Hello,
I am trying to install Lets Encrypt on my vServer running Debian 8 by the letsencrypt autoscript letsencrypt-auto using the following commands:
git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt
./letsencrypt-auto
After a while the process stopped showing this output:
Creating virtual environment…
Updating letsencrypt and virtual environment dependencies… Error [Errno 12] Cannot allocate memory while executing command python setup.py egg_info
Exception:
