Hello.

I strongly recommend upgrading from 20.04 to 20.10.

I found 20.04 to be quite buggy, and, 20.10 was what 20.04.1 should
have been - a bug fix release

I have found 20.10 much better than 20.04.

For the upgrading, I changed the Software Updater setting (Software
Updater -> Settings -> Updates option "Notify me of a new Ubuntu
version" from "For long-term support versions" to "For any new
version", then closed the Software Updater, and ran it, and, when it
displayed the message worded like "You are running 20.04. A new
version, 20.10 is available.", I selected the "Upgrade now" option,
rather than the "Okay" option (the "Okay" option just indicates
acknowledgement of the message that a later version is available), and
then, it commenced the upgrade to the newer version.

All applications were upgraded as appropriate, and, no files or
folders were needed to be copied; it upgraded the 20.04 installation
to the 20.10 installation, and, no configuration files needed to be
copied to the new version installation. Even the compound update
command, that has previously been discussed (it contains about four
commands, in a single command, to perform a system update), was still
stored in the command history, so, simply using the upward arrow (as
opposed to, I think it is named, the up arrow; the ^ character), to go
back through the command history, at the command line, brought the
compound command back, for reuse, for subsequent system updates.

Regarding the problem that I encountered with the last update (not
associated with the version upgrade to 20.10, from 20.04 - that needs
to be emphasised, for clarity), with wifi access to the Internet, I am
still investigating it; it may have been coincidental, as, in
switching to my secondary modem using the same 4G carrier, it is
working okay. I had tried to minimise usage of the secondary wifi
modem router, to try to avoid interference with, and, therefore,
disruption to, the wifi data uploading via the Internet, of my
domestic rooftop photovoltaic system inverter, the data output of
which, I record daily, for monitoring its performance, via
screenshots.

I do not know how all of this works, with Ubuntu Studio, in terms of
version upgrades, but, I tend to regard the version upgrades, much the
same as normal system updates (apart from for my 16.04 system, as I
regard the versions after 16.04, to be significant downgrades from
16.04), in that I just perform them without doing anything to the
existing system, to adapt to them. With kernel (and associated
packages - it usually totals about 70MB) updates, I tend to leave them
until I get a system crash or something, due to having to reboot, and
the consequential day or so, taken up, in trying to get the system
restored to its status before the kernel updates.
