Unable to Print.

BaronJ · 2019-06-21 18:36

Hi Guys,

I think a recent update has caused a problem with printing !

Everything was fine on Monday

Samsung_SCX-4200_Series gaffer 24 [17/Apr/2019:09:26:52 +0100] 1 1 - localhost Center slide End Plate.png - -

Then today trying to print anything just hangs. Doing "localhost:631" just returns "Waiting for localhost"
and "cupsdoprint" returns "No printers installed".

I've re-installed CUPS without success.

Thanks.

Best regards:
BaronJ.

Another problem ! I've just tried to install an update to python, and I get these error messages.
Also I note that there has not been any response to my previous post !!!

I can't help specifically with your problem, but have you checked your network is functioning properly?

I do not understand this :-

With the apt problem you could try running

sudo apt update

before trying to install anything in case the file has been updated on the server and so the old version can no longer be found which could cause this type of error.

EDIT:
I noticed the Debian (Q4OS) version of python3 is either 3.5.3-1 for Stretch (Scorpion) or 3.7.3-1 for Buster (Centaurus) so it seems you are trying to install a package that is not there.

EDIT2:
Sorry just noticed the Jessie tag in the file, Jessie (Orion) has version 3.4.2-2

Hi Dai_trying,

Thank you for your reply ! Yes I am running Q4OS Orion.

With regard to the print problem the message was from the last successful print done logfile.
Samsung_SCX-4200_Series gaffer 24 [17/Apr/2019:09:26:52 +0100] 1 1 - localhost Center slide End Plate.png
Which was a png image of some engineering work. I posted the whole line because it contains all the information about the printer, the time & date and what the file was. I still can't print anything !

Then today there was this update for "Python" and since then I cannot update anything. I copied and posted the error messages from the screen.

I'm now stuck ! Unable to print and unable to update anything. The red update icon keeps coming back and nothing updates, just the same error messages.

Thanks for your help getting this problem sorted, just tell me what I have to do.

BaronJ · 2019-06-25 19:03

I ran "sudo apt update" and this is what came back...

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

gaffer@castlelinux:~$ apt list --upgradable

Did you get any errors from the apt-update command, the Debian repositories have moved recently and I would have expected the output to show some errors...
Could you run apt update again and post the FULL output here. (Tip: if you use code blocks it will be easier to read)

q4osteam · 2019-06-25 21:06

You should remove the conflicting package first:
$ sudo dpkg -r --force-all python3.4
next fix apt system run:
$ sudo apt-get update
$ sudo apt-get install -f
Please post the complete output of all the commands.

BaronJ · 2019-06-26 09:23

Hi Guys,

I did "sudo dpkg -r --force-all python3.4" as requested

this is the output,

Gaffer@castlelinux:~$ sudo dpkg -r --force-all python3.4
dpkg: python3.4: dependency problems, but removing anyway as you requested:
python3-uno depends on python3.4.
python3 depends on python3.4 (>= 3.4.2-0).

That seems to have cleared bad python items and installed python 3.4 Ok.

Thank you for that, however I still can't print anything !
I still get "localhost contacted waiting for reply" when I try to print something

If I go and look at the error log I see "Max clients reached, holding new connections"
which makes no sense to me.

q4osteam · 2019-06-26 09:48

Now run:
$ sudo apt-get dist-upgrade
check if the output is ok, reboot and try printing again.

No ! I still get the "localhost contacted. waiting for reply" message.
If I go and look at the error log I see "W [26/Jun/2019:10:40:47 +0100] Max clients reached, holding new connections..."

BaronJ · 2019-06-26 11:43

Hi Guys,

Something has changed, after trying to print a pdf file this time.

From var/log/cups, Access log.
"localhost - - [26/Jun/2019:11:21:16 +0100] "POST /printers/Laser HTTP/1.1" 200 453 Create-Job successful-ok
localhost - - [26/Jun/2019:11:21:16 +0100] "POST /printers/Laser HTTP/1.1" 200 94681 Send-Document successful-ok"

and from var/cups, Error log.
"W [26/Jun/2019:11:29:29 +0100] Max clients reached, holding new connections..."

and from var/cups, page log. the same message, unchanged, as previously posted.
"Samsung_SCX-4200_Series gaffer 24 [17/Apr/2019:09:26:52 +0100] 1 1 - localhost Center slide End Plate.png - -"

However I still get the localhost contacted message, but after about 15 minutes the cups admin page appeared, clicking on "Printers" just hung.

Thanks guys.

Dai_trying · 2019-06-26 13:28

Have you tried restarting cup? I have not had to do it myself but the command should be

sudo service cups restart

I would hope this would kinda reset any current connections and at least allow you to start printing.

Also have you checked if there are any documents in the queue?

This Ubuntu link should give you some commands to get the information from the command line which might help as you cannot access the web interface.

BaronJ · 2019-06-27 09:36

Hi Guys,

I've managed to get a JPG to print ! The application seemed to have hung, but I had to go away and do something else for maybe an hour, when I came back the printer had produced a print of the picture that I had sent earlier.

I've tried all the suggestions made and followed several others without any success.

I don't understand the "Max clients reached, holding new connections" message and feel that Cups has some odd corruption.

What do I need to do to purge Cups and re install a clean version ?

Thanks Guys.

bin · 2019-06-27 10:58

It may be worth a look in /var/spool/cups - delete any jobs in there as root

Is this a wifi or USB connection? If wifi can you connect vis USB and see if that helps?

TBH I would suggest you look at a reinstall with a newer version as the underpinnings of Debian Jessie (Orion) are bit ancient.

Why not try Scorpion?

Personally I would go for Centaurus as it will be "Stable" very soon, but obviously it is a matter of preference.

BaronJ · 2019-09-28 11:02

Hi Guys,

Problem solved ! See below.

Commented out the second line ! Problem solved.
