I would have said you were living dangerously doing that.  The upgrade
path for LTS releases now only happens when the .1 release arrives. So
you would have to have forced the 18.04 to 20.04 upgrade, which is not
recommended until they have got all the bugs out of the process and
released 20.04.1.  That is for Ubuntu desktop though - is server the
same?

The PHP updating process really needs someone to produce an automated
upgrade system.  Your problem now happens every time the version
updates - it would be much better if the package had code to automate
the name change and maybe asked you if it could do it for you.  But
there can be other changes needed in the PHP code also, which is a
whole different ball game.  I had to modify the mythexport PHP code a
while ago when a PHP update broke it.  Fortunately the fix was pretty
obvious from the error messages, as I know nothing about PHP.

I find Snap updates to be a pain.  As far as I can tell, they do not
do any output to tell you what is happening.  So if there are 20 Snap
updates to be done, you just get to wait while it happens and you do
not even get told what has been updated.  It takes long enough with no
output that I always start to worry that something has hung, so I
usually go away and do something else so I will not be tempted to poke
at it.  I consider having no output to be a very stupid thing, as I
always want to know what has been updated so I can have some idea what
may have been broken by an update.
