Debianパッケージnpmをインストールしてapt-getを有効にしてlibssl-devを削除してみてください。

:~/$ uname -a
Linux hostname 4.9.0-4-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.51-1 (2017-09-28) x86_64 GNU/Linux

私の考えには明確な依存関係ツリーがあり、破損したパッケージがないようです。

:~/$ sudo apt-get check
Reading package lists... Done
Building dependency tree

ただし、インストールしようとすると、npmapt-getは次のものを削除しようとしますlibssl-dev。

:~$ sudo apt-get install npm
