# Install native dependencies for sharp, better-sqlite3, and unrar for RAR5 support.
# Real `unrar` (not `unrar-free`) is required: unrar-free doesn't support RAR5 and
# rejects the `lb` flag the parser uses. It lives in Debian's non-free repo, so we
# enable non-free in the existing deb822 sources file (adding a separate .list would
# conflict with the keyring already declared in debian.sources).
