Hello:

So ...
It's a bug in the grub installer?

Hello:

Haven't come across this but ...

I don't think there's any magic or wonder of any sort going on here.

The fact that lsusb does not show the connected device only means that.
ie: that it does not show/detect it.

But it does not mean that the SP Flash Tool cannot read the processor information belonging to the Android device.
ie: after all, it is the SP Flash Tool app that is doing the reading.

The thing is that (from what you are saying) the only place the SP Flash Tool can check the processor data is on the Android device.
And the only way the SP Flash Tool can do that is through the USB connection you established by plugging in the device.

That is, unless I am missing some new and recently develped tech.

Hello:

You should check that then.

Yes, install with the --no-install-recommends flag.

eg:

apt install --no-install-recommends [package_name_here]

See https://superuser.com/questions/615565/ … recommends for how to make that permanent in apt.

Hello:

Run this in a terminal:

~$ aptitude why libcups3

I run Devuan Beowulf with a backported kernel:

~$ uname -a

I have cups installed:

~$ apt list | grep installed | grep -i cups

But the library you referr to is not installed in my system:

~$ apt list | grep installed | grep -i libcups3
---
~$ 

~$ aptitude why libcups3
E: No package named "libcups3" exists.
~$ 

Maybe it is just a chimaera thing?

Hello:

Glad you were able to work it out.

I see that there are only 36 open issues at the CUPS GitHub page and only 3 have not been looked at/sorted/classified yet.
The last 2 being from this month and one from less than a month ago.

Not bad at all, I've seen much worse.
eg: LibreOffice, XFCE and others.

Hopefully you'll get a request for more information or feedback of some sort within a fortnight.
Please keep us posted.

Best,

A.

Hello:

Hmm ...

You may want to have a read here and here.
ie: Enter BIOS during power on (before Windows loads)

The first page is for the first L14 series (type 20U1, 20U2) and the second is for the following L14 series (type 20U5, 20U6) ThinkPads.
The BIOS seem to be the same.

I don't have one of those laptops so I really cannot say, but it seems to me that you may not be accessing the whole of the BIOS settings.

A.

Hello:

Hmm ...
No.

It's

For fuck's sake why?

Seriously, just who comes up with these dumb ideas?

which is one of the smartest and most useful Linux commands.

Hello:

That is because the system knows you have admin rights and as such, you not subject to the time restraint.
But for the rest of us, the 30s timer is always on, logged in or not.

Hello:

From what I see, issues have to be reported to the CUPS project issues page.

For starters you have to log-in and to do that you have to sign up/join/register with GitHub.

Once you get that (needed) administrative crap out of the way, you log-in and open a new issue.

As you may gather, given the complexity of the problem, the instructions for filing an issue must be followed to the letter.

ie: Like when you file a bug with Debian, in the hope it may be looked at eventually.

Note:
I recall that an HP Colour Laser printer I used 20+ years ago had to be calibrated every so often or when one of the (absurdly expensive) toner deposits had to be replaced, otherwise everything was off colour wise, more than the usual.

This Brother printer has something like that? Never seen one so I don't have a clue.

Hello:

Two out of four?  8^D

Probably (no idea) and no never (experience talking).

Which is why there's a whole industry dedicated to extract money from those who need to use standard/universally accepted profiles.
ie: that will allow printed/displayed pages to look/be seen as being the same, everywhere. 

I'm glad you think so.

In any case, it seems that there is no shortage of people attempting to bowl the same sticky wicket, so to speak.
From the little I have read on the matter, it has been, is and will continue to be so till something breaks.

As a result, there are quite a few apparently viable (?) alternatives, albeit with widely varying degrees of success, as usual.

Check https://www.color.org/opensource.xalter and https://www.color.org/creatingprofiles.xalter

Something's got to give.

Like I mentioned, I suspect that not only they know but that it is the default option for your printer.

You may want to spend some time looking through the Brother catalogue for a model which could meet the following criteria:

1. it is more expensive
2. it has more options
3. uses a similar ink/cartdrige/printing system
4. repeatedly uses the term professional in the User's manual.   8^D

If you don't find a suitable one, check to see if you can find out which brands are really Brother units with another label and look among them.
Maybe some printer repair shop or DIY page on the web has that data.

If and when you find it, get the ICC file and see how it works with your printer. 

Best,

A.
