Ubuntu 14.04 Repositories: universe, main

Ran apt-get update

Ran apt-cache policy libssl1.0.0

ddew@ddew-wsl:~$ apt-cache policy libssl1.0.0
libssl1.0.0:
  Installed: 1.0.1f-1ubuntu2.11
  Candidate: 1.0.1f-1ubuntu2.11
  Version table:
 *** 1.0.1f-1ubuntu2.11 0
        100 /var/lib/dpkg/status
     1.0.1f-1ubuntu2 0
        500 http://archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages

Was surprised to see that the version advertised as the candidate is not the same as what is available from main and that the version available from main is older than the version that is already installed.

Attempted to install libssl-dev

ddew@ddew-wsl:~$ sudo apt-get install libssl-dev

The following packages have unmet dependencies:
 libssl-dev : Depends: libssl1.0.0 (= 1.0.1f-1ubuntu2) but 1.0.1f-1ubuntu2.11 is to be installed
              Recommends: libssl-doc but it is not going to be installed

Out of curiosity, ran apt-cache policy libssl-dev

ddew@ddew-wsl:~$ apt-cache policy libssl-dev
libssl-dev:

  • I have two PPAs configured. One is for Chromium. The other is for VirtualBox. I wonder if either of those might have caused the installation of libssl1.0.0 version 1.0.1f-1ubuntu2.11 – Doug Dew May 31 '15 at 01:29
  • Nope. I just checked some installation dates. It seems that libssl1.0.0 was installed before anything from either of those two PPAs was installed. – Doug Dew May 31 '15 at 01:39
  • According to the published package list, both libssl-dev and libssl1.0.0 should be at version 1.0.1f-1ubuntu2.11: – Doug Dew May 31 '15 at 01:41

  • So, it seems that my local package database for main is not up to date. But, I've run apt-get update. So, I'm not sure what to do next. – Doug Dew May 31 '15 at 01:43

Same problem on Ubuntu 16.04

$ apt-cache policy libssl1.0.0    
libssl1.0.0:
  Installed: 1.0.2g-1ubuntu4.5
  Candidate: 1.0.2g-1ubuntu4.5
  Version table:
 *** 1.0.2g-1ubuntu4.5 100
        100 /var/lib/dpkg/status
     1.0.2g-1ubuntu4.1 500
        500 http://mirror.uoregon.edu/ubuntu xenial-updates/main amd64 Packages
        500 http://mirror.uoregon.edu/ubuntu xenial-security/main amd64 Packages
     1.0.2g-1ubuntu4 500
        500 http://mirror.uoregon.edu/ubuntu xenial/main amd64 Packages

$ apt-cache policy libssl-dev
libssl-dev:
  Installed: (none)
  Candidate: 1.0.2g-1ubuntu4.1
  Version table:
     1.0.2g-1ubuntu4.1 500
        500 http://mirror.uoregon.edu/ubuntu xenial-updates/main amd64 Packages
        500 http://mirror.uoregon.edu/ubuntu xenial-security/main amd64 Packages
     1.0.2g-1ubuntu4 500
        500 http://mirror.uoregon.edu/ubuntu xenial/main amd64 Packages

So I fixed it with

sudo apt-get install libssl1.0.0=1.0.2g-1ubuntu4.1

    I had to go for apt-get install libssl1.0.0=1.0.2g-1ubuntu4. Good tip – Tapajit Dey Oct 24 '17 at 19:52

    You're a legend! My newly installed Debian 11 somehow got utterly broken, but I managed to save it with apt-get install libssl1.1=1.1.1k-1! Thanks! – Saustrup Sep 09 '21 at 20:01
