I'm on Devuan Stable and refuse to use anything other then apt for installing packages. Appimage and flatpack (as well as snap) are fundamentally windows-fying the Linux install system b/c that's what we do on Windows Yes, on Win-OS, but Linux is damn well not Win-OS!

Rant over

Brother has an installer for its devices. Just a script, runs on pretty much any Linux version and does the work of installing the correct drivers for you. See the Brother Linux page to find it.

Do first:

apt-get --allow-releaseinfo-change update

If you haven't already, you need to update/install usrmerge before upgrading your system;

apt-get install usrmerge

Let it complete, can take some time. Then:

apt-get dist-upgrade

Again, let it finish before changing any packages (install/uninstall, etc)

Why are you installing manually? Just use the automated installer, it'll fix pretty much anything.

Oh wait, different forum

Boot from the clone drive, become root, then this command:

blkid /dev/sd* >> /etc/fstab

This lists all disks and every partition on that disk with their respective UUID's in /etc/fstab. If you type in the command by hand, make sure you have the double arrow! Otherwise your fstab file is gone :-\

Next, open /etc/fstab in a graphical text editor like Pluma, so you can easily copy/paste the UUID's into the correct entries. Once you're certain everything is in the right place, either remove all UUID entries from the earlier command or better, comment them out so you have something to fall back on in case something went haywire :-{ Save the fstab file and reboot.

Thx for that reply. Won't these keys need to be de-registered? (they're found in /etc/apt btw)

Rename the script cifsdown.sh, copy to /etc/init.d, give it executable rights like you already did then create a symlink in /etc/rc0.d Make sure the sym-link in /etc/rc0.d is named K01cfisdown.sh DO NOT deviate from that name, as the order of shutting down services is important.

Alternatively, execute the following line by line:

sudo su #only if you use sudo, otherwise just use su instead
mv /etc/NetworkManager/dispatcher.d/pre-down.d/umount.sh /etc/init.d/cifsdown.sh
chmod +x /etc/init.d/cifsdown.sh
ln -s /etc/init.d/cifsdown.sh /etc/rc0.d/K01cifsdown.sh

You can use cp instead of mv to keep a copy in the original location. That's the difference between cp and mv: cp leaves a copy, mv (move) doesn't. Make sure you disable the script left there before rebooting:

chmod -x /etc/NetworkManager/dispatcher.d/pre-down.d/umount.sh

HTH!

Aaaaannnnddd I'm stuck   Even after attempting to install usrmerge with aptitude, installation fails b/c of the above failure :-{ Apt does work, so why not aptitude?

If you want to de-clutter your system at all, start with a source-based distro, not Devuan nor Debian. Consider Gentoo, Arch, LFS or Slackware. You'll learn a lot but boy that learning curve is steep! :-\
