I am using Kubuntu 14.4 and have

$ ssh -V
OpenSSH_6.6.1p1 Ubuntu-2ubuntu2.8, OpenSSL 1.0.1f 6 Jan 2014

installed. I have trouble to log in into some servers I need to get into and the support thinks, it is because my ssh is too old. How can I upgrade my ssh version to the current version (openssh-7.5p1 if I am not mistaken) without destroying my OS? The support said it might be possible to install ssh 7.5 seperately using the environment variable LD_LIBRARY_PATH.

  • Use apt-get? Is your version of ssh package managed? – Raman Sailopal Oct 2 '17 at 13:25
  • @RamanSailopal: Kubuntu 14.4 is from 2014. So ssh in the repos is old (as old as mentioned in the question). – Make42 Oct 2 '17 at 13:29

    Best thing I would suggest would be to create a test environment, build the latest version of ssh from source and verify that everything works as expected. – Raman Sailopal Oct 2 '17 at 13:34

Like @RamanSailopal said, the best thing would be to create a test environment and build the latest from source.

cd /tmp
wget ftp://ftp3.usa.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-7.5p1.tar.gz
tar -zxvf openssh-7.5p1.tar.gz
cd openssh-7.5p1
./configure
make
make install

However, I suggest you upgrade from 14.4 to the latest version of Kubuntu, not the best idea to use "End of life" OS's.

  • A virtual machine is one option. – Hunter.S.Thompson Oct 2 '17 at 16:34
