This happened during UBUNTU MATE system installation on Raspberry Pi 4B 8GB.

[Piotr Grabowski]

This was my first system installation on newly bought Raspberry Pi 4 8GB. I used SanDisk 64 GB ULTRA memory card with Ubuntu Mate 64 bit system for Raspberry Pi 4 downloaded from Ubuntu site and unpacked into the card. I could not end the installation. However this is not the first issue with my Raspberry - on previous night I tried to use SD card, SanDisk EDGE 32GB, from Botland with NOOBs system but it did not work. I got some information displayed on the screen but NOOBs did not get installed, I could not use neither USB keyboard nor my wireless mouse (I can use both now).
I shall try to load the system again into the SD card with 7ZIP and I hope it will fianlly work.
As SD card is rather slow I would be happy to boot the system from USB disk as a much better option - I hope it will be possible soon.
I do not write write computer programs, I am a computer user who did not want to surf the net with "standard" computer with 500W power supply - the 20W Raspberry Pi 4 is a much better choice - if it works.
