I tried various workarounds for autopkgtest testbeds -- we *really* don't care for good random numbers there, and this causes awful delays in various tests.
https://github.com/openstack-infra/project- config/blob/master/nodepool/elements/initialize- urandom/static/usr/local/bin/initialize-urandom.py has a very good explanation of how the urandom pool is initialized. Based on that, this unit drop-in speeds up urandom initialization by fake entropy: # /etc/systemd/system/systemd-random-seed.service.d/fakeentropy.conf [Service] ExecStart=/usr/bin/perl -E 'open $$f, "/bin/bash" or die; open $$rnd, ">/dev/random" or die; for ($$i = 0; $$i < 10; ++$$i) {read $$f, $$d, 64; ioctl $$rnd, 0x40085203, pack("ii", 64*8, 64) . $$d}' ** Also affects: auto-package-testing Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1622893 Title: NetworkManager takes very log to start, or times out, blocked on RNG Status in Auto Package Testing: In Progress Status in gnutls28 package in Ubuntu: Triaged Status in network-manager package in Ubuntu: New Bug description: Since a few days ago, NetworkManager.service takes awfully long to start, or even times out on failure and then gets restarted. This happens in a 16.10 desktop amd64 installation in QEMU, or e. g. in the systemd "boot-smoke" autopkgtest where every boot takes > 1:30 minutes due to the NM timeout. In the journal there is no actual logging from /usr/sbin/NetworkManager yet, just the start timeout.
