CMK version: Checkmk Enterprise Edition 2.3.0p11
OS version: Debian 12
Error message: AttributeError: module ‘urllib’ has no attribute ‘urlencode’
Hello everybody,
today we updated our site to the most recent 2.3.0p11. Before our site was running some 2.2-version.
This topic gives a solution for people who have the same problem, and probably it is also interesting for the Checkmk-staff, as I think the adjustment I made should be delivered from checkmk directly, or at least noted as an “incompatible todo”-werk.
After the update, our notification-rules which are using the mobilant-plugin didn’t work anymore:
Seems like the script is now using python 3+. Before the update, it was running with python 2.7+ just fine.
In the Werks I saw some various changes about python. However, none of them are connected to this mobilant-plugin. Looking at the error AttributeError: module ‘urllib’ has no attribute ‘urlencode’, and the point that urlencode is found in urllib.parse towards Python 3+, I assume that the mobilant-pythonscript is now called with python3+.
So I think it is missing in the werk-list / missing as an “incompatible todo”-werk, or Checkmk forgot about updating the mobilant-pythonscript in omd/versions/2.3.0p11.cee/share/doc/check_mk/treasures/notifications/mobilant, so it runs under python 3+, without any manual adjustments.
The solution was changing some lines in the script:
- Change the shebang from #!/usr/bin/env python to #!/usr/bin/env python3 (not important, but to make it clear which version is used)
- Change the imports from import sys, os, urllib to import sys, os, urllib.parse, urllib.request
- Change the usage of urlencode from urllib.urlencode to urllib.parse.urlencode
- Change the usage of urlopen from urllib.urlopen to urllib.request.urlopen
Greetings, Julien
