Crossgrading a complex Desktop and Debian Developer machine running Debian 9, for real.

After sometime without looking into this problem, I decided to do another try. I do not found a way to do a complex crossgrade of my desktop without massively removing packages. And there are bug and bug that require to edit the config scripts of the packages.

So here is my another try to do a crossgrade of my desktop, this time for real.

apt-get update
apt-get upgrade
apt-get autoremove
apt-get clean
dpkg --list > original.dpkg
apt-get --download-only install dpkg:amd64 tar:amd64 apt:amd64 bash:amd64 dash:amd64 init:amd64 mawk:amd64
for pack32 in $(grep i386 original.dpkg | egrep "^ii " | awk '{print $2}' ) ; do 
  echo $pack32 ; 
  apt-get --download-only install -y --allow-remove-essential ${pack32%:i386}:amd64 ; 
done
cd /var/cache/apt/archives/
dpkg --install libacl1_*amd64.deb libattr1_*_amd64.deb libapt-pkg5.0_*amd64.deb libbz2-1.0_*amd64.deb dpkg_*amd64.deb tar_*amd64.deb apt_*amd64.deb bash_*amd64.deb dash_*amd64.deb 
dpkg --install --skip-same-version *.deb
dpkg --configure --pending
dpkg --install --skip-same-version *.deb
dpkg --remove libcurl4-openssl-dev:i386
dpkg --configure --pending
dpkg --remove libkdesu5 kde-runtime
apt-get --fix-broken install
apt-get install  $(egrep "^ii"  ~/original.dpkg | grep -v ":i386" | grep -v "all" | grep -v "aiccu" | grep -v "acroread" | grep -v "flashplayer-mozilla" | grep -v "flash-player-properties" | awk '{print $2}')

Reboot.

Then the system failed to boot, missing lvm2 package.

Boot with a live CD.

sudo -i
mount /dev/sdc2         /mnt
mount /dev/vg100/usr /mnt/usr
mount /dev/vg100/var /mnt/var
mount -o bind /proc    /mnt/proc
mount -o bind /sys     /mnt/sys
mount -o bind /dev/    /mnt/dev
mount -o bind /dev/pts  /mnt/dev/pts
chroot /mnt /bin/su -
apt-get install lvm2
exit
reboot

Still somethings do not work, like command fakeroot.

for pack32 in $(grep i386 original.dpkg  | egrep "^ii " | awk '{print $2}' ) ; do     
  echo $pack32 ;     
  if dpkg --status $pack32 | grep -q "Multi-Arch: same" ; then       
    apt-get -y install ${pack32%:i386}:amd64 ;     
  fi ;   
done

for pack32 in $(grep i386 original.dpkg  | egrep "^ii " | awk '{print $2}' ) ; do     
  echo $pack32 ;     
  apt-get -y install ${pack32%:i386}:amd64 ;     
done

Now is time to find what still does not work and how to solve it.

Crossgrading a complex Desktop and Debian Developer machine running Debian 9

This article is an experiment in progress, please recheck, while I am updating with the new information.

I have a very old installation of Debian, possibly since v2, dot not remember, that I have upgraded since then both in software and hardware. Now the hardware is 64bits, runs a kernel of 64bits but the run-time is still 32bits. For 99% of tasks this is very good. Now that I have made many simulations I may have found a solution to do a crossgrade of my desktop. I write here the tentative procedure and I will update with more ideias on the problems that I may found.

First you need to install a 64bits kernel and boot with it. See my previous post on how to do it.

Second you need to do a bootstrap of crossgrading and the instalation of all the libs as amd64:

 apt-get update
 apt-get upgrade
 apt-get clean
 dpkg --list > original.dpkg
 apt-get --download-only install dpkg:amd64 tar:amd64 apt:amd64 bash:amd64 dash:amd64 init:amd64 mawk:amd64
 cd /var/cache/apt/archives/
 dpkg --install dpkg_*amd64.deb tar_*amd64.deb apt_*amd64.deb bash_*amd64.deb dash_*amd64.deb *.deb
 dpkg --configure --pending
 dpkg -i --skip-same-version dpkg_*_amd64.deb apt_*_amd64.deb bash_*_amd64.deb dash_*_amd64.deb mawk_*_amd64.deb *.deb
 
 for pack32 in $(grep i386 original.dpkg  | egrep "^ii " | awk '{print $2}' ) ; do 
   echo $pack32 ; 
   if dpkg --status $pack32 | grep -q "Multi-Arch: same" ; then 
     apt-get --download-only install -y --allow-remove-essential ${pack32%:i386}:amd64 ; 
   fi ; 
 done

 dpkg --install /var/cache/apt/archives/*_amd64.deb
 dpkg --install /var/cache/apt/archives/*_amd64.deb
 dpkg --print-architecture
 dpkg --print-foreign-architectures

But this procedure does not prevent the "apt-get install" to have broken dependencies.

