I am getting the following error message as a list of 4 or 5 lines with differing numbers at the beginning of each line during boot for a long while:
ima: error communicating to tpm chip
I am using Ubuntu 19.04 (though this error was existing for a while at the older versions) and my computer is a Toshiba Z930.

It is simple: just enable TPM from the BIOS setup.
To change the BIOS settings you can hit F2 during boot before Ubuntu starts. Please be sure not to change anything else if your computer is working properly.
