Crashed as I was trying to use the on-screen keyboard to type in random letters and numbers of the wifi password, because I couldn't select DVORAK keyboard layout yet.

Thanks for your report.
I cannot reproduce your issue. If you can, can you please provide all the steps to do it.
Besides I noticed the following error message in yor log files:
Sep 12 00:34:50 ubuntu-mate kernel: [ 975.913476] SQUASHFS error: zlib decompression failed, data probably corrupt
Sep 12 00:34:50 ubuntu-mate kernel: [ 975.913486] SQUASHFS error: squashfs_read_data failed to read block 0x711a8b0
Sep 12 00:34:50 ubuntu-mate kernel: [ 975.915603] SQUASHFS error: zlib decompression failed, data probably corrupt
Sep 12 00:34:50 ubuntu-mate kernel: [ 975.915607] SQUASHFS error: squashfs_read_data failed to read block 0x711a8b0
Which suggest that the installation media is corrupted and is more likely te cause of the failure you observed.
