ram. It has a BIOS, not UEFI.

Graphics: PNY Nvidia GeForce GTS 450, driver v. 367.44.
OSs: Ubuntu-MATE 16.04 & 14.04. Drives: 2 960-GB Sandisk SSDs.

I want to install Ubuntu-MATE 18.04.4 onto one of the SSDs (A standalone 960-GB SSD in an enclosure, that I later want to move into the Desktop box and boot directly from.)

Here is some of the lengthy error message report:




ubiquity crashed with PermissionError in___init___(): [Errno 13]
Permission denied ‘/cdrom/.disk/info’

How can I get a functioning ubiquity in the live USB and get the install wizard to open so I can complete the installation?
