Using apt install --ignore-depends causes apt to stop working and insist on running --fix-broken install

Question

I was following an article like this one:

How can I install a package without installing its dependencies?

sudo dpkg --install --ignore-depends=libssl1.1 easytether_0.8.9_amd64.deb

That works great, libssl1.1 isn't installed (I've manually sym linked to the library for this legacy app).

But now all future installs fail and depend I run --fix-broken install:

$ sudo apt install iw
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 easytether : Depends: libssl1.1 (>= 1.1.0) but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I can't fix it because libssl1.1 isn't supported and isn't a package I can install, hence my need to sym link to the specific .so file that legacy app needs. If I run apt --fix-broken install it will simply uninstall the .deb file from above.

But how can I force apt to forever ignore the fact that it's missing that dependency.

Answer 1

Apparently support for libssl1.1 got deprecated here the package page because of security reasons.

• First, ask the devs of easytether to switch to libssl3.
• But in the meantime someone made a back port here install the PPA and you should be set.
• And also, in the future, for package problems use http://packages.ubuntu.com
