As part of KDE's migration to GitLab, we will be moving our Subversion repository to a new server. To simplify our systems, we will also move the management of SSH keys to GitLab, and we will begin limiting access to the Subversion repository only to those actively using it.
If you have commit access, to continue having access to the SVN repository, you will need to add your SSH keys on GitLab, even if you only use Subversion and won't use GitLab in the future. Then, if you're not in the list of users with SVN access, please file a sysadmin ticket and we'll add you.
Finally, the host SSH keys of the server will change, and you will get a nasty warning about it being a security issue. You should make sure the new host key fingerprint matches one of these, then remove the old one from known_hosts as the warning explains:
