Re: Crossgrading Wheezy from 32bit to 64bit: Solving package dependency problems after kernel change.

[Pieter Van Isacker]

Hi Sven,

Thanks for that suggestion.
I've quickly tried this on a test VM and indeed crossgrading seems to work much 
better in debian 9 compared to debian 7.

Thanks,
Pieter

About two years ago, before upgrading from wheezy to jessie, I
successfully switched my system from 32 to 64 bit (after two failed
trials :)
When I had first started with the tips from the above link, the results
were desastrous :)
The advice from the following page:
http://blog.zugschlus.de/archives/972-How-to-amd64-an-i386-Debian-installation-with-multiarch.html
worked for me, although of course I cannot guarantee that they will work
for you either. And I'll have to add that I began to do as above page
instructed me only halfway into the process (when I had almost manoeuvered
myself into disaster again), so I cannot tell about the first half of that
page's instructions; the second half though surely saved my day back then.

Good luck (and don't forget to backup first!! :)

Michael

+1

copy data (backup)
dpkg --get-selections
install 64
dpkg --set-selections
migrate configurations

You are better off first upgrading to Debian 9 and *then* trying to
crossgrade. The packages in Debian 9 are more prepared for multi-arch
than the one in Debian 7.

Still, there is no guarantee it will work and for production systems I
strongly advise you to just backup the data and reinstall from scratch
as 64bit system.

Sven.

Crossgrading Wheezy from 32bit to 64bit: Solving package dependency problems after kernel change.

[Pieter Van Isacker]

Hi all,

While testing change a Debian Wheezy from 32bit to 64bit I ran into an issue. 
Following the guide on https://wiki.debian.org/CrossGrading 

Once we've change to 64bit we plan to update to Debian 8 and then possibly to 
Debian 9

Changing the kernel to 64bit works fine, installing a 64bit version of dpkg, 
tar & apt also works fine.

But then when having to change the installed packages from 32bit to 64bit I ran 
into trouble.
When trying to run install vim for example:

# apt-get install vim

Building dependency tree
Reading state information... Done
