Title:
Upgrade to kernel version 4.4.0-66 of Ubuntu 16.04 LTS caused major
chaos/failures
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Xenial:
Confirmed
Bug description:
The most obvious issue upon logging in was that there were no network
interfaces save the loopback.
A review of the logs suggested there were many major problems with the
upgrade.
Interestingly, the system suggested that I delete all other versions
of the kernel immediately after this failed upgrade. This would have
rendered the system nearly unusable.
This is not the user experience I was thinking of when I chose an LTS
version.
