Canon printer failed to connect with CUPS

[SunBear]

My canon printer has been working with Ubuntu 16.04 for quite sometime. Presently, for no reason, it now cannot be recognised. I have checked that the USB connections are working fine. When I unplug and replug the printer usb connection to my computer the syslog reflects it's present. However, it shows that it failed to connect with CUPS. udev-configure-printer[5761]: failed to connect to CUPS server; giving up I have provide the results to my printer checks below.

Appreciate help to reestablish the proper connection of my printer and get it working with Ubuntu 16.04.

Your syslog contains:

Feb 2 22:36:43 Eliot udev-configure-printer[5761]: failed to connect to CUPS server; giving up

and you also get

@Eliot:~$ lpinfo -v
lpinfo: Bad file descriptor

Seems that there is a problem with the CUPS daemon not starting.

Please run the command

ls -l /var/run/cups/cups.sock

and post the output here.

Also attach your files /etc/cups/cupsd.conf and /etc/cups/cups-files.conf.

Go to

https://wiki.ubuntu.com/DebuggingPrintingProblems

and follow the instructions of the "CUPS error_log" section.

Please attach the files one by one, do not compress them and do not package them together, thanks.

@Eliot:/media$ ls -l /var/run/cups/cups.sock
ls: cannot access '/var/run/cups/cups.sock': No such file or directory

However, I found

I have gone into https://wiki.ubuntu.com/DebuggingPrintingProblems and
tried to follow the instructions of the "CUPS error_log" section.

Step 1.
I can't do it. Can't find "Save debugging information for
troubleshooting" on "System" -> "Administration" -> "Printing". I have
System Setting --> Printers --> Help --> Troubleshoot --> Forward. I get
the message
CUPS Service Stopped
The CUPS print speel does not appear to be running. To correct this,
choose System-Administration-Services from main menu and look for 'cups'
service.
My difficulty is there isn't such a path to follow. The is no
Administration icon.

Step 2:
@Eliot:~$ cupsctl LogLevel=debug
cupsctl: Unable to connect to server: Bad file descriptor

Step 3:
Skipped - Not applicable.

Step4: I have gone into /etc/cups/cupsd.conf and manually uncommented
LogLevel....
Original:
# Deactivate CUPS' internal logrotating, as we provide a better one,
especially
# LogLevel debug2 gets usable now
MaxLogSize 0
Presently:
# Deactivate CUPS' internal logrotating, as we provide a better one,
especially
LogLevel debug2 gets usable now
MaxLogSize 0
@Eliot:~$ $ sudo /etc/init.d/cups restart
$: command not found
The file is there. I believe Ubuntu16.04 is using systemd. I tried this
and got the below failure message.
@Eliot:~$ sudo systemctl restart /etc/systemd/system/cups.service
Failed to restart etc-systemd-system-cups.service.mount: Unit
etc-systemd-system-cups.service.mount not found.

Unable to do Step 5,6, 7, 8.

After switching the connection of the printer in the printer properties, from USB type to using the printer DNNS, my Canon printer is able to print again. In the make and mode, it shows Canon MG5300 series - CUPS+Gutenprint v5.2.11. It is puzzling how cups is not able to detect my printer.

[SunBear (sunbear-c22)]

I found the answer. I checked "apt" history log in /var/log/apt and discovered that when I executed the "apt-get install ubuntu-desktop", the "ubuntu-desktop" package installed many cups packages (see below). These installations fixed whatever problems cups had previously. Wish someone could have just told me about this simple solution to fixing cups.
