See the sentence you quoted: "If this 'Other' computer also has

Ubuntu 18.04

installed on it you can do:". Yes, the presumption is that the

networked

machine is running the same release as the non-networked machine.

While a release model distro isn't that sensitive regarding partial
upgrades, it still inherits a risk. If the install that isn't

connected

to the Internet has got different additional packages installed,

than

the install connected to the Internet, a partial upgrade is risky.

I'm presuming that the two machines are kept pretty much in sync, at
least as
far as the base packages (especially things like common libraries and
core
utilities) are concerned. Have a bit of diversion amoungst optional
application packages probably is not going to matter.

IOW the same Ubuntu release needs to be a default Ubuntu install

without

any additional package installed or both installs need to have the

same

additional packages installed and the cache of the machine installed

to

the Internet must contain all of them. If so, it's required to do a
full-upgrade. If not, there potentially is a risk that a partial

upgrade

breaks the install. This risk isn't that critical as for a rolling
release model distro, but even for a release model distro there at

least

is a minimal insecurity doing partial upgrades.
"Minimal insecure" is similar to "a little bit pregnant", it's not a
matter of value.

If Oliver, Robert, Tom or Ralf would upgrade gcc by this thumb drive
approach it would be ok, but if somebody needs to sent a request to a
mailing list in the first place, I tend to recommend against doing
such
an upgrade, just for the "you never know how incomplete the request
already is" reason.
At least we should mention, to backup the install (not just /home)
before upgrading gcc this way.

This most, most, most likely true! _But_ even while much, much, much
unlikely, it isn't necessarily true. Then keyword remains "probably".

Yes, there is always going to be possible problems. This sort of
situation is
poorly handled/supported by Debian in general and Ubuntu in partitular
--
Debian/Ubuntu is pretty much geared towards machines that are
connected to
Internet with a decent bandwidth.
RHEL on the otherhand, uses install media containing a complete
repository and
creating a local mirror of updates is a trivial matter of rsync'ing
the
repository to removable media. This makes RHEL (and CentOS/Scientific
Linux)
the ideal choice for a machine that is either off the Internet or
connected
poorly to the Internet (like my home machine with only a Dialup
Connection).
I'd would really like to recomend to the OP to NOT install any verison
of
Ubuntu on a non-Internet connected machine.

I'd would really like to recomend to the OP to NOT install any

verison

of Ubuntu on a non-Internet connected machine.

My "main" install is Arch Linux, a real rolling release and my "you
never know what happens to Arch Linux 'backup'" install is an Ubuntu
LTS
install.
I agree, that in most cases it's way better to use Ubuntu with an
Internet connection, let alone a rolling release such as Arch Linux
and
without doubts upgrading gcc works assuming the conditions you assume
are fulfilled.
However, why does the OP need an upgrade of gcc within the Ubuntu
release model distro policy only?
IMO it's fishy. A security upgrade makes sense, a feature upgrade
doesn't make sense. IOW, why is an upgrade of gcc only required for a
machine that isn't connected to the Internet?

It is possible that the machine originally had a 'minimual' install
and so is
missing build-esentials. It also possible the OP is someplace that
lacks
"Real" Internet. Like, for example, Western Mass. *I* live in a town
(in
Western Mass) where there is no DSL, no cable provider, and spottly
cell
coverage. *I* have dialup Internet at home (which I have to throttle
down to
33KBPS, since the phone lines are crap and are not really up to spec
(cannot
reliable handle V.90). Yes, there really are places like that, mostly
in
rural USA. From an Internet Access POV, the USA has become a "third
world
country".

Subject: bluetooth not working, v18.10
Content-Type: text/plain; charset="utf-8"; Format="flowed"
Hi there
I have v18.10 running on an DELL xps15.
I can not get any bluetooth device running.
The only device that is offered in the settings dialog is a nearby
blue tooth not connecting
but I can not do anything with it.
Sometimes when I switch on and of bluetooth devices nearby, I get one
or
more unnamed devices listed, with which I can not do anything neither.
The devices work well, when I run windows.
can anybody give me a hint what to do?
thanks
robert

Oh, I actually want to program in c language on a computer without a network, so I won't be distracted to do other things, and I will learn C language with one heart and one mind.

Ubuntu18.04 LTS offline installation via Iso image Is there a gcc compiler? Can I use it? I think the distribution has built-in gcc, because built-in gcc to compile the kernel.?

Hi,

First, a point of mailing-list etiquette. When replying toa "digest"
message, delete the text that isn't relevant to your query.

How much coding experience do you have? What do you already know - about
Linux, computers, and C?

It has been a long time since I learned C so I don't know which resources
to recommend to you. I do have some links to gcc documentation - but I am
not sure that would be much help. As an experiment, I tried Googling for
"learning C" and came up with some likely results.

HTH,
