Thanks, that worked better. Even so, the result of GPG verification is not what I expect:
Untrusted signature
.0xB10C <0xb10c@gmail.com>
0CCB AAFD 76A2 ECE2 CCD3 141D E2FF D5B1 D88C A97D
From what I understand it's expected that file is signed by Wladimir van der Laan. Trying to be a responsible citizen here.
