It looks too tricky. I thought you installed Cinnamon Desktop only
recently, played with it for few hours and now decided to uninstall.
With hundreds of upgrades, packages obsoleted and replaced, possibly
with many installs/removals during the lifetime of the system it
may not be worth the effort to try to uninstall Cinnamon as a group.
Simply it may be easier to install a new system from scratch.

If you want to continue your efforts my suggestion is to try to
figure out how the dependency chain looks like (which packages make
systemd and dnf require Cinnamon) find the best place to break it
and remove some packages forcefully with "rpm -e --nodeps", then
try to dnf group remove "Cinnamon Desktop" (hopefully will work
because you have forcefully broken the dependency chain), then
as soon as you uninstall Cinnamon make sure you install any other
desktop, like GNOME or whatever you prefer. It should pull all
requirements including those you have forcefully removed.
Your system will become unstable during that process, your graphics
subsystem may crash and may be unable to boot so better work
on a text console and better do not reboot until you will have
finished.

I'm not sure it will work, I never tried this. I tried performing
similar crazy tasks and usually it took several days sometimes
with success and sometimes without, always with a conclusion it
would be better to install a new system from scratch.

Again, think if it's worth the effort.

Best regards,

Rafal

Try `dnf group remove cinnamon-desktop` or Cinnamon -- "Cinnamon Desktop"
may be trying to remove the environment group cinnamon-desktop-environment
which includes the whole base system.

This appears to have no effect on dnf group operations?

```
[root@ragnia ~]# dnf --setopt "clean_requirements_on_remove=False" group remove 
"Cinnamon Desktop"
Last metadata expiration check: 2:25:11 ago on Wed May 10 10:42:51 2017.
Dependencies resolved.
Error: The operation would result in removing the following protected packages: 
dnf, systemd-udev, systemd.
```

I tried editing /etc/dnf/dnf.conf as well with the same results

I have not, but since it's not my main workstation I can live with that
for now

Hrm, I haven't looked at dnf history, fwiw this is the rough timeline of
events:

1. install fedora 23 workstation (comes with gnome)
2. dnf group install "Cinnamon Desktop"
3. live with it for a year or so
4. fedora-upgrade to fedora 24, then to 25
5. found the alleged bug

As you can see, the "original" DE was gnome, unsure how Cinnamon
packages are taking over dependencies, I am going to test Dan's approach
and not uninstall dependencies (only components of the group)

1. Have you fixed your problem already?
2. I guess that dnf history undo would do the job.
3. What is your Fedora version (or what is your distro if it is
not Fedora) and what desktop environment did you have installed
before installing Cinnamon Desktop? My guess is that Cinnamon
replaced (uninstalled) some components of your previous desktop
which are required by whole OS. So now when you uninstall Cinnamon
you also uninstall those obligatory components. Instead (or rather
before) uninstalling them you'd have to reinstall your previous
desktop. But that's my guess only.

It may be a bug or it may not be a bug. We will not know without
trying to reproduce. Or it may be a bug but not worth fixing because
probably a workaround exists and probably switching desktops is
considered too advanced to be worth making easier.

Try setting clean_requirements_on_remove=False in /etc/dnf/dnf.conf. See

Cannot dnf group remove "Cinnamon Desktop"

[Jorge Gallegos]

Hi,

I found out the Cinnamon Desktop group is behaving like Hotel
California. I had ``dnf group install "Cinnamon Desktop"`` some time in
the past, and was trying to cleanup now after finishing fiddling with
it. It turns out that Cinnamon Desktop's dependencies somehow bind to
protected dependencies, i.e.

```
[root@ragnia ~]# dnf group remove "Cinnamon Desktop"
Last metadata expiration check: 2:18:50 ago on Mon May  8 07:18:18 2017.
Dependencies resolved.
Error: The operation would result in removing the following protected packages: 
dnf, systemd, systemd-udev.
```

Is this intended? A cursory search in bugz turns out no real results,
but wanted to make sure if maybe I am missing something here, if not I
will be opening a new bug.


Cheers
