check_cli_version intermittently fails

i intermittently get the following error with codedeploy which is under an ASG/ELB
More often than not it fails. I made the script skip the checks for now, but would like it to work, so i'm aware of cli requirements.

[stderr]Checking minimum required CLI version (1.3.25) against installed version (1.2.9)
[stderr][FATAL] CLI must be at least version .. to work with AutoScaling Standby

actual verison is 1.7.43:
aws --version
aws-cli/1.7.43 Python/2.7.6 Linux/3.13.0-61-generic
