Update from V115 to V117 Breaks Python

[bbmak]

Hi,
After I upgrade from V115 to V117, I realize V117 breaks my python script with urllib library.
When I re-write the V115 image, the python is working again.
Not sure is this a bug or something else?

update:
my apt-get update also breaks after update to V117

Hi BBmak,

When you say "breaks your python script and apt-get update", please could you provide us with more information. Either a screenshot of the error/issue when it occurs, or a copy and paste over SSH.

With the requested information above, we should be able to assist you

Sure, Thank you for the reply. Here is the output of one of the scripts that I am using to update the noip ddns.

Might be related to the recent proxy support in DietPi.

As per this page, please try:

Ok, doing os.environ['http_proxy']='' before importing urllib2 seems
to do the trick for that.

Failing that, try running the script with python 3:

Code: Select all

python3 myscript.py

You might need to:

Code: Select all

apt-get install python3

I tried your suggestions, python3 seems working, but I have to change a lot of my codes in order to make my scripts work in python3.

When I use os.environ['http_proxy']='' before importing urllib2, i got the same output as previous.

using V117 also break my apt-get update. It throws me an error as well.

Strange. Is it possible the urllib2 library you have is only python3 compatible?

The apt-get update error, could you paste the error or screenshot it please? There may be a issue with a repo that is causing this. Could even be linked to your python issue if packages were installed from various repos.

Regarding: http://dietpi.com/phpbb/viewtopic.php?f=11&t=408#p1761

Can you paste the results of the following please:

Code: Select all

cat /etc/apt/sources.list

Please see image when I perform apt-get update after I updated to V117 from V115.

Update: Just realized that ping google.com is not working too, and ping 8.8.8.8 is working.
