IsADirectoryError occurred when migrating /usr/bin/X11 symlink in stage step
Metadata
Current evaluation
snapcraft 3.3 (2019) crashes with IsADirectoryError in _migrate_files when staging a symlink (usr/bin/X11) that points to '.'. 2701 days old, 0 comments, no labels, no maintainer interaction; old internal staging code since rewritten.
Suggested action: close stale
Reason: The report targets snapcraft 3.3 (2019) and the traceback's code path (snapcraft/internal/pluginhandler/__init__.py _migrate_files calling os.remove(dst)) no longer exists — modern snapcraft delegates the parts/staging lifecycle to craft-parts, so this specific IsADirectoryError is no longer applicable. With 0 comments, no labels, and no maintainer interaction for ~7.4 years, and the affected version long unsupported, it is both inactive and obsolete.
