I am running buster on my Linux platform.
Perhaps consider updating to Bullseye (Debian 11) as the latest stable
version. Printer driver support has been improved and many printers
now run "driverless" and work out of the box.
I have installed a new Brother Laser print using the current Brother Linux
installer.
If this is the Brother installer from Brother - a commercial product - we
probably can't help. Take it up with Brother? How did you download it - from
where - and how did you install it
The printer is working, but when I try running Synaptic I get an error:
E: The package brscan4 needs to be reinstalled, but I can't find an archive
for it.
E: Internal error opening cache (1). Please report.
That suggest that this wasn't a Debian package recognised by packaging
databases, maybe.
I tried Goggling but didn't find any solutions. Then I tried uninstalling
the offending package and got an error:
comp@AbNormal:~/Downloads/Brother-MFC-L2710DW$ sudo ./uninstaller_brscan4
[sudo] password for comp:
dpkg: error processing package brscan4 (--purge):
package is in a very bad inconsistent state; you should
reinstall it before attempting a removal
Errors were encountered while processing:
brscan4
Not properly installed: you might
apt-get --fix-install
If the worst is the worst,
dpkg --configure -a
might help. The last resort is forcibly deleting bits of package and manually
amending the package database which is somthing you _really_ don't want to do
unless absolutely unavoidable.
That failed. Fin
ally, I tried reinstalling with dpkg, which also failed.
The complete log is attached.
At this point I am completely beyond my depth in even starting to understand
the error messages, let alone solving it.
Help will be much appreciated.
Thanks in advance.

Manually delete all files under /opt/brother/scanner/* and try again?
Hope this helps in some smwall way at least. With every good wish, as ever,
