Migrating from Buster to Beowulf - feedback needed

pcalvert · 2020-05-23 09:44:51

I migrated a new Debian Buster system to Beowulf, and things went well (for the most part). There is a problem, though. After the desktop appears, there is constant, non-stop disk activity. Running top shows a couple of CPU hogs:

udevd      20 to 30 % CPU
udisksd    14 to 20% CPU
udevd      1 to 2 % CPU

Based on a hunch, I uninstalled gvfs and the problem went away.

Having trouble with a Debian Buster VPS migrating to Beowulf. Dependency issues when trying to install eudev. See below. (some sections omitted for brevity). To be clear, I am following the docs from devuan.org (https://www.devuan.org/os/documentation/dev1fanboy/en/buster-to-beowulf ). Not the earlier instructions in this thread.

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:

 dconf-gsettings-backend : Depends: dconf-service (>= 0.30.1-2) but it is not going to be installed
                           Depends: dconf-service (< 0.30.1-2.1~) but it is not going to be installed

From the link you posted above:

Once this is done eudev needs to be installed. Note that if you’re using Gnome it will be removed by this command, but can be installed again after migration.
root@debian:~# apt-get install eudev
The last command is known to cause package breaks but we will fix this as part of the migration process.
root@debian:~# apt-get -f install

Did you run "apt -f install"? Or "apt-get -f install"?

Sorry, I wasn't clear. I did. See below:

Reboot I think would be unwise as it didn't install eudev. Trying to install eudev again results in the same error. The only hint is that it's holding packages, and also on a VPS (yet kvm).

IIRC, you may reboot and continue the migration with:

apt-get dist-upgrade

No dice. Reboot works, but apt-get dist-upgrade results in being prompted to remove the running kernel. I don't agree to that, and then it breaks down.

I'm afraid I need to find a different VPS vendor. One that supports custom ISOs. For what it's worth, I migrated an identical Jessie or Stretch (forget now) Debian to Devuan some years ago with this vendor. Back then, the only trick was adding /etc/inittab. Now with Buster it's resulting in below.

Did you try installing sysvinit-core before attempting to install eudev?

little · 2021-01-08 03:48:10

So I bashed through a number of commands. I installed sysvinit-core, yes. I ended up removing the kernel, and then reinstalling it. Quite a mess, but I was able to get it to complete the install. At one point, it reboot with no eth0 iface, so the emergency console was used, and then after installing eudev and rebooting, everything looked right. I'll try to update this post with some steps for future reference. It was not straightforward, but it was possible. I suspect because this was a VPS.

Maybe I would've had better luck if I followed the instructions in this thread I had followed before for the RPI. Anyways, alls well that ends well.
