Simon, As per above, dnsmasq routinely fails to respond to a DHCP request, which breaks autopkgtest for other packages on a random basis. While I have marked the test as flaky, as per Luca's suggestion, as a temporary kuldge, I'd really like to get to the bottom of what causes these random timeouts. The test I'm currently using is as follows: https://salsa.debian.org/debian/dhcpcd/-/blob/debian/sid/debian/tests/timesyncd-ntp-servers-from-dhcp?ref_type=heads Given the above, can you think of any reason why DHCP would randomly fail to respond within dhcpcd's default 30 seconds timeout? Thanks! Martin-Éric
