#242022 — Problem with Synaptic

[Multipart message — attachments visible in raw view] — view raw

I am running buster on my Linux platform.

I have installed a new Brother Laser print using the current Brother 
Linux installer.

The printer is working, but when I try running Synaptic I get an 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.

I tried Goggling but didn't find any solutions. Then I tried 
uninstalling the offending package and got an error:

comp@AbNormal:~/Downloads/Brother-MFC-L2710DW$ sudo ./uninstaller_brscan4
[sudo] password for comp:
dpkg: error processing package brscan4 (--purge):
  package is in a very bad inconsistent state; you should
  reinstall it before attempting a removal
Errors were encountered while processing:
  brscan4

That failed. Finally,  I tried reinstalling with dpkg, which also 
failed. The complete log is attached.

At this point I am completely beyond my depth in even starting to 
understand the error messages, let alone solving it.

Help will be much appreciated.

Thanks in advance.

Perhaps consider updating to Bullseye (Debian 11) as the latest stable

If this is the Brother installer from Brother - a commercial product - we
probably can't help. Take it up with Brother? How did you download it - from
where - and how did you install it

That suggest that this wasn't a Debian package recognised by packaging
databases, maybe.

Not properly installed: you might 

apt-get --fix-install

If the worst is the worst, 

dpkg --configure -a 

might help. The last resort is forcibly deleting bits of package and manually
amending the package database which is somthing you _really_ don't want to do
unless absolutely unavoidable.

Manually delete all files under /opt/brother/scanner/* and try again?

Hope this helps in some smwall way at least. With every good wish, as ever,

I appreciate your answer.

However, manually deleting

/opt/brother/scanner/* and reinstalling gave me the same results.

The MFC-L2710DW is a modern device and is completely supported by
packages shipped with Debian 11 (bullseye). It is also completely
supported for printing via a wireless connection on buster.

The packages needed for USB connections and scanning do not come
with buster but can easily be obtained from

  https://github.com/alexpevzner/sane-airscan

Do yourself a favour and read

  https://wiki.debian.org/CUPSQuickPrintQueues

A user with a device such as yours does not need proprietary,
non-free printing or scanning drivers in 2021.

Interesting indeed. Reaching for printing and scanning drivers,
whether free or non-free, is still a user's first thought. I
suppose one should work to tackle the issue you outline but
switching to driverless printing and scanning is a lot easier
and makes most problems involving drivers go away. Additionally,
it future-proofs the printing and scanning systems.

As much as I want to move on to Debian-11.1, I am limited by the fact 
that some of the software that I need for my Computational Chemistry 
research is not at the point where I can successful compile it Debian-11.

Right now I can't run Synaptic or apt tokeep my present installation 
running the way I want. It's imperative that I solve the current problem

Try downloading it again (since it's not part of the archives, it must 
be downloaded manually) and running 'apt install ./brscan4-......deb' 
(substituting the actual file name, naturally). The './' is necessary to 
tell apt it's a file name.

I appreciate your reply.

Here is what happened:

Yeah, that didn't work.

You might try copying the .deb file to /var/cache/apt/archives and then 
trying something like 'apt -f install' to see if it picks the file.

If not, this like has some possible solutions: 
https://askubuntu.com/questions/88371/apt-synaptic-needs-to-reinstall-package-but-cant-find-the-archive-for-it 
(for another package, conincidentally also printer related). They seem 
to involve making apt/dpkg forget completely about the package. Backups 
are important here. (Well, they always are, but in this case they're 
even more important.)

If it works you can then try reinstalling it or going the "driverless" 
option.

No, to be precise, it tells the file system its a file in the currently 
cd'd to directory.  Which may not be in the env's $PATH.

It's both, Gene.

To the file system (kernel), ./foo is a relative pathname that's 100%
equivalent to foo.  There's no difference at all.

However, to apt-get or apt, ./foo and foo are very different arguments.
The former is a relative path to a file, and the latter is a package name.

This has nothing to do with $PATH, because we're not talking about running
a program from the current directory.  We're talking about apt-get and apt
specifically.

You're thinking of the conventional use of "./configure" and so on to run
a program in the current directory.  This is necessary because PATH should
never contain "." (or the empty string) as one of its components.  That
would allow the execution of *anything* at all in the current directory
(the way MS-DOS works).  This is a huge security problem on a multi-user
system, where someone could leave a script in /tmp hoping for you to
run it accidentally.

It *works* because the shell bypasses the PATH search if the command that
you give it contains a slash character.  ./configure means "run the program
named configure in the current directory, and don't search anywhere else".

Thanks Greg, a better view than mine.

This is the immediate problem that I need to fix:

comp@AbNormal:~$ sudo apt upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: The package brscan4 needs to be reinstalled, but I can't find an 
archive for it.

sudo apt update ran without any problems.

Thats b'cuz the Brother installer puts all that stuff in /opt, and for 
the most part I havn't touched it in around 3 years. It has some tcp crc 
hiccups early on, but thats gone away a long time ago and for a cheap 
B&W brother lazer, and a huge MFC-J6920DW, it Just Works. And synaptic 
has not ever asked for my attention by fussing about it.

Cheers, Gene Heskett.

Did this command then complete and give a prompt?

Did the output say how many packages needed to be upgraded?

Can you scan?

sudo apt update ran and:

2 packages can be upgraded. Run 'apt list --upgradable' to see them.

Sudo apt upgrade asked for a prompt and then spat out:

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: The package brscan4 needs to be reinstalled, but I can't find an 
archive for it.

Very satisfying.

BTW, in my first post I was was not urging you to upgrade to bullseye
but presenting the facts concerning printing and scanning on buster
bullseye. Should you wish to free yourself from the non-free Brother
drivers the choice is yours.
