I have just installed Ubuntu 20.04.01 LTS on to an old MacBook Pro 7.1, I followed the instruction on installing Ubuntu as the only operating system and all went well with no error but on booting the new installation I get the following errors.
Failed to set MoKlistRT: Invalid Parameter
Could not create MoKlates has failed: import_mok_state0 failed
: Invalid Parameter
Continuing boot since secure mode is disabled
System then gives a blank screen and hangs.
Any help will be appreciated.
