    <p>I have Karmic Koala which has Python 2.6 installed by default.</p> <p>However I can't run any Python App Engine projects because they require Python 2.5 and python ssl.</p> <p>To install ssl I installed python2.5-dev first while following <a href="http://groups.google.com/group/google-appengine-python/browse_thread/thread/92583bea0395c57a" rel="noreferrer">some instructions I found elsewhere</a>.</p> <pre><code>sudo apt-get install libssl-dev sudo apt-get install python-setuptools sudo apt-get install python2.5-dev sudo easy_install-2.5 pyopenssl </code></pre> <p>However, I am afraid this is not good for my Ubuntu installation since Ubuntu expects to see version 2.6 of Python when you type 'python' on the command line. Instead, it says '2.5.5'. </p> <p>But App Engine still doesn't work after all this. I continue to get an SSL-related error whenever I try to run my Python app:</p> <pre><code>AttributeError: 'module' object has no attribute 'HTTPSHandler' </code></pre> <p>UPDATE1: Just checked whether SSL actually installed as a result of those commands by typing this:</p> <pre><code>$ python2.5 Python 2.5.5 (r255:77872, Apr 29 2010, 23:59:20) [GCC 4.4.1] on linux2 Type "help", "copyright", "credits" or "license" for more information. &gt;&gt;&gt; import ssl Traceback (most recent call last): File "&lt;stdin&gt;", line 1, in &lt;module&gt; ImportError: No module named ssl &gt;&gt;&gt; </code></pre> <p>As you can see, SSL is still not installed, which explains the continuing App Engine error.</p> <p>UPDATE2:</p> <p>I tried to revert to the original default version of Python by doing this:</p> <pre><code>sudo ln -s /usr/bin/python2.6 python </code></pre> <p>in my <code>/usr/bin/local</code> folder.</p> <p>Now I get Python 2.6.4 when I type 'python' on the command line.</p> <p>But this doesn't solve my App Engine SSL issue.</p> <p>If anyone knows how I can dig myself out of this hole, I would appreciate it.</p>

    1. COAre you trying to do something with SSL on GAE? If not, you shouldn't need the ssl module installed. Could you share what code is causing that error to be raised?

    2. COI'm just calling dev_appserver.py on the "new_project_template" that comes with App Engine. It happens on the other demo projects too. I'm not doing anything with SSL myself.

    3. CODo you get any more Details about the error when you start dev_appserver.py with the "-d" (debug) flag ? I'm running the SDK on lucid with python 2.6.5 and can't confirm any problems due to that so far.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
