Socat depends on libreadline5 and fails to link properly.

Socat is linked with libreadline.so.5 which is not installable.

libreadline5 has no installation candidate, on my machine it's installed but I have no libreadline.so.5 file anywhere on my machine. I have every Ubuntu repository enabled, including universe, multiverse, restricted and propsed updates.

Description: GNU readline and history libraries, run-time libraries
 The GNU readline library aids in the consistency of user interface across
 discrete programs that need to provide a command line interface.

 The GNU history library provides a consistent user interface for recalling
 lines of previously typed input.

Description: multipurpose relay for bidirectional data transfer
 Socat (for SOcket CAT) establishes two bidirectional byte streams and transfers
 data between them. Data channels may be files, pipes, devices (terminal or
 modem, etc.), or sockets (Unix, IPv4, IPv6, raw, UDP, TCP, SSL). It provides
 forking, logging and tracing, different modes for interprocess communication
 and many more options.

 It can be used, for example, as a TCP relay (one-shot or daemon), as an
 external socksifier, as a shell interface to Unix sockets, as an IPv6 relay, as
 a netcat and rinetd replacement, to redirect TCP-oriented programs to a serial
 line, or to establish a relatively secure environment (su and chroot) for
 running client or server shell scripts inside network connections. Socat
 supports sctp as of 1.7.0.
