Perhaps there is something with my local copy of the v13 docker image but svn / subversion seems to be missing. I tried the all-in-one and the multiple container variant. Can anyone confirm this? I filed some details here OP-13246

Simple check - even if git or no repo connection is used: open the commandline in the v13 container and try to reach svn. Thanks.

Confirmed and fixed in next release. See OP-13246
