What Should I Do If Cloud-Init Does Not Work After Python Is Upgraded?¶
Symptom¶
Take an ECS running CentOS 6.8 as an example. After Python was upgraded from 2.6 to 2.7, Cloud-Init did not work. Data, such as the login password, key, and hostname could not be imported to the ECS using Cloud-Init.
After the cloud-init -v command was executed to view the Cloud-Init version, the system displayed errors, as shown in Figure 1.

Possible Causes¶
The Python version used by Cloud-Init was incorrect.
Solution¶
Change the Python version used by Cloud-Init to the source version. To do so, change the environment variable value of /usr/bin/cloud-init from the default value #!/usr/bin/python to #!/usr/bin/python2.6.
