Scanning / Re: c480w scanner not detected anymore

« Last post by bchemnet on September 11, 2021, 19:17:03 »

Any idea what changed?

No.  Nothing in these packages has changed, unless you manually updated to a different driver version.  I suggest using

Code: [Select]

apt list --installed > ~/installedpackages.txt

on both your desktop and laptop, then using diff to identify what Ubuntu-provided packages may have been updated on one but not the other.

Scanning / c480w scanner not detected anymore

« Last post by agre on September 10, 2021, 05:16:29 »

Code: [Select]

Description:    Ubuntu 20.04.3 LTS
Release:        20.04
Codename:       focal

I used the c480w scanning feature via network quite a lot but it stopped working on my desktop.

Network discovery is showing the printer:

Code: [Select]

$ /opt/Samsung/mfp/bin/netdiscovery -s --snmp
# DEBUG: Network printers discovery utility
ip: 192.168.178.49  slp: 0,0,0,0 snmp: 1,1,0 vendor: Samsung dsc: "C48x Series"

But sane doesn't (it is showing on the laptop - also Kubuntu):

Code: [Select]

$ sudo sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

  # No USB scanners found. If you expected something different, make sure that
  # you have loaded a kernel driver for your USB host controller and have setup
  # the USB system correctly. See man sane-usb for details.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

Any idea what changed?

Printing / Re: Howto enable SULD drivers on rasberrypi

Well, it does work, but it is not for the faint of heart.
The main problem is that it requires setting up sources for amd64 corresponding to the distribution you are running. This will differ fron distro to distro, and there are quite a lot of variants around.

There is definitely something wrong with my debian config, I'll have a look later, I'll mark it as broken for now.

I think this is a serious case of "Pi in the Sky" as it does not work, even with the "updated instructions". (English in quotes)

I think that

deb [arch=amd64] http://deb.debian.org/debian buster main

or maybe

deb [arch=amd64] http://deb.debian.org/debian buster main contrib

should be enough to work

I also found that adding [arch=arm64] after 'deb' to the existing repos cleans up a lot of the 'doesn't support architecture' warnings

Hmm,  I'll have a good look tomorrow, in the meantime can you try removing the second and third line and try again?

Ok, so your distro is based on debian buster.

I think you need to add the following lines to a new file, '/etc/apt/sources.list.d/debian-arm64.list':

deb [arch=amd64] http://deb.debian.org/debian buster main
# deb [arch=amd64] http://deb.debian.org/debian-security/ buster-security main
# deb [arch=amd64] http://deb.debian.org/debian buster-updates main

This will add the main debian repositories for buster to you system, but only for amd64 packages.
run 'apt update' after adding the file and try installing suld again.


For my own system, which is based on ubuntu focal, I've added the file '/etc/atp/sources.list.d/ubuntu-amd64.list' with the content:
deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ focal main
deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ focal-updates main
deb [arch=amd64] http://archive.ubuntu.com/ubuntu/ focal-security main

This is probably due to the fact that there is no repository configured for amd64 packages.

Can you post the content of '/etc/apt/sources.list' and all/any files in '/etc/apt/sources.list.d/'?

You will need to add a source for amd64 sources, matching the version of your os.
