The first thing I'd do is some searching on the Internet.

By following the instructions available on the Debian web site (1)!

In a nutshell, change 'buster/stable' to 'bullseye/unstable' in
/etc/apt/sources.list'.:

$ apt-get update && apt-get full-upgrade


Note that you can also use 'apt' instead of 'apt-get'.

Do not  do this blindly on a production server though.

Not totally true though. There have been a few changes.
So if you just replace buster with bullseye it might not work.


Here is an example of an working bullseye sources.list

Should have been 'testing' and not 'unstable'.

In addition to Henning Follmann <hfollmann@itcfollmann.com>'s answer:

On buster the '/etc/apt/sources.list' file might look like:

"deb http://deb.debian.org/debian buster main
deb-src http://deb.debian.org/debian buster main

deb http://deb.debian.org/debian-security buster/updates main
deb-src http://deb.debian.org/debian-security buster/updates main

# buster-updates, previously known as 'volatile'
deb http://deb.debian.org/debian buster-updates main
deb-src http://deb.debian.org/debian buster-updates main"

And on Bullseye:

"deb http://deb.debian.org/debian bullseye main
deb-src http://deb.debian.org/debian bullseye main

deb http://deb.debian.org/debian-security bullseye-security main
deb-src http://deb.debian.org/debian-security bullseye-security main"


Mind the security lines!

Hi Wil,

Don't - at least not directly.

If your /etc/apt/sources.list says "stable" anywhere in it, you probably 
want to change that to reference "buster" today, anyway. Bullseye - Debian 11 -
is likely to be released within 8 weeks and will become the new "stable" immediately - 
at whihc point, there will be a huge amount of package churn.

If you want to update to what is _currently_ Debian testing - now is a 
relatively safe time to do so because it's in a state of freeze before it 
is released as Debian 11. Look at the release notes for Bullseye and the
posts on Debian Planet for "what's new in Bullseye" and update carefully.
[Change /etc/apt/sources.list to suit: apt-get update ; apt-get upgrade ; 
apt-get autoremove ; apt-get dist-upgrade ; apt-get autoremove is one 
sequence that will get you there.

if you want to upgrade to what will be the new Testing, I'd honestly suggest
waiting six weeks or so, upgrading to Bullseye as it comes out and _then_ 
upgrading to Bookworm.

There's information on Debian codenames and also "Which Debian distribution
should I use" on the Debian wiki at wiki.debian.org. 

In general terms: if you can't handle breakage, which may occasionally last 
for weeks or months, don't run Testing until you are happy troubleshooting 
and dealing with upgrading/holding versions of packages. 

The package churn on testing is correspondingly higher and there is no 
particular security support.

Just my €0.02

All the best, as ever

Hey there,

medal.

	The above is the best advice anyone could get in regards to
upgrading to testing or not.

> Just my €0.02

	Honestly worth a lot more.

	There are a lot of people that are not that familiar with Debian,
and sometimes it's comprehensible that they don't look for search
engines right away; a lot of times the answers that come up on a search
apply to derivatives. Ubuntu is so ubiquitous these days that I've seen
plenty of people that just follow instructions meant for it, but under
Debian.

	So it's (from a certain point of view) comendable that they come to
this list instead. After all this is _the_ Debian User Group; and it's
sad that sometimes they are met with less-than-tolerant responses.

	Although I can completely understand (and to some extent, relate to)
the way some people feel when a discussion list is sometimes treated as
a support desk, a more welcoming response is more likely to create a
more conscientious Debian user.

That was MY €0.02.

Cheers,
Francisco

I must concur. I understand sending people away to research things on 
debian.org. But consider: googling across the internet's trillions of 
documents to find an answer, or filtering through the abundance of 
documentation on debian.org... it's a helluva lot easier to just ask the 
question here. A lot of the people here don't have to look up the 
answer; they know it already. And as demonstrated, the answer isn't that 
difficult to express.

I've been using Debian from probably 20 years now. I'm just advocating 
for some more tolerance.

At least two people have given a *wrong* answer in this thread.

Thank you for all that you wrote.  I will change the sources.list to use
"bullseye" and then run "apt-get update ; apt-get upgrade; apt-get autoremove ;
apt-get dist-upgrade ; apt-get autoremove".  After doing so the system will be
on current Debian testing and it will become Debian stable within a few weeks.
After that the system will remain on Debian stable and not become Debian testing,
correct?

Correct. It will remain on Debian stable for as long as "bullseye" is
the codename of the stable branch (usually something like 2 years).

It's not really an upgrade. It's more a switch in priorities. However to 
answer your question directly, as root do either

     sed -i -s 's/buster/bullseye/g' /etc/apt/sources.list

or

     sed -i -s 's/stable/testing/g' /etc/apt/sources.list

depending on how your source.list file refers to the current stable 
distribution.

After that, do

     apt update
     apt full-upgrade
     apt autoremove

then reboot.

I like this way, it easier and i don't need to open file and change it 
manually.

Yeah, it's wonderfully concise.  Too bad it's wrong.

The format of the security repository lines has changed for bullseye.
You can't just replace buster with bullseye this time around.

In addition, *every* time you do a release upgrade, you need to decide
how to handle third-party repositories.  The typical way you do that is
to disable them temporarily, perform the upgrade, and then re-enable
them -- either exactly as they were before, or with a slightly different
URL pointing to a different version, depending on the repository.

In some cases, you might even be able to get away with leaving the
third-party repository alone and it'll sit there doing nothing during
the release upgrade.  In other cases, it'll interfere, possibly breaking
the upgrade.  We have no way to know other than trial and error.

Another special case is the set of official backports repositories.  You
probably don't want to "just replace buster with bullseye" if you
were using buster-backports.  Most likely you simply want to get rid of
that repository entirely.  If you need bullseye-backports in the future,
after it comes into existence, then you can add it at that time.

Please see the release notes, or the DebianBullseye wiki page, or the
NewInBullseye wiki page.  I've given the URLs already.

Surely you are pulling out legs? You are well aware of the file

  /etc/apt/sources.list ?

Maybe you have something else in mind apart from a ome sentence
throwout?

Hoping to hear from you. But fingers are not crossed.
