Subversion client too old

This is a workaround to fix a problem I had with my svn client after upgrading to Eclipse Ganymede and Subclipse plugin last week. It is based on scattered information I found on the web and that I managed to put together. Hopefully it will save someone some time (somewhere... something... somehow...).
Basically, I had ended up with an svn client 1.4 on my system (ubuntu 8.04) whereas subclipse used a somehow bundled latest version 1.5. So everything went fine, as long as I did my svn work from within eclipse. Until one day (today) I had to do an
svn up
from the shell (we use maven modules and this time I had to update from the parent pom location). Then I got this message
This client is too old to work with working copy '.'; 
please get a newer Subversion client.
This was baffling, as
apt-get install subversion
told me that I had the latest package installed. After some googling, it turned out that svn 1.5 upgrades your working (local) files in a way that it's incompatible with svn client 1.4. To cut it short, I decided to upgrade my svn client.

Here are the steps to follow:

  • At the moment, subversion 1.5 deb package is still considered experimental, so you'll need to add a line to your
    /etc/apt/sources.list
    like this:
    deb http://ftp.it.debian.org/debian experimental main
    (You can choose a different mirror here http://packages.debian.org/experimental/i386/subversion/download)

  • Then do
    apt-get update
    to update your deb repositories

  • Finally
    apt-get install subversion
    to update your svn client to version 1.5. I gladly ignored the warnings about some non authenticable packages (those coming from the experimental repository).

Now everything is working fine.

I had to help someone with a similar issue but they were on windows. I had to use a beta version of subversion 1.5. You have to google for it though, I had a hard time finding it.

No chance you're on a Mac is there? How about Versions?

Do you always get the gpg error when adding experimental sources?

W: GPG error: http://ftp.au.debian.org experimental Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A70DAF536070D3A1
W: You may want to run apt-get update to correct these problems

Yes, I had it too but I ignored it and proceeded to install the new svn client version with no problem at all.
