docker: error while loading shared libraries: libltdl.so.7: cannot open shared object file: No such file or directory

[ackris]

Hi

We have installed Docker EE 17.06.2-ee-10 on three RHEL 7.4 (maipo) servers. When we executed docker version command on 2 servers, it showed the expected output. But on the third server, it is outputting the following error.

docker: error while loading shared libraries: libltdl.so.7: cannot open shared object file: No such file or directory

uname -r: 3.10.0-693.5.2.el7.x86_64

Client: Docker Enterprise Edition (EE) 2.0

Server: Docker Enterprise Edition (EE) 2.0
 Engine:
  Version:      17.06.2-ee-10
  API version:  1.30 (minimum version 1.12)

  Experimental: false

The above docker version output is from the servers which are showing intended o/p.

We have tried to find a reason for this particular error by browsing multiple stackoverflow forums, but to no avail. Is there a solution for this error?

The intended output should display proper docker outputs.

Regards & Thanks in advance

Hi

Did you found any solutions i am also facing same issue with centos 7 and docker , same things works fine with ubuntu

[cwgem]

Curious, what's the output of rpm -qa | grep libltdl7 on that third server? If it comes up blank you may want to try yum installing it.

Actually looking here it might be libtool-ltdl instead.

[vijaymuddu]

The issue was resolved by apt-get install -y libltdl7 on container

what If I'm working from Jenkins? How should I fix it via Jenkinsfile (or Dockerfile which I may also use via Jenkins) ?

ping @seemethere
Is there a missing dep on the rhel rpm manifiest?

[seemethere]

@ackris Are you able to update to the latest version of 17.06 and see if the problem still exists? If I remember correctly we're all the way up to 17.06.2-ee-21.

edit: I think I actually found the issue, submitting a PR to fix this in our next release.

I wonder if this is still the case on 17.06.2-ee-20 or above; docker/cli#1691 was backported to 17.06.2-ee20, and (I think) removes the dependency on libltdl

[thaJeztah]

Confirmed that this is no longer a dependency for current versions of Docker EE 17.06; let me close this issue, but feel free to continue the conversation
