title: TPM 2.0 - could not load "libtss2-tcti-tabrmd.so.0"
body: <p>I am trying to follow <a href="https://www.digitalocean.com/community/tutorials/how-to-set-up-an-ikev2-vpn-server-with-strongswan-on-ubuntu-20-04" rel="noreferrer">this guide</a> 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.</p>
  <blockquote>
  <p>kieran@azuracast:~$ pki --gen --type rsa --size 4096 --outform pem &gt;
  ~/pki/private/ca-key.pem<br />
  TPM 2.0 - could not load &quot;libtss2-tcti-tabrmd.so.0&quot;<br />
  plugin 'tpm': failed to load - tpm_plugin_create returned NULL<br />

  <p>It seems someone else in the comments was getting this but there are no replies.
  Any thoughts?</p>
