The dependencies for the package usrmerge available in Beowulf are

debconf (>= 0.5) | debconf-2.0
perl:any
libfile-find-rule-perl

as given in https://pkginfo.devuan.org/stage/beowul … ge_21.html

since usrmerge is not available for Ascii, but debconf 1.5.61 and perl are already installed in any standard ascii installation , after installing 'libfile-find-rule-perl' using apt or apt-get, download "usrmerge" from either Devuan Beowulf or Debian Buster and install it manually using

sudo dpkg --install usrmerge_21_all.deb

You will receive a prompt that the procedure cannot be reversed, and when confirmed the package will be successfully installed.

if you do this on an installation where /usr and / are in seperate partitions, you should run

sudo update-initramfs -k all -u

before you reboot.
