When installing tpm-emulator as a dependency for another packages with pkg: [2/49] Installing tpm-emulator-0.7.4_2... ===> Creating groups. Using existing group '_tss'. ===> Creating users Creating user '_tss' with uid '601'. pw: user '_tss' disappeared during update pkg: PRE-INSTALL script failed
I'm not sure why this is occurring, but doing: pwd_mkdb -p /etc/master.passwd pwd_mkdb /etc/master.passwd will fix the issue.
