我升级debian到wheezy，并得到错误与mysql-server所以我删除它。 现在我不能重新安装它。 我得到：
$ sudo apt-get install mysql-server ... Unpacking mysql-server (from .../mysql-server_5.5.30+dfsg-1.1_all.deb) ... Processing triggers for man-db ... gdbm fatal: malloc error Setting up mysql-server-5.5 (5.5.30+dfsg-1.1) ...

（完整的输出在http://pastebin.com/7WpSEDbx ）
注意到有些令人担忧的gdbm fatal: malloc error 。
我如何获得mysql ？
