Distrobox Won't Update Debian Container

I’m not sure what to do with this. For the last week or so, my Distrobox of debian-toolbox:latest won’t update. From within Kontainer, when I hit the Upgrade All “button,” it starts the upgrade process, things scroll by for a bit and then the upgrade window just disappears. If I use the Open Terminal button for the container in Kontainer and run:

sudo apt update && sudo apt upgrade

I get:

Hit:1 Index of /debian unstable InRelease
Hit:2 https://updates.signal.org/desktop/apt xenial InRelease
41 packages can be upgraded. Run ‘apt list --upgradable’ to see them.
You might want to run ‘apt --fix-broken install’ to correct these.
Unsatisfied dependencies:
systemd-sysv : Depends: systemd (= 261~rc4-1) but 261-1 is installed
Error: Unmet dependencies. Try ‘apt --fix-broken install’ with no packages (or specify a solution).

If I run

sudo apt --fix-broken install

I get:

which does not bode well. And, sort of as expected, if I re-run

sudo apt update && sudo apt upgrade

I get the same error I started with.

EDIT: Sorry, I should have included that I’m on Bazzite v4.20260608 (KDE Desktop).

A bit more oddness. The original error says:

Unsatisfied dependencies:
systemd-sysv : Depends: systemd (= 261~rc4-1) but 261-1 is installed

But, unless I’ve lost even more of my mind than I think I have, 261-1 looks like it’s a later version than the 261~rc4-1 it wants. Plus, if I run:

systemctl --version

from within the Distrobox terminal, that gives me:

systemd 261 (261.1-1)

which looks like it’s a later version than both 261~rc4-1 and 261-1. AND, if I run:

sudo apt list --upgradeable

in the Distrobox terminal to see what it wants to upgrade, at the very end I see:

systemd-sysv/unstable 261.1-1 amd64 [upgradable from: 261~rc4-1]

which sure looks like it’s saying it’s actually running the 261~rc4-1 it wants but can upgrade to 261.1-1 that the --version commands says is already there.

Maybe no one here can solve this. But, can anyone point me in the right direction of where the problem is? Is this a Distrobox issue? A Debian issue? A Bazzite (or any OCI, immutable, atomic OS) issue? Or, a combination of the above?

EDIT: Also, I tried:

sudo apt full-upgrade

which, I thought, was supposed to force things to upgrade by uninstalling dependency conflicts and re-installing what it needs. But, that gives me the same error that I started with. Is there any way to fix this Distrobox?

When you created the container did you toggle “Init process”?

I finally gave up and re-created the distrobox container (for my use, anything debian-based is fine, so I used Kali instead of Debian this time).
