Please link me to the bug report for this issue as I have not had any
issues with mythweb when upgrading between mythtv versions (major or minor
versions).

Let me be absolutely clear, running an LTS version of Ubuntu does not mean
it is out of date. Further, it makes zero sense to upgrade something as
significant as the OS purely because there is a new version of Ubuntu
available (specifically when talking about appliance devices like MythTV
boxes). There is a reason that the Mythbuntu team only provides LTS
releases of Mythbuntu every 2 years and provides MythTV updates via the
MythTV updates repo for that LTS release. That reason is because for some
strange reason, people like to take a perfectly fine MythTV appliance, and
upgrade it for no other reason than a new Ubuntu version is out. For a
MythTV system, a new Ubuntu version offers nothing over an LTS release of
Mythbuntu. I can't think of a single reason that I would recommend
installing a non-LTS version of Ubuntu/Mythbuntu for a MythTV install.

My advice is to stick with the LTS release. When you want to upgrade to the
new MythTV version, switch to the appropriate MythTV update repo and just
upgrade the packages (not the OS). When the next LTS release is available
(eg. 14.04), I recommend a fresh install of that and copying over the
content you need (personally I keep my media on a separate drive so fresh
installs are easier). If you ever need to know what version of MythTV is
available for a particular Ubuntu version, check here
http://www.mythbuntu.org/repos . The graphic on that page is updated daily
and will always contain the correct information as to what version of
MythTV is available (from the Mythbuntu team) for which Ubuntu version.
