#264511 — Synaptic Problem

I have just reinstalled Bookworm.

Unfortunately, when I tru tto use synaptic I get the following 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.

Unfortunately, Google has not been of any help.

A solution to the problem would be appreciated.

Tanks in advance.

brscan4 is not in the official Debian repos. Perhaps you have installed
it from another source which has disappeared.

Superficial Internet search suggests that it is a Brother thing.

That will depend on whether you need that brscan4 package. Do you
have a Brother scanner?

Indeed it is.

Brother have some installation helper script, but that is not really 
playing nicely with the idea of using remote repos for installation. It 
may be simplest to use dpkg to uninstall the brscan4 package, do the 
necessary upgrades etc., and then install the brother stuff again.

That way, you'll also have relatively up to date Brother drivers.

If you want to avoid the odyssey through Brother's web site, have a look 
at https://pieterhollander.nl/post/brother-printer-debian/ and consider 
just believing them.

Cheers,

Arno

Does synaptic still insist on the brscan4 package after it is uninstalled?

In that case, there must be some dependency involved. I have not used 
synaptic a lot, but doesn't it give an explanation *why* it needs the 
package?

Cheers,

Arno

A solution may already exist on your machine if it knows about brscan.

Brother has a deb containing their smartinstaller as a bash script, 
named in my case "linux-brprinter-installer-2.2.1-1" or your can get the 
latest version from brothers sites, visit with firefox.

Unpack it, run it from a cli, it asks for the model number string of the 
printer or scanner, goes to brother'sown linux repo and downloads the 
latest version available for that device and installs and configures it 
to Just Work with cups IF you have removed cups-browsed thereby 
disallowing cups from setting up the default printer driver which cannot 
drive the printer in anything but waste paper mode. Brothers own drivers 
support every feature the printer has, accessible from the web interface 
cups serves at localhost:631. Despite the poor publicity I've seen about 
factory drivers, brothers drivers for linux work 100% here. Linux 
support is excellent for their products.



Cheers, Gene Heskett.

Thank you for your encouraging reply. I have the Brother MCF-L2710DW 
Laser printer and am very pleased with it. I followed your directions 
and ran:

sudo bash linux-brprinter-installer-2.2.3-1


Here are the CUPS results:

Description: 	MFCL2710DW
Location: 	
Driver: 	Brother MFCL2710DW for CUPS (grayscale, 2-sided printing)
Connection: 
dnssd://Brother%20MFC-L2710DW%20series._ipp._tcp.local/?uuid=e3248000-80ce-11db-8000-b42200417fc9 

Defaults: 	job-sheets=none, none media=iso_a4_210x297mm sides=one-sided

I ran "Prnt Test Page" anmd got:

Description: 	MFCL2710DW

Connection:

Well since you specced A4 paper, did you have A4 paper in the tray? and 
of course, did it work? You may need to goto locolhost:631 with your 
browser and configure the options to suit your environment. Also, that 
uuid is unique to that printer, so it must be correct. else you'd 
collect a no such device error. An ls of /dev/serial/by-id might serve 
as a checking src. klipper, the better 3d printer driver, uses that to 
make sure its driving the right printer since usb has rather poor id 
mechanisms. from my printers output:
root@mkspi:~# ls -l /dev/serial/by-id
total 0
lrwxrwxrwx 1 root root 13 Dec  3 01:17 
usb-Klipper_rp2040_E5D94D950DCD5658-if00 -> ../../ttyACM0
the E5D9..... is a unique to that chip serial number, no other rp2040 
has it.  So do all the stm32 controller chips.
Unforch that is not always true, as witnessed by this machine:
gene@coyote:~/src/klipper-docs$ ls -l /dev/serial/by-id
total 0
lrwxrwxrwx 1 root root 13 Dec  7 11:39 usb-1a86_USB2.0-Serial-if00-port0 
-> ../../ttyUSB1
lrwxrwxrwx 1 root root 13 Dec  7 11:39 
usb-FTDI_USB_HS_SERIAL_CONVERTER_FTDHG45D-if00-port0 -> ../../ttyUSB0
where there aren't any chip serial numbers, but cups seems to have other 
ways of assuring its driving the correct device as a printer. One of 
those is actually driving a CM11A X10 home controller.

Probably more info than you need if the test page worked,
