Copy Failed. Some files were not uploaded successfully.

Cause

A login script on the destination host (e.g. .bashrc) that prints to stdout. scp expects to see its protocol data over the stdin/stdout channels

Resolution

  • Remove the statement or
  • Prefix the statement with: [ -n "$PS1" ] &&
    • E.g. [ -n $"PS1" ] && echo "a"
