Что делать, если SVN-репозиторий слишком поздний для клиента Subversion, который сам по себе «обновлен»?

Что-то неожиданное происходит ... Я недавно обновил некоторые репозитории SVN. Теперь, когда я нахожусь на Ubuntu, я получаю следующее, когда пытаюсь обновить их:

max@ASUSN73S:~/d/some/repos$ svn up
svn: The path '.' appears to be part of a Subversion 1.7 or greater
working copy.  Please upgrade your Subversion client to use this
working copy.

Итак, да, мне пришлось обновить Tortoise на Windows из-за этого, поэтому я обновил Tortoise, и он работал. Нет, я пытаюсь обновить Subversion в Ubuntu, чтобы ускорить его, но вот что я получаю:

max@ASUSN73S:~/d/some/repos$ sudo apt-get install subversion
Reading package lists... Done
Building dependency tree       
Reading state information... Done
subversion is already the newest version.
The following packages were automatically installed and are no longer required:
  libatk1.0-0:i386 libxcomposite1:i386 nspluginwrapper libnspr4-0d:i386 libcairo2:i386 libdatrie1:i386 libgdk-pixbuf2.0-0:i386 libpixman-1-0:i386 libxinerama1:i386 nspluginviewer:i386 libxft2:i386 libthai0:i386 libjasper1:i386

Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.

Subversion уже в курсе? Нет !:

max@ASUSN73S:~/d/some/repos$ svn --version --quiet
1.6.12

Я уже выполнил команду apt-get update.

Я не помню, чтобы менял файл sources.list в этой установке, но я могу ошибаться. В случае, если это будет уместно, вот оно:
