How do I avoid "'/usr/bin/aptitude safe-upgrade' failed: FATAL -> Failed to fork"?
I have an Ubuntu 14.04 droplet which I set up with Ansible. When I run my playbook it currently fails when trying to upgrade APT packages:
'/usr/bin/aptitude safe-upgrade' failed: FATAL -> Failed to fork.
I’m not sure what this means or how to get round it.
The playbook’s worked fine plenty of times before on this droplet. My droplet was recently migrated as part of some DO improvement and this is the first time I’ve run the playbook since then.
