Not sure where this post fits best, but I am sure it will be moved if better suited elsewhere.
I want to install UM 21.04 on a HP Envy X360 15 (Intel 7 & Nvidia)
I boot with the USB ISO... but then I get:
"error communicating with TPM chip"
I then get a whole numbered list (all named 'Nouveau')
then a 'Failed To create Kernel channel' error
then it stalls. Have to reboot to windows.
I did search the web for solutions. Most have the error post install. I can't even get there...
I've tried disable/enable TPM in the bios. I've tried 'factory reset' also. Nothing seems to work.
Can someone here can contribute a solution?
Many thanks !

Update:
I still get the messages above but a line before referring to "initramfs unpacking failed" or similar
then it goes through a system check and finally
Was able to boot from USB by going with the 2nd option, i.e. low graphic
But now with no touchscreen, no touchpad working. Only mouse and keyboard.
Would like to solve that before installing
Also I guess I should change driver for NVidia. But don't know which of the 4 I'm offered to take, i.e. 450 or 460.
Help still appreciated
Well....:
Maybe unrelated, but I had to reboot since I wanted to update my live USB. And now it doesn't show a choice of drivers in Software and Updates; no list. Still no pad and no touch.
and by the way, the USB has been made persistent and behaved well on another computer. Doesn't show as persistent on the Envy (!)
then... by reading on may sites, it seems that the issue may be RST-AHCI related. And nothing in the BIOS to change that.... If this is the actual issue. Still searching.
Help appreciated
