#239698 — Trouble upgrading Debian

[Multipart message — attachments visible in raw view] — view raw

Hello,

today, i started to upgrade my computer from Debian 9 (Stretch) to
Debian 11 (Bullseye). I had some trouble finding what i wanted to do, a
completely internet based upgrade, if possible. In the Debian
documention, i did not find this explanation. It says it can be done,
but it does not explain how to do it.

So, i opened the following thread. Do not read it now, there are more
things i will say here, first.

https://www.linuxquestions.org/questions/linux-software-2/upgrading-debian-distribution-4175700202/#post6281677

In the thread, I was advised to not upgrade from Debian 9 to 11 in one
step, because "jumping 2 releases will probably result in MASSIVE
breakage". This should be in the official documentation, no? If there is
this risk, it must be.

So, i should to 2 upgrades: one to Debian 10, and one more to Debian 11.
Fine. And for each one, the steps are:

1. Disable all third party repositories.

2. Edit /etc/apt/sources.list to reflect the next distribution i will
have. Directly, this is just changing all "stretch" occurencies to
"buster"; or all "buster" to "bullseye", in the second upgrade.

3. apt update

4. apt upgrade

5. apt full-upgrade

But after my first edition to sources.list, apt update fails. I have
tried apt-get update to, but it also fails for the apparently same reason.

What should i do to solve this?

You reposted your question two hours later, so I repost the solution and
CC you as well.

1. Start by reading the error message.  If you can't understand it, then
paste it here. As Greg Wooledge already said.

2. Disable colouring e-mails in your Thunderbird. Or disable HTML
e-mails all together, use plain text e-mail.

Yes, it's quite possible that your mail takes a bit longer to

mailing list is open "by design".

I will feel free to ignore your e-mails then, as I do not intend to tire
my eyes reading grey on red, just because you decided to use HTML in
your e-mails and you like these colours. I don't. Good luck with your
enquiry.

Thank you. I did not imagine this would happen. It is the first time, in
my life, that I am upgrading Debian this way.

Mmm... so, I should also 'apt upgrade' with Debian 9 (Stretch)
sources.list? This is different from many directions I found in the web.

I want to upgrade to Debian 10 (as a step to Debian 11), but I am having
trouble with some signature. Let me show a full description. In my first
try, I was not with an updated Debian 9. Someone asked me that, and then
I tried to repeat everything after updating things. So, I

1. Restored sources.list to be what Debian 9 stretch uses

2. Asked 'synaptic' to reload the package database

3. Tried to do 'apt update' as root, but it does not work. GPG signature
error.

As you can see, the plain text version of your email is not very 
readable. I suggest you follow the earlier advice, and set Thunderbird 
to compose your email as plain text, even if only for list mail.

Cheers,
Richard

I think that's what you have to do (add the missing keys to your ring).
I'm unsure of the proper syntax for adding two keys at once. Maybe
wait for David or Greg for confirmation. Good luck.

If it is trivial to me setting my mail manager to use the dark
background i need, and to make it ignore the (usually default)
background of color of all HTML messages, why the people in Debian User
list cannot do it? I will not change my setting! I need it. Learn to
deal with it. Things evolve. Being able to use *bold*, /italic/,
_underscore_ is a minimum of "new" things that help a lot to compose
good messages. If Thunderbird has a problem when writing the automatic
text messages, together with the composed HTML ones, this is a reason to
_**fix**_ it, not to never use anymore. I have installed another mail
manager in my computer: but it is bad, pretty horrible. It does not show
HTML messages. It does not compose HTML messages. And it is pretty
counter intuitive to configure, in several parts. It seems handy, have
nice things. But if you do not know them, or are not familiar enough
with "something", to be able to understand it, you cannot use them. Its
name is Claws Mail. I bet the most important people in this list love
it. So, Thunderbird has some problems (and the HTML thing is not a
problem to me), but it still the best mail manager for me.

This comes across as Rich Text Format, a precursor to Microsoft Word.
These files can be sent with a prefix of .rtf, and it is certainly
supported in LibreOffice Writer.  I am not sure how it works with email
lists, though.

If your mail client is sending both html and plain text most subscribers 
will only see the plain text version (unless they go out of their way to 
look at the html version).

