The Ruby openssl extension was not compiled. Missing the OpenSSL lib?

In this Question Sam Ruby said I should install libssl-dev and I try it with:

sudo apt-get install libssl-dev

Now I got this error:

dpkg: Fehler: Parsen der Datei »/var/lib/dpkg/available«, nahe Zeile 10:
 package name fehlt
E: Sub-process /usr/bin/dpkg returned an error code (2)

Could somebody explain me what is the problem and how can I solve it, please.

Solution

  • Your /var/lib/dpkg/available file got corrupted. You can fix it with the following:

    1. Backup your existing /var/lib/dpkg/available via: sudo cp /var/lib/dpkg/available /var/lib/dpkg/available.backup

    2. Then run the following, this will clear the file: sudo dpkg --clear-avail

    3. You should be able to install packages again as usual: sudo apt-get update && sudo install libssl-dev

    Source: Ubuntu dpkg manpage
