Binary package “e2fsprogs-udeb” in ubuntu bionic

stripped-down versions of e2fsprogs, for debian-installer

 This package is an e2fsprogs package built for a reduced size, so that
 it can help to save space in debian-installer.
 .
 Don't attempt to install this package, it has no support for a couple of
 features you surely want. Anyway it should refuse to install.
