The correct answer is "Si". And then you'll need to do dist-upgrade, too. What error are you seeing?

Did you correct these errors yet?

N: Omitting the file "sources.list.odt" in the directory "/etc/apt/apt.conf.d/", as it has an invalid filename extension
N: Bypassing the file "sources.list.d" in the directory "/etc/apt/apt.conf.d/" because it has an invalid filename extension

I'm gonna take a wild guess and say that you moved sources.list.d into apt.conf.d by accidental click in a root file manager. Root file manager is very dangerous for that exact reason.

Move sources.list.d up one level into /etc/apt/ where it belongs. And if you haven't gotten rid of the mis-named files, get them out of there, too. (You can move them someplace safe if you want to keep them around.) Also, you might do well to edit system files with a plain text editor instead of libreoffice or whatever word processor you used.

Edit: almost forgot to say this: It looks like you're finished upgrading to ascii. I have no idea what happened with the dbus-user-session error.

Edit2: Make sure you don't have anything weird in sources.list.d, such as mis-named files or files that contain jessie sources. In fact, if there are any sources in there, comment them all out. The ones you have in sources.list are correct.

If you use the debian/devuan installer, you will install from the repository if you do a netinstall or from the media if you used a DVD image instead of a netinstall and you don't choose a mirror. If you use refractainstaller, you will install the live iso. If the live iso has grub-efi-amd64 installed, it will be bootable on uefi.

If the live iso does not have grub-efi-amd64 installed, you should install that package in the live system before you run the installer. When it asks where you want the bootloader, don't choose a location. The installer will handle adding the bootloader (or let you do it manually if you like working in a chroot terminal.) Another option is to include grub packages in your iso and install whichever ones are needed when you install to hard disk. Oh yeah, if you hack the live iso into an installer iso, I think the grub packages are already there in /pool.

I don't think you need to reinstall yet. Just stop using synaptic temporarily and you won't see that error.

Try

apt-get update && apt-get upgrade

and lets see if we can get you back to it failing because of dbus.

That will work until synaptic is upgraded to a newer version. Then your edited .desktop file will be replaced. I solved that problem by making a separate .desktop file called synaptic-gksu.desktop. Make sure to change the Name field, because you will have two entries in your menu for synaptic. You need to be able to tell them apart.

SR, nope. It's a file, not a line.

Use a valid filename extension. (i.e. ".list" not ".lists").  Are you sure you're up for this?

You should not need the 'packages' repo. When I did the upgrade, I used only one line in sources.list:

deb http://us.mirror.devuan.org/merged ascii main

The problem with the upgrade is not in the sources, it's in the packages. To quote myself from above:

I sure hope this isn't your main system that you're trying to upgrade. Maybe you should practice in a VM or on a spare computer. Then you'll know what to expect.

I don't know what the best course of action is at this point. If you can figure out what's trying to pull in dbus-user-session, you might be able to avoid it. Or, you could install equivs and make a fake dbus-user-session like I did. Somehow, I was able to remove it afterward.

Any of the installer images and the minimal live will give you a minimal system. Only the desktop-live forces you to take the whole desktop. Uncheck everything (or everything except 'standard system utilities' and the tasksel window.

As I said above, replace rsyslog first.

Or maybe wait a few weeks.

gconf2.  Maybe you were thinking x because there's a problem with xserver, too. It won't run without a display manager. Oh, and speaking of that, there's a problem with the display manager. But you'll never know that until you get past the problem with rsyslog.

To OP and all the others who are itching to try ascii...

It's only been three weeks since devuan jessie went stable. Three weeks is not enough time to prepare the next release.

I think two of those three weeks were spent in recovery. Things are happnening now. The major blockers should be fixed soon. Meanwhile, a careful debootstrap install will work and so will a prepared upgrade (e.g. replace rsyslog first). Be prepared for breakage and know how to handle it.

The answer to this is, "Something must be wrong."

More information about what did not work and what error messages you got will result in a better answer to your specific problem.

I think once again, that you can blame the debian developers for that. Devuan devs have been focused on removing systemd dependencies, not on changing everything else.

Yes, and that use case is exactly the reason the CD is offered.

You're going to have to use your network one way or the other. If you install CD1, you'll need to add packages from the network (like libreoffice for instance.) Your alternative is to download the DVD and probably have everything you want locally.

Edit: Here's another option - you can buy a devuan dvd:

Edit2: I just checked a debian-8.3-CD-1. It does have libreoffice. That's new for jessie. In wheezy and squeeze it was on CD-2. I don't know why there's a difference, and it doesn't change your options, anyway.

I don't know enough about how the installer isos are made to answer your first question. I know the choices in tasksel are hard-coded in the source code. I don't know if tasksel adapts itself if any of those choices are not on the media, but I think it does not.

A debian install from CD-1 does not give you a full set of applications if you don't use a network mirror. Been there, done that.

The jessie-vdev iso was made for testing vdev, not to provide someone with a full system. I tried to keep it light so the download would be smaller.
