Debian Chroot and emacs-nox

[Jeffrey Walton]

Hi Everyone,

I test Debian 68k in a chroot. I am having trouble installing emacs:

ebian-chroot:/# apt install emacs-nox
Reading package lists... Done
Building dependency tree... Done
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:
emacs-nox : Depends: emacs-bin-common (= 1:28.2+1-3) but it is not
going to be installed
Depends: emacs-common (= 1:28.2+1-3) but it is not going
to be installed
E: Unable to correct problems, you have held broken packages.

Does anyone know how to install emacs-nox on this machine?

Thanks in advance.

Perhaps your setting for apt preclude installing depends ? Please try apt
install the dependa indicated

Thanks Brian.

How do I solve the problem of unmet dependencies in emacs-bin-common
and emacs-common?

about the failure to install emacs-nox on Debian on M68K.

I too have seen that, and just did a fresh try:

# apt-get install mailutils emacs-common emacs-bin-common
...
The following packages have unmet dependencies:
emacs-bin-common : Depends: emacs-common (= 1:28.2+1-3) but
1:28.2+1-6 is to be installed

That looks to me like a messed-up dependency chain in the apt package
system on this platform, using requirements of exact version matches,
rather than greater-than-or-equal version checks.

Packaging systems really do need consistency checkers, so that broken
dependencies are caught before packages are made available to end
users. I have seen this happen on numerous flavors of Unix-family
O/Ses: it is not unique to Debian on M68K.

You have run into a situation that I have decribed in this older mailing list
post on the debian-sparc mailing list in detail [1].

The issue will be resolved once I have fixed the build failure (FTBFS) of the
subversion package on m68k.

In the meantime, you can fetch the emacs-common package in the matching version
from snapshot.debian.org [2].
