If you are planning to actually upgrade the 14.04 system, rather than
do a new install of 20.04 daily, then you have to do the upgrades in
between anyway: 14.04 => 16.04 => 18.04 => 20.04.  And the LTS upgrade
code is not normally available until the .1 version anyway, so 18.04
=> 20.04.1 and 20.04.1 will not be available for several weeks after
the release of 20.04.  So realistically, you can only upgrade to 18.04
at present.  If you really, really want to use 20.04 at this stage
when it is guaranteed to still be very buggy, your only options are a
new install, or do the LTS upgrades to 18.04 and then upgrade 18.04 =>
18.10 => 19.04 => 19.10 => 20.04.

And you need to be wary of kernels as recent as the ones that are in
20.04 daily as they may well break your tuners - there have had to be
patches for broken tuner support in some recent kernels (in 19.10 I
think - I did not follow what happened except in passing).

What video card are you using?  If you have an ancient (now
unsupported) Nvidia chipset, then you can not upgrade beyond 16.04
anyway as the older kernels in 16.04 are the last ones that the old
Nvidia drivers work with.  Even in 16.04 you would have had to stop
upgrading the kernel months ago to keep the necessary Nvidia support,
or manually patch and install the old Nvidia drivers.
