#157822 — Upgrading Debian

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

I just want to make sure again. How can one upgrade from one version of
Debian to other without losing data or without formatiing the partition,
simply as Ubuntu does.
An earlier mail in this mailing list stated to reboot from iso image and
install in the same old traditional way.
This Facebook post states something else, and I couldn't make sure what to
do without bricking up my hard configured system.

What

I usually do is to update /etc/apt/sources to the version I want
to upgrade to. Then I log out from X and log on to the console.

# apt-get update
# apt-get upgrade
# apt-get dist-upgrade

Then reboot.

This has only failed when I have tried to upgrade to broken "testing"
versions.

As always, make a backup before you start :)

Same (almost) for me:

$ sudo apt-get update && sudo apt-get upgrade

$ sudo apt-get dist-upgrade


(I don't remember if I even needed to reboot)

I stayed with stable and I never experienced failure

Reboot is recommended whenever your kernel or some very basic library
is upgraded (otherwise the machine keeps running the old binary).

Plus it makes sense, just because if your machine becomes unbootable after
the upgrade, you'd notice right away and not weeks after, when you don't
expect it.

So I'd say: you don't need to reboot right away, but schedule a reboot
at some convenient time "soonish".

I think 'edit /etc/apt/sources' is a less ambiguous. I would add that
before editing /etc/apt/sources, I would make sure the current version
is up to date first.

Same here.  Always fully upgrade what you have already, before attempting to 
upgrade to a new version.  Then edit your sources.list, re-consult the 
release notes, and upgrade following the instructions.

But in this particular case he doesn't want to upgrade in that sense.  He just 
needs to update his system, which because of the timing will go from 8.1 to 
8.2.  So he doesn't need to do anything special.  I have met Ubuntu users 
having problems with point releases before.  I don't know why.

I think you're looking for this :

We don't know Ubuntu.  Don't expect us to give you instructions in terms of 
Ubuntu.

You are being very unclear what you want to do.  From 8.1 to 8.2 is a normal 
routine upgrade.  It is not a version change.  Earlier you said that you 
wanted to go from 6 to 8.  That is totally different.  

And are you trying to do this without access to the internet??  

You seem to be trying to do several different things.  Which do you want to 
do?

> An earlier mail in this mailing list stated to reboot from iso image and
> install in the same old traditional way.

For a version upgrade (and 8.1 to 8.2 is not a version upgrade) many people 
prefer to do this.  Many have successfully upgraded through many versions 
without reinstalling.

If you can't be clear what you are trying to do you are certainly likely to 
brick your system one way or another.

But whatever you do, keep good backups.  Then it won't matter if you do brick 
your system.

So, to summarise:
What *exactly* are you trying to do?
What are you trying do it to?  (Machine specs, what have you now etc.)
What facilities have you got?

And there is no rule book.  This is Debian not Ubuntu.  You may - indeed will, 
if you get any at all - get different advice.  We don't all agree with each 
other. ;-)

I always found it best to follow Debian's instructions in the Release
Notes and/or Installation Instructions of the version you want to
upgrade to. AND back up your data before doing anything..

Many times, there's more involved than just simply apt-get update,
apt-get upgrade, etc.

He doesn't want to upgrade from one version to another.  He just wants to do a 
normal upgrade in Jessie, that because of where we are now, and when he last 
upgraded, will take it from 8.1 to 8.2.

Oh.  But that's what he said.  Others seemed to misunderstand, too.  In
any case, if he had read the instructions . . .

What is it with people and instructions?

I know.  It took me a while to work out what he actually wanted with all the 
drama. ;-)  People who come from Ubuntu don't understand about point 
releases.  Since I don't know Ubuntu, I don't know what it is that they are 
thinking of.

Different terminology.  With most distros "update" means what
"upgrade" does with Debian.  And "upgrade" means "dist-upgrade."

Yes, Ubuntu is a different beast.   The only experience I have with
it is from its debut release years ago. Hated it so much, I uninstalled
it a week later and never tried it again.  I don't know why people love
it so much.  To each, his own, I guess.

I do run Ubuntu LTS on a machine at my work place and I don't know what 
the thinking is
either. :-\

If there is an actual new release the update manager tells you about it 
and gives you the
option to upgrade, no mucking about with sources.list files, ISOs, etc...
After the upgrade you then have to go through any *.list files in 
'/etc/apt/sources.list.d/'
if you have any to re-enable them and make sure they point where they 
need do.
Not sure what happens if you have unofficial stuff in your sources.list 
instead of in placing
them in their own *.list files.

Personally I prefer editing my *.list files and pulling in smaller 
batches of updates.

For point releases, if you keep up with the updates you probably have 
most of it by the
time install images are made available anyway so just keep doing updates 
the same way
no reason to re-install.

There is a possibility of some driver/init related stuff being a little 
different in a re-install
compared to just doing the normal update, but the odds of noticing the 
difference is pretty
small so.... If it ain't broke, don't fix it.

In the general sense, more or less the same as it is with Debian.:-)

The more times you ask, the more different answers you will receive.
At some point you have to dive in and do it, just as you yourself
have encouraged others to do (probably unwisely in that case):

I'm not sure what you mean by "old traditional way", particularly as
you have muddied the waters by bringing up Ubuntu. But, at face value,
that doesn't sound like an upgrade but more like a reinstallation.
Not knowing which thread you were referring to, I can't comment further.

> This Facebook post states something else, and I couldn't make sure what to do
> without bricking up my hard configured system.

I'm not sure what you mean by "bricking". If you follow the
instructions on the Debian website, you won't go far wrong.
If/when you do, you'll learn something, and by all means post specific
questions here if you need help.

> https://www.facebook.com/groups/lifewithdebian/permalink/10153149941663977/

Sorry, but I've no idea what I'm meant to see at that address.

The upshot is to try doing it, rather than asking for people here to
post what's already amply documented on Debian.

Cheers,
David.
