Mooi'n,

I am trying to install Kubuntu 22.04.2 but the image that I find in
various locations is 5023979520 bytes (sha256sum matches) and all tools
that I try to use to burn the image (k3b, wodim, growisofs) complain
that it is way too big (correction: k3b does not complain, it just
doesn't allow to burn the image ;-) )

Do I need a DL DVD???

I've had problems with those. Maybe you could use a USB drive.

Do I need a DL DVD?
It has been YEARS since I burned an optical for a linux .iso. I have
stacks and stacks of old CDs w/ linux, and much smaller such dusty
collections of linux on DVD. I've put hundreds on USB since those days,
and currently my linux USBs are almost all Ventoy.

Is there any special reason you need to go optical?

Do I need a DL DVD?
It has been YEARS since I burned an optical for a linux .iso.  I have
stacks and stacks of old CDs w/ linux, and much smaller such dusty
collections of linux on DVD.
I have a disk (HDD) that I keep ISO images on and whatever I then need,
I burn onto a DVDRW, so I avoid having too much plastic lying around.
  I've put hundreds on USB since those days,
and currently my linux USBs are almost all Ventoy.
Is there any special reason you need to go optical?
No, as long as I can boot from the medium, I'm fine.
I hadn't been aware that one can boot an ISO from a USB stick.

Having said that ... I have now burned 20.04 (without the ".2") on the
RW and was about to install from that and have the installer pull in the
newer packages.

But I may try a stick, having several lying around.

Thanks,
Josef

Please find the time to do so. It is likely that 5GB Linux isos will become
more frequent. Sooner or later one has to move with the times.

As suggested Ventoy is your first port of call. However some iso fail to
boot from Ventoy, only a few. In this case Etcher is the second port of
call.

These are names that do not mean anything to me (Europe/Germany), so
I'll try a generic stick and go from there if that fails.

Thanks to all for enlightening me,

PS I have retired a few months ago. Before that I had colleagues that I
could just ask, this is much more difficult now.

re Ventoy:
Google / DuckDuck / etc. are your friends.
c.f. https://www.ventoy.net/en/index.html
Plenty of reading matter, HowTo etc.

Disclaimer: I have not tried Ub. 22.04 on ventoy, however I have succeded in booting Ub 20.04 from a USB stick.

As an added attraction, ventoy allows booting either with or without persistence, so that you can build your own
personalised system on a bootable stick.

Ventoy and Etcher aren't brands of USB sticks, but bootloaders which can
be installed on a USB stick, which in turn boot ISO files saved to the
stick. After installing the bootloader to a USB stick, you can just
copy ISO files onto the stick as normal files, and choose which one to
boot each time. It saves having to install just one ISO at a time onto
the stick, particularly when trying ISOs for different distros for
example, but it also makes it easy to just copy the ISO file for a new
version and boot it to try or install.

Pretty much any USB stick large enough to hold several ISO files should
do. The larger the drive, the more ISO files you'll be able to keep on
there to choose from when you boot it. A decent USB 3 stick should be
faster, assuming the PC also has a USB 3 port, but even a cheap USB 2
one would probably be faster than booting from DVD.

OK. I understand now. I guess I need to follow the course "How to use
Google for Noobs" :-(

The current state is that I have installed using a 20.04 DVD and then
updated all the packages. So far no major problems.

I do have a reasonably large collection of USB sticks (in various colors
;-) ) and I'll definitely give Ventoy and Etcher a try.

Thanks!

Post by Josef Moellers
The current Kubuntu 22.04.2 ISO is shown in Dolphin with around 4,7
GiB = gibibytes (5.023.979.520 bytes on my SSD). A
single-layer/single-sided DVD is 4,7 GB = gigabytes (4.700.000.000
bytes).
So the Kubuntu 22.04.2 ISO is too big for a single-sided/single-layer
DVD - you will have to use a double-layer DVD if you don't want to -
or cannot - boot from the suggested USB stick "burnt" with e.g.
Balena Etcher.

Besides the DL DVD and USB solutions, I just learned from that thread
that one can boot the .iso directly from grub 2.
Post by Mike Easter
Even better, once you have a functioning install you can boot the ISO
directly from GRUB
https://help.ubuntu.com/community/Grub2/ISOBoot
Post by Mike Easter
Ubuntu ISOs are designed to allow booting directly from the hard
drive using GRUB 2 and eliminates the need for burning a CD/DVD. This
feature permits the user to boot and use the "Try Ubuntu" feature of
the Ubuntu installation CD as well as to install Ubuntu directly from
an ISO on the hard drive. In addition to Ubuntu ISOs, many other
Linux distributions as well as popular rescue CDs can be booted
directly from an ISO file.

The image is too big for normal DVDs. It is much better to refuse
writing than start writing and waste the DVD.

Get a BluRay or much better, a USB flash disk.

The area of optical media is almost over.

Correct. What I was aiming at was that k3b doesn't tell why it will not
start burning, the "Start" button just stays grey. I would expect some
popup or at least an error message in the main window to tell me why it
will not burn.

Will do so.

True.
