[lxc-users] LXC containers w/ static IPs work on some hosts, not on others

[Michael Peek]

# lxc profile show
The program 'lxc' is currently not installed. You can install it by typing:
apt install lxd-client

Maybe that's part of the problem?  Am I missing a package?  Here are the
packages I have installed for lxc:

# dpkg -l | grep lxc | cut -c1-20
ii  liblxc1        
ii  lxc            
ii  lxc-common     
ii  lxc-templates  
ii  lxc1           
ii  lxcfs          
ii  python3-lxc
