Cannot install bash-completion because conflicting formulae are installed. util-linux: because both install `mount`, `rfkill`, and `rtcwake` completions Please `brew unlink util-linux` before continuing. Unlinking removes a formula's symlinks from /home/linuxbrew/.linuxbrew. You can link the formula again after the install finishes. You can `--force` this install, but the build may fail or cause obscure side effects in the resulting software.
