I am trying to follow this guide and am not getting very far. I am using a pretty basic digital ocean VPS running latest ubuntu 20.04, and am getting this error when trying to create the certificate authority.
kieran@azuracast:~$ pki --gen --type rsa --size 4096 --outform pem > ~/pki/private/ca-key.pem
TPM 2.0 - could not load "libtss2-tcti-tabrmd.so.0"
plugin 'tpm': failed to load - tpm_plugin_create returned NULL
kieran@azuracast:~$
It seems someone else in the comments was getting this but there are no replies. Any thoughts?
