Any git svn operation leading to the below error.

Have installed Alien SVN using the command cpan SVN::core and have also installed subversion perl binaries.

Googled but couldnt get it to work. Tried the solution mentioned here but no luck. Can someone please let me know how to resolve this issue?

@xxfelixxx, Yup i initially ran the "git svn init " which ran successfully. And then when i ran the "git svn fetch", i ended up getting the error which i have posted in the question. — Iowa, May 15 '18 at 07:59
Have you set up a different svn repo and set it up to be the remote of this git svn repo? — xxfelixxx, May 15 '18 at 08:14
Precisely, i have a SVN repo running over http, and initialize it using 'git svn init http://IP:PORT/svn/trunk/Automation/UCM', then i set the remote using the command 'git remote add origin http://IP:PORT/svn/trunk/Automation/UCM' and then do a 'git svn fetch'. The last command is failing with the error which i have posted in the question. — Iowa, May 15 '18 at 08:20

I upgraded git to the latest version, which is 2.17, and still getting the same error. — Iowa, May 15 '18 at 08:35

The cpan SVN::Core installation uses the SERF libraries (for HTTP scheme handling) only if it finds them. Try and install the SERF-dev library:

$ sudo apt-get install libserf-dev

then re-install (re-build) SVN::Core:

$ cpan
...
cpan[1]> install SVN::Core

you should see this configure output:

configure: serf library configuration via pkg-config
checking for serf-2 library... no
checking for serf-1 library... yes
checking serf library version... 1.3.8
checking serf version is suitable... yes
checking was serf enabled... yes
