libsapi0 1.3.0-1 (amd64 binary) in ubuntu bionic

 TPM2.0 TSS (Software Stack) consists of API layers provided to support
 TPM 2.0 chips. It is made out of three layers:
 .
   - System API (SAPI), which implements the system layer API;
   - TPM Command Transmission Interface (TCTI), which is used by SAPI to
     allow communication with the TAB/RM layer;
 .
 This package contains the TSS and TCTI libraries that client applications
 will link against when they require accessing the TPM.
