[Bug 1728355] Re: An unsolvable problem occurred during the calculation of the feedrate.

[Brian Murray]

Although lsb-release indicates you are running zesty, your
/etc/apt/sources.list file is composed for entries for xenial (Ubuntu
16.04). This causes the upgrader to fail to calculate the upgrade.
Please either change your sources.list file to zesty or downgrade the
version of lsb-release to the one in Ubuntu 16.04.
