I have not used linux much. But I am stuck at the same error mentioned in this thread. My juju version is - 1.24.3-vivid-amd64 And below is the output that I am getting when I do "juju bootstrap". How do I go about debugging this issue. I have seen the troubleshooting videos for juju and also the documentation but I am not finding a solution to the error below - vagrant@vagrant-ubuntu-vivid-64:~$ juju bootstrap Bootstrapping environment "local" Starting new instance for initial state server Building tools to upload (1.24.3.1-vivid-amd64) Bootstrapping environment "local" Starting new instance for initial state server Building tools to upload (1.24.3.1-vivid-amd64) Installing Juju agent on bootstrap instance Logging to /home/vagrant/.juju/local/cloud-init-output.log on remote host Installing package: curl Installing package: cpu-checker Installing package: bridge-utils Installing package: rsyslog-gnutls Installing package: cloud-utils Installing package: cloud-image-utils Installing package: tmux Bootstrapping Juju machine agent Reading package lists...
