No affected components available
rm -rf . is correctly refused, but clean_trailing_slashes normalizes ./// to ./ while path_is_current_or_parent_directory only matches ./.. (and /.//..), not ./ or ../. So rm -rf ./ recursively deletes the directory's contents and then prints a misleading cannot remove './': Invalid input.
Impact: all files/subdirectories in the current directory are silently deleted; the misleading error makes users miss the recovery window. Recommendation: handle trailing-slash variants in path_is_current_or_parent_directory.
Remediation: Acknowledged by Canonical; fixed in commit d0e5af23.
