@mikini, I actually had a similar situation with apt-get wanting to remove npm. That's due to npm depending on node-gyp, which depends on nodejs-dev, which depends on libssl-dev. You need to install an old version of that package as well, you can't have a new libssl-dev package and an old libssl package installed together.
So something like: apt-get install libssl1.0.0=1.0.1f-1ubuntu2 libssl-dev=1.0.1f-1ubuntu2 npm node-gyp nodejs-dev should ensure you'll get compatible older versions installed, and still have the Node.js stuff. However, that 1.0.1f-1ubuntu2 version seems quite old and could contain lots of vulnerabilities... I'd be wary of using it unless your server won't be doing SSL termination for clients from untrusted sources. Either because you SSL terminate at a load balancer, a reverse proxy or the like, or because your server is only accessible from a private network, like mine. A better option would be to try and source the libssl and libssl-dev binaries for the immediately preceding 1.0.1f-1ubuntu2.19 version from somewhere else. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssl in Ubuntu. https://bugs.launchpad.net/bugs/1626883 Title: libssl 1.0.2g-1ubuntu4.4 causes PHP7 SSL cert validation to segfault Status in openssl package in Ubuntu: Confirmed Bug description: Last night unattended-upgrades upgraded the openssl packages (libssl1.0.0, libssl-dev, openssl) from version 1.0.2g-1ubuntu4.1 to version 1.0.2g-1ubuntu4.4 on a CI build server. Then everything that used PHP to connect to a HTTPS site started crashing when verifying the server cert.

Of course, this might just as well be due to some insufficient error handling or otherwise improper libssl usage in php7.0, but the net effect is that the latest libssl makes the latest php7.0 in the stable Ubuntu 16.04 LTS version crash.