So trying to install the core packages and the libraries using "dpkg -i".

apt-get update
apt-get upgrade
apt-get autoremove
apt-get clean
dpkg --list > original.dpkg
apt-get --download-only install dpkg:amd64 tar:amd64 apt:amd64 bash:amd64 dash:amd64 init:amd64 mawk:amd64
for pack32 in $(grep i386 original.dpkg | egrep "^ii " | awk '{print $2}' ) ; do 
  echo $pack32 ; 
  if dpkg --status $pack32 | grep -q "Multi-Arch: same" ; then 
    apt-get --download-only install -y --allow-remove-essential ${pack32%:i386}:amd64 ; 
  fi ; 
done
cd /var/cache/apt/archives/
dpkg --install dpkg_*amd64.deb tar_*amd64.deb apt_*amd64.deb bash_*amd64.deb dash_*amd64.deb *.deb
dpkg --configure --pending
dpkg --install --skip-same-version dpkg_*_amd64.deb apt_*_amd64.deb bash_*_amd64.deb dash_*_amd64.deb mawk_*_amd64.deb *.deb

dpkg --remove libcurl4-openssl-dev
dpkg -i libcurl4-openssl-dev_*_amd64.deb

Remove packages until all there is no brokens packages

dpkg --print-architecture
dpkg --print-foreign-architectures
apt-get --fix-broken --allow-remove-essential install

Still broken, because apt-get removed dpkg

So instead of only installing the libs with dpkg -i, I am going to try to install all the packages with dpkg -i:

apt-get update
apt-get upgrade
apt-get autoremove
apt-get clean
dpkg --list > original.dpkg
apt-get --download-only install dpkg:amd64 tar:amd64 apt:amd64 bash:amd64 dash:amd64 init:amd64 mawk:amd64
for pack32 in $(grep i386 original.dpkg | egrep "^ii " | awk '{print $2}' ) ; do 
  echo $pack32 ; 
  apt-get --download-only install -y --allow-remove-essential ${pack32%:i386}:amd64 ; 
done
cd /var/cache/apt/archives/
dpkg --install dpkg_*amd64.deb tar_*amd64.deb apt_*amd64.deb bash_*amd64.deb dash_*amd64.deb *.deb
dpkg --configure --pending
dpkg --install --skip-same-version dpkg_*_amd64.deb apt_*_amd64.deb bash_*_amd64.deb dash_*_amd64.deb mawk_*_amd64.deb *.deb
dpkg --configure --pending

Remove packages and reinstall selected packages until you fix all off them. Follow the trial for my machine:

dpkg --remove rkhunter
dpkg --remove libmarco-private1:i386 marco mate-control-center mate-desktop-environment-core mate-desktop-environment-core  mate-desktop-environment mate-desktop-environment-core mate-desktop-environment-extras
dpkg --remove libmate-menu2:i386 libmate-window-settings1:i386 mate-panel mate-screensaver python-mate-menu libmate-slab0:i386 mozo mate-menus
dpkg --remove libmate-menu2:i386 mate-panel python-mate-menu mate-applets mate-menus
dpkg -i libmate-menu2_1.16.0-2_amd64.deb
dpkg --remove  gir1.2-ibus-1.0:i386 gnome-shell gnome-shell-extensions gdm3 gnome-session
dpkg --remove  gir1.2-ibus-1.0:i386
dpkg --remove libmateweather1:i386
dpkg -i libmateweather1_1.16.1-2_amd64.deb

apt-get --fix-broken --download-only install
dpkg --skip-same-version --install dpkg_*amd64.deb tar_*amd64.deb apt_*amd64.deb bash_*amd64.deb dash_*amd64.deb *.deb
dpkg --configure --pending
dpkg -i python_2.7.13-2_amd64.deb
dpkg --configure --pending
dpkg -i perl_5.24.1-3+deb9u1_amd64.deb perl-base_5.24.1-3+deb9u1_amd64.deb
dpkg -i exim4-daemon-light_4.89-2+deb9u1_amd64.deb exim4-base_4.89-2+deb9u1_amd64.deb
dpkg -i libuuid-perl_0.27-1_amd64.deb
dpkg --configure --pending
dpkg --install gstreamer1.0-plugins-bad_1.10.4-1_amd64.deb libmpeg2encpp-2.1-0_1%3a2.1.0+debian-5_amd64.deb libmplex2-2.1-0_1%3a2.1.0+debian-5_amd64.deb
dpkg --configure --pending
dpkg --audit

Now fixing broken dependencies on apt-get. Found no other way than removing all the broken packages.

dpkg --remove $(apt-get --fix-broken install | cut -f 2 -d ' ' )
apt-get install $(grep -v ":i386" ~/original.dpkg | egrep "^ii" | grep -v "aiccu" | grep -v "acroread" | grep -v "flash-player-properties" | grep -v "flashplayer-mozilla" | egrep -v "tp-flash-marillat" | awk '{print $2}')

Crossgrading a more typical server in Debian9

First you need to install a 64bits kernel and boot with it. See my previous post on how to do it.

