I am trying to access an SVN repository in Eclipse. I found out how to install libsvn-java and point Eclipse at it. But the error I get is something like a plugin requires libsvnjavahl-1 v.1.11 The standard release for 18.04 is 1.9.

I found a web site that tells how to get 1.11. Unfortunately it doesn't work exactly as I expected. This is the page I found:

The problem shows up when I run
sudo apt-get update

Here is the error:
N: Skipping acquire of configured file 'svn111/binary-i386/Packages' as repository 'http://opensource.wandisco.com/ubuntu bionic InRelease' doesn't support architecture 'i386'

Not sure where to go from here.
