apt-get is confused by brscan2 partial fail- won't install anything

[linbu2]

Background: Running kubuntu 14.04, using kdm. I have a Brother MFC7280N, and installed the brscan2 package. Nevertheless I have never been able to scan, since the device is never found. I removed (I thought) brscan2 in hopes of reinstalling.


I had installed Kompozer, and had to remove it when it started to display funky video. I have tried to reinstall it but without success. I haven't edited any config files, except to add a repository for Kompozer (failed), or done anything other than run apt-get and the software center. That is, I haven't tried any strange (to me) commands to install, remove, or modify the installed software.

I did try to install Kompozer from a .deb file and also from two tarballs. Because I really, really need Kompozer and couldn't get it to work right on this machine.


Now I can't install or remove any software using apt-get or the Ubuntu Software Center. Here's an example:
<<

<<

It's as-if wheatever I am trying to install or remove, apt-get finds that it had a problem with brscan2 and tries to remove it, giving up when it fails because it had partially succeeded before. Then it just ignores anything else (like Kompozer, or anything I want to install or remove, even when using the -f option). This is so strange that I don't have any notion of what to make of it. So I need some expert guidance. Many thanks!

your brother driver seems to be removed

pls install the drivers first, and make sure you can print and scan

after that i will guide you in to the process of installation of Kompozer

I can't install anything either (including brscan2). I do appreciate your guidance. It says brscan2 is already the latest version, but yet my scanner is never found. I've tried xsane, simple scan, and gwenview for scanning.

# apt-get install brscan2

brscan2 is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
kompozer:i386 : Depends: libatk1.0-0:i386 (>= 1.9.0) but it is not going to be installed
Depends: libcairo2:i386 (>= 1.0.2-2) but it is not going to be installed
Depends: libgtk2.0-0:i386 (>= 2.8.0) but it is not going to be installed
Depends: libidl0:i386 but it is not going to be installed
Depends: libpango1.0-0:i386 (>= 1.12.3) but it is not going to be installed
Depends: libxft2:i386 (> 2.1.1) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

BTW: I've tried 'apt-get -f install' with no packages

[Ubi_one_2014]

dpkg -s brscan2

If brscan2 is installed, have you done the 2 additional steps required for Brother scanners to be recognized by normal users?

One involves this edit:

Copy the following files under /usr/lib64/ to /usr/lib/.

For brscan2 Users:
/usr/lib64/libbrscandec2.so.1.0.0
/usr/lib64/sane/libsane-brother2.so.1.0.7
/usr/lib64/sane/libsane-brother2.so.1
/usr/lib64/sane/libsane-brother2.so
/usr/lib64/libbrcolm2.so.1.0.1
/usr/lib64/libbrcolm2.so
/usr/lib64/libbrscandec2.so.1
/usr/lib64/libbrscandec2.so
/usr/lib64/libbrcolm2.so.1

The second issue involves a situation where the scanner works using SUDO but not as a non-privileged user:

Ubuntu 9.10, 10.04, 10.10, 11.4, 11.10, 12.04, 12.10 (versions later than 12.10 aren't mentioned but I've needed to do these steps with each new install)

1. Open "/lib/udev/rules.d/40-libsane.rules" file.

2. Add the following two lines to the end of the device list. (Before the line "# The following rule will disable ..."):
If there is "LABEL="libsane_rules_end"", add the following 2 lines before "LABEL="libsane_rules_end"".

The lines to be added---------------------------
# Brother scanners
ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"

3. Restart the OS.

I hope this will get your Brother working.
