Re: [DNG] [devuan-dev] Migrating from Buster to Beowulf - feedback needed

[José Marinho via Dng]

For the first point, you are right, the final hyphen makes a big difference and 
now I am free of the dbus delay and can reach a GUI through Lightdm. But the 
other issue persists:
root@dserver:~# apt install --purge policykit-1

Building dependency tree   
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 policykit-1 : Depends: libpolkit-agent-1-0 (= 0.105-25+devuan4) but 0.105-25 
is to be installed
   Depends: libpolkit-backend-1-0 (= 0.105-25+devuan4)
   Depends: libpolkit-gobject-1-0 (= 0.105-25+devuan4)
E: Unable to correct problems, you have held broken packages.

I'm going to post you the output of some commands with the hope it may help you 
to understand:

root@dserver:~# cat /etc/apt/preferences
cat: /etc/apt/preferences: No such file or directory
root@dserver:~# ls -l /etc/apt/preferences.d/
total 0

Like I mentioned on my previous post, the system I'm using for this tests is a 
Virtualbox VM with Debian server installed with a netinstall image and after 
that I install the metapackage task-xfce-desktop, but I did not change any 
preference from the stock that comes from Debian

Finally, I managed to get to Beowulf from Buster by doing what is indicated in 
the text file I send as an attachment.

Hope it would be helpful.

Hi all,

From a brand new debian server installation on Virtualbox I install desktop 
stuff by installing task-xfce-destop metapackage and try your instructions. I 
don't know if I miss or misunderstand something. What I got was this:

After installing devuan-keyring, changing apt sources, updating apt sources, 
editing /var/lib/dpkg/status file for removing systemd-sysv of the end of the 
line, do an "apt install --purge sysvinit-core dbus dbus-x11 libnss-systemd" 
and rebooting the system, when I rebooted I notice that
when the system start after the reboot, it gets stuck on dbus and avahi-daemon 
delaying init much more than usual. Besides this, it delays too a lot when I 
try to log in the system by console or ssh. When I finally reach a root console 
and issue : "apt install --purge policykit-1" I get this 
output:

apt install --purge policykit-1
Reading package lists... Done
Building dependency tree   
Reading state information... Done
Some packages could not be installed. This may mean that you have

I hope this will help

Yes, thanks. On a quick look all of your difficulties look related to tasksel. I
think the basic process I posted is OK.

I think this is a problem in devuan's task-xfce-desktop.

We are quite behind debian (buster has 3.53, beowulf has 3.48+devuan1.1) and
devuan's version also has a (now) unhelpful dependency on
libpolkit-backend-consolekit-1-0.

Could you try removing task-xfce-desktop first?

Thanks.

Could you check that line. It may just be a typo, but should be

 apt install --purge sysvinit-core dbus dbus-x11 libnss-systemd-

with a hyphen at the end. That cured the dbus delays for me.

This is odd as 0.105-25 is the buster version.

I had tested this from xfce4 install but not the task-xfce4-desktop
metapackage. I will try and see if I can reproduce.

Are there any  held packages or apt pinning in force?

Yes I wondered about that. What would work is a libpam-systemd.deb with Debian
#935304 fixed. But it would be a pain to maintain as we would have to keep the 
versions in
step with the rest of the systemd in buster. We also couldn't have it in the
main devuan archive as we use libpam-elogind to provide libpam-systemd, so it
would have to be a download and manual install.

In the end, I feel it is more appropriate to fix Debian bugs in Debian if we 
can.

Done!

The transitional systemd-sysv package I talked about a few days ago to smooth
over #935304 isn't going to work as I had forgotten that sysvinit-core conflicts
with systemd-sysv.

The hack to work around #935304 by editing /var/lib/dpkg/status is not pretty at
all. If you don't want it you will have to accept removal of some GUI components
with libpam-systemd and then reinstall them after libpam-elogind is in place.

I hope the instructions are reasonably clear.

Do give feedback.

Thanks

Mark


Would a transitional package that makes the edit to /var/lib/dpkg/status 
be a sane solution?

Kinda, sorta.

I think it's consistent with my experience of migrating buster to beowulf. 
At the time, I was ready to say that it can't be done and we shouldn't 
support it, but I did succeed after two days of messing with it. Nice to 
see you have a way to make it work smoothly.

I think that is all covered and works fine once the install process is
done. However, see below:

I think it is (if you want to avoid removing and then reinstalling many desktop
packages). There is a dependency loop here we have to break.

libpam-systemd depends systemd-sysv. libpam-systemd also depends
systemd. Devuan's libpam-elogind provides libpam-systemd but conflicts with
systemd which must be removed first.

However, to get systemd uninstalled we first have to replace systemd-sysv with
sysvinit-core (leaving systemd installed) and reboot. systemd and elogind
conflict so we cannot use libpam-elogind to replace libpam-systemd *yet*.

This is the point we need a transitional package to temporarily satisfy
libpam-systemd's systemd-sysv dependency whilst the system is rebooted.

After reboot, systemd is no longer PID1 so can be removed and we can then
complete the transition replacing libpam-systemd with libpam-elogind, removing
systemd and installing elogind.

I hope that is clearer.

Should you also be installing the devuan-baseconf package? Or does that get 
pulled in automatically during the transition?

But it should use libpam-elogind.  Perhaps we need to ban libpam-systemd
to force the use of libpam-elogind instead.  The only thing is we need
to check if their is a dep version check on libpam-systemd in which case
we'd also need to set the version for the "Provides: libpam-systemd" also.

Lets see if their is a response.  If there is nothing in a week I may
prod the DPL again.  He was very impressed with your professionalism in
the case of justifying the elogind bug.

I don't think a transitional package is required.
