I am not so naÃve to assume there was any way to prove my machine is not

My first assumption is that my machine is not compromised, and also
that the latest e2fsprogs you uploaded to Debian unstable and that
I installed on my machine does not contain a trojan added by someone
who hijacked your machine or your key.

There is no 100% security, only compromises between security and costs.
