Ubuntu 12.04 is far old, and not mantained anymore. But many peopole still use it, and still use certbot-auto, the generic bash script used to obtain Letsencrypt certs.
The script updates itself every time it’s run, but unfortunately the current version (0.32.0 onwards) won’t run anymore with the following error:
root@server-web:/usr/local/bin# ./certbot-auto certificates Upgrading certbot-auto 0.31.0 to 0.34.0… Replacing certbot-auto… Creating virtual environment… Installing Python packages… /opt/eff.org/certbot/venv/bin/python: No module named pip.main; 'pip' is a package and cannot be directly executed Traceback (most recent call last): File "/tmp/tmp.9vckIRVgVf/pipstrap.py", line 177, in sys.exit(main()) File "/tmp/tmp.9vckIRVgVf/pipstrap.py", line 149, in main pip_version = StrictVersion(check_output([python, '-m', 'pip', '--version']) File "/usr/lib/python2.7/subprocess.py", line 544, in check_output raise CalledProcessError(retcode, cmd, output=output) subprocess.CalledProcessError: Command '['/opt/eff.org/certbot/venv/bin/python', '-m', 'pip', '--version']' returned non-zero exit status 1
To make it work again you can use these commands, as suggested on LE’s forum by user ericb2038:
cd /usr/local/bin rm ./certbot-auto* wget https://raw.githubusercontent.com/certbot/certbot/75499277be6699fd5a9b884837546391950a3ec9/certbot-auto chmod +x ./certbot-auto ./certbot-auto --no-self-upgrade
This way the script will work again, but you must always run it with the –no-self-upgrade option.
Here’s a tip to make it permanent (like if certbot is being run automatically by something else, like ISPConfig). Edit /usr/local/bin/certbot-auto and add the following at line 99:
(which is before the following line:)
if [ $BASENAME = "letsencrypt-auto" ]; then
This will force the above option at every run.