You mean like the markup in the text above? :)

(probably added by Thunderbird for the text version)

While I do agree with you somewhat, as far as I'm aware there is no 
agreed upon standard for HTML mail. How the receiving end will display 
your message is very much open to interpretation.

Some mail clients might even "lie" to you and show e.g. a sans font when 
composing, but the receiving end will display that message with a serif 
font (didn't bother to check the source to see which one of them is 
"wrong").

There should be a setting in Thunderbird to *not* remove "extra" line 
breaks (or similar) for the text version, please enable it.

Last time I tried it Claws Mail could display (but not compose) HTML 
messages, you might need to enable it and/or install some plugin.

Here is reality:

Nobody here is obligated to help you. At all.
If we do, it's out of the goodness of our hearts.
If we don't, it could be:

because we don't know the answer
or
because you are being rude

This is a place where people send questions in plain text and

I agree, we said enough. Good luck to Dedeco Balaco, and goodbye from

Many people will "deal with it" by deleting your messages and moving
on.  Just so you know.

For me, your messages seem OK.  Mutt is presenting me with readable
text.  I don't know what other people are seeing.  However, if you're
intentionally flaunting the guidelines and standards that make mailing
lists work, you can expect a smaller audience for your requests.

Greg, what I saw is Rich Text Format [1], different from html.  I suspect
Mutt (as well as gmail) presents it as it, without issue.  But,
unfortunately, not all email reader software would see it properly.

Hi Dedaco,

I _think_ that the issue of how to upgrade has been covered. 
The release notes cover new features / removed software: the installation
notes cover features of the installation.

https://www.debian.org/releases/bullseye/amd64/release-notes/ has
https://www.debian.org/releases/bullseye/amd64/release-notes/ch-upgrading.en.html#upgrade-to-debian-oldrelease 
and section 4.2 covers this in detail. The instqallation guide is probably 
not so relevant once you have a running Debian system.

Since the release on June 14th or so, this has been extensively covered
in threads here on this list as people have hit problems but I agree, we
could always do more. It has been repeated a few times in different
places that you can't jump a release straightforwardly, so it has to 
be 9 -> 10 -> 11.

Having remade all the steps - do you now have a working system now?
[I'm busy fighting with a system that hasn't been upgraded in a while
and has flaky hardware at the moment: it's often hard to see where
problems are coming from when you are in the middle of them.]

All the very best, as ever,

Andy Cater

https://www.debian.org/releases/buster/amd64/release-notes/ch-upgrading.en.html#system-status

  4.2. Checking APT configuration status

  [...]

  This procedure also assumes your system has been updated to the latest
  point release of stretch. If you have not done this or are unsure,
  follow the instructions in Section A.1, “Upgrading your stretch
  system”.

Admittedly, it's a bit hard to find if you're only skimming, but you
should be reading the full release notes before upgrading.

Well, after the full-upgrade, but this is a good point.  Some of the
services (dbus) require a reboot to restart them.  And of course, you'll
still be on the oldold...stable kernel until you reboot.

Perhaps the forums might suit you better than technical mailing lists.

As one might expect, mutt can handle multipart/alternative in various
ways, according to how you configure it. AFAICT the emails in question
are sensibly constructed, with text/plain and text/html equivalents.

It's already there, as I pointed out and gave the reference for.
In bullseye, it was given even greater prominence by being given
an individual section number.

Ditto.

That is implicit, in that each upgrade is expected to be followed by a
period during which that version is used. Rebooting ensures that any
new kernel is being used.

It's also explicit, in that a system running the previous version's
kernel is not a "pure" system, and unprepared for the next upgrade.

I don't see how that works. Once you've upgraded by one version,
downgrading it again is a non-trivial operation. But I found it
difficult to follow precisely the steps you took.

I have already looked at that. There seem to be links to other forums,
debian.org, release notes for a different upgrade, etc. So my post,
later in the day, didn't add anything except emphasis: follow the
Release Notes in full. (It seemed that the mailing list was late in
being invited to the party.)

The problem with following random posts on the internet for upgrading
is that each one generally addresses a particular aspect where that OP
expressed some difficulty, but doesn't give the end-to-end method.

Cheers,
David.

Curt didn't write that; I did. Please be careful with your attributions.

I'm intrigued to know how this mistake happened, however. Were you 
perhaps replying to a digest message instead of a normal individual one?
