How start ubuntu-drivers & where are its help files?

Asked by markling

I was relieved to see Ubuntu software updater tell me it was installing something to manage drivers. Because I've been having scanner trouble. (System won't recognise the SCSI adapter. Can't find info on how to get it to work).

But after update, there's no driver option in the System menu of my GUI. Neither do there appear to be manual pages or help pages.

Have I got the wrong end of the stick? Is this not a user tool at all? SimpleScan still can't see my scanner.

Cheers.

None of the commands appear to work, fyi.

~$ ubuntu-drivers devices
~$ ubuntu-drivers list

~$ ubuntu-drivers autoinstall
No drivers found for automatic installation.

What is the output of:

lsb_release -a; uname -a; lsusb

How does the scanner connect to the system?
What make and model is tthe scanner?
Have you tried xsane?

Please excuse me, actionparsnip. I only became aware of your answer when the Launchpad janitor popped up in my inbox to say this question had expired. So many bugs, so little time.... :)

SCSI

Epson GT-7000

Have you tried xsane?

No, I haven't. I will try this. Thank you.

I presume I was correct about ubuntu-drivers? Nothing for a mere grovelling user to be concerned with?

Ubuntu-drivers is meant to offer you the choice in cases where there are two ore more different drivers for a specific piece of hardware (e.g. NVidia display cards with the possibility to use the opensource nouveau driver or the proprietary NVidia driver).
If there is a SCSI adapter you should expect that either the driver is installed automatically (without the need to call ubuntu-drivers), or such driver might be not available at all.

Do you see your SCSI adapter with the commands lspci respectively lsusb?

I had used xsane, actually, in addition to a variety of investigations of the scsi subsystem - perahps a useful reference to someone else:

lsscsi
cat /proc/scsi/scsi
lspci -k
lsmod | grep aic7xxx
cat /proc/modules

And some other stuff.

It is crucial to have the scanner switched on before booting the system. This had made no difference to me previously. The scanner simply wasn't being detected. There appeared to be a fundamental problem.

But after updates to systemd and udev this week - perhaps coincidentally, but most certainly without explanation - it now works.

Cheers for your help, Manfred, Parsnip.
