How to fix LXC file push 'Error: Path already exists as a directory: File too large'

Problem:

You are trying to copy a file to a LXC container using lxc file push, but you see this error message:

Error: Path already exists as a directory: File too large

Solution:

Add a slash (/) at the end of your path, for example:

mycontainer/root => mycontainer/root/

Working example:

lxc file push myfile.zip mycontainer/root/
