Here's a one liner that *doesn't require root* that you can use to test whether the kernel fix has landed:

unshare -rUn sh -c 'ip link add dummy1 type dummy && ip link set dummy1 up && ip -6 route add default dev dummy1 && ip -6 rule add table main suppress_prefixlength 0 && ping -f 1234::1'

Note: this will crash your system.

Fix submitted: https://lists.ubuntu.com/archives/kernel-team/2019-October/104623.html

Since we're just about one week from the release of Eoan, this fix may not make the Eoan release. If that's the case, it will be included in the initial set of Stable Release Updates (SRU) for the Eoan kernels.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-eoan' to 'verification-done-eoan'. If the problem still exists, change the tag 'verification-needed-eoan' to 'verification-failed-eoan'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

The proposed kernel works fine, tested with wireguard on multiple systems and the one liner mentioned in #4 does not crash the system.
