On iCyPhy, the <code>legacy</code> workgroup svn update worked until the <code>legacy</code> workgroup wiki was added.  Then update failed:
<pre>
Working Directory: /home/www/cvswww/www.icyphy.org/legacy
Command:

/home/www/bin/vc-svn update --username vc@icyphy.org --config-dir /home/vc/.subversion-icyphy 2>&1 

Updating module legacy:
     svn: REPORT of '/svn/projects/icyphy/legacy/!svn/vcc/default': Could not read chunk size: Secure connection truncated (https://repo.eecs.berkeley.edu)
Done!
</pre>

<h2>Workaround</h2>
It seemed like the directory was corrupted somehow.

I was able to check out a copy of the tree and replace it.

I had to copy the wiki/uploads and wiki.d files from the old to the new

<h2>Wiki Creation Command</h2>
Below is how the <code>legacy</code> workgroup wiki was added.

<pre>
-bash-4.1$     /home/www/php/bin/svnwiki www.icyphy.org legacy
A         wiki

If you are prompted for the password, then enter it. Hint: k
If you are prompted to save the password in clear text, then do so.

ATTENTION!  Your password for authentication realm:

   <https://repo.eecs.berkeley.edu:443> UCB/EECS Subversion Repository

can only be stored to disk unencrypted!  You are advised to configure
your system so that Subversion can store passwords encrypted, if
possible.  See the documentation for details.

You can avoid future appearances of this warning by setting the value
of the 'store-plaintext-passwords' option to either 'yes' or 'no' in
'/home/vc/.subversion/servers'.
