How to satisfy dependencies?

Question

linux

Comrades, help with this situation:

....
dpkg: far2l: dependency problems, but we're still configuring at your direction:
far2l depends on libssl-dev, however:
Package libssl-dev is not installed.
~# apt install libssl-dev
Reading package lists... Done
Building dependency tree
Reading status information... Done
You might want to use "apt-get -f install" to fix these errors.
Packages with unmet dependencies:
libssl-dev : Conflict: libssl1.0-dev but 1.0.2s-1~deb9u1 will be installed
libssl1.0-dev : Conflict: libssl-dev but 1.1.0k-1~deb9u1 will be installed
E: Unmet dependencies. Try "apt --fix-broken install" without a package name (or find another solution).

far2l needs libssl-dev and libssp-dev, but when I install libssh-dev I get this:

~# apt install libssh-dev
Reading package lists... Done
Building dependency tree
Reading status information... Done
You might want to use "apt-get -f install" to fix these errors.
Packages with unmet dependencies:
libssh-dev : Depends: libssl1.0-dev but it will not be installed
E: Unmet dependencies. Try "apt --fix-broken install" without a package name (or find another solution).

How to be? What to do?

Answer 1

always going down in that case..i.e. a step further try putting libssl1.0-dev etc.

Answer 2

The package requires a newer/older version of libssl-dev. Or the repositories are crookedly connected.
The most optimal way is to download the source code of the package and rebuild it for the target system. The rest is unnecessary dances with tambourines.