Second you need to do a bootstrap of crossgrading:

 apt-get clean
 apt-get upgrade
 apt-get --download-only install dpkg:amd64 tar:amd64 apt:amd64 bash:amd64 dash:amd64 init:amd64 mawk:amd64
 dpkg --install /var/cache/apt/archives/*_amd64.deb
 dpkg --install /var/cache/apt/archives/*_amd64.deb
 dpkg --print-architecture
 dpkg --print-foreign-architectures

Third, do a crossgrade of the libraries:

 dpkg --list > original.dpkg
 apt-get --fix-broken --allow-remove-essential install
 for pack32 in $(grep :i386 original.dpkg | awk '{print $2}' ) ; do 
   if dpkg --status $pack32 | grep -q "Multi-Arch: same" ; then 
     apt-get install --yes --allow-remove-essential ${pack32%:i386} ; 
   fi ; 
 done

Forth, do a full crossgrade:

 if ! apt-get install --allow-remove-essential $(grep :i386 original.dpkg | awk '{print $2}' | sed -e s/:i386//) ; then
   apt-get --fix-broken --allow-remove-essential install
   apt-get install --allow-remove-essential $(grep :i386 original.dpkg | awk '{print $2}' | sed -e s/:i386//)
 fi

Crossgrading a minimal install of Debian 9

By testing the previous instructions for a full crosgrade I run into trouble. Here is the results of my tests to do a full crossgrade of a minimal installation of Debian inside a VM.

First you need to install a 64bits kernel and boot with it. See my previous post on how to do it.

Second you need to do a bootstrap of crossgrading:

 apt-get clean
 apt-get upgrade
 apt-get --download-only install dpkg:amd64 tar:amd64 apt:amd64 bash:amd64 dash:amd64 init:amd64
 dpkg --install /var/cache/apt/archives/*_amd64.deb
 dpkg --install /var/cache/apt/archives/*_amd64.deb
 dpkg --print-architecture
 dpkg --print-foreign-architectures
 apt-get --fix-broken --allow-remove-essential install

Third do a full crossgrade:

 apt-get install --allow-remove-essential $(dpkg --list | grep :i386 | awk '{print $2}' | sed -e s/:i386// )

This procedure seams to be a little fragile, but worked most of the time for me.

Crossgrading the kernel in Debian 9

I have a very old installation of 32bits Debian running in new hardware. Until now running a 64bits kernel was enough to use efficiently more than 4GiB of RAM. The only problem I found was the proprietary drivers from AMD/ATI and NVIDIA, that did not like this mixed environment and some problems with openafs, easilly solved with the help of the package maintainers of openafs. Crossgrading the Qemu/KVM to 64 bits did not pose a problem, so I have been running 64bits VMs for some time.

But now the nouveau driver do not work with my new display adapter and I need to run tools from OpsCode not available as 32bits. So is time to do a CrossGrade. Finding some problems I can not recommend it to the inexperienced people. Is time investigate the issues and report bugreports to Debian were appropriate.

If you run 32bits Debian installation you can easily install a 64bits kernel . The procedure is simple and well tested.

dpkg --add-architecture amd64
apt-get update
apt-get install linux-image-amd64:amd64

And reboot to test the new kernel.

You can expect here more articles about crossgrading.

Preview of xorp v1.8.3 in Debian

I attended DebConf11 and my main objective was to package xorp v1.8.3 for Debian. In the spirit of release early and release often here are the links for a package compiled for Debian v6.0 aka squeeze. The work is not finished and most important was not yet reviewed by a Debian Developer. Reports of success are important.

For downloading:

xorp_1.8.3-1_wip4_bpo60_1_i386.deb

xorp_1.8.3-1_wip4_bpo60_1_amd64.deb

For accessing the sources or using apt-get add the following lines to your /etc/apt/sources.list:

deb http://debian.tagus.ist.utl.pt/debian squeeze/UNRELEASED main contrib
deb-src  http://debian.tagus.ist.utl.pt/debian squeeze/UNRELEASED main contrib
