go back to stable

[kmchen]

Hi,

I have actually a Debian Strech / Sid installed and would like to go to a stable Buster. Here is my conf:

Can I do that safely or do I have to do a complete reinstall ?

Any help apreciated

While I imagine this might be possible I cannot think of a reason why you would attempt it, considering a full installation can be done easily I would say it would yield a better quicker cleaner result.

[Hallvor]

As an experiment, go for it. I would run tasksel and remove the desktop environment and anything but the core system, and then use apt pinning to attempt a downgrade.

If you want a sensible suggestion, just do a clean install.

You can go from stable --> testing --> unstable. But the reverse direction is not "possible". Actually, if you are an expert and if you are willing to spend some time and if you are real careful and if you know what you are doing, then it might be possible to go from unstable to testing and then to stable. The installer scripts are not designed to do that. So in the process, your configuration files might be lost and...

Thanks for your messages. I had not receive mail notifications - don't know why, my email is correct - and did not know there had answers.

I finaly unpined Sid and did a normal dist upgrade with success:

$ apt dist-upgrade


Upgrade executed succesfully but I had to reinstall KDE, what I did without problems, and now mysql disappeared too and I can't re-install it.
Following https://linuxize.com/post/how-to-instal ... debian-10/, that I executed as root in spite of sudoer, that install broke and now here is the situation:

You cannot go back to stable (current stable is buster, not stretch) by changing the repositories. They don't go back to earlier versions that way.
The best and fastest way to go back to stable from Sid is to reinstall.

[kmchen]

so I did a reinstall and now not only mysql has to be reinstalled:
mysql
php-fpm
apache
amarok
special usb sound card drivers
...

and all /etc.. 15years of cutomisations

Many of these were workin after upgrade (apache, sounds,.. did not test all but a lot of saved work)
If someone come on that post, do really think about reinstalling a system instead of upgrading...
