Hello Forum:

 

I have to be missing something simple.  I'm running Debian 9.x.x and can do anything but PRINT!  I was downloading ppd, driver files for my HP Officejet 3830 so I could use the scanner.  Somehow I really screwed Cups.  Unit cups.service has failed on startup.  I can start the service and connect via ssh, but when I try to connect (other than ssh) I get service not available.

 

So now I'm in fuckit mode.  I want to delete everything related to cups and start over.  Any ideas how to remove everything that is CUPS?  I do have backups so I can format and reinstall, but that would take a day or so to reinstall and re configure

That's way too vague for us to figure out. You'll have to go through the steps you took one by one and post exactly what errors you get and when. If you want to start from scratch it should be enough to uninstall the packages and delete the configuration files you modified.


...is there a question here? 🤔

Sauron'stm Product Scores:

Spoiler

Just a list of my personal scores for some products, in no particular order, with brief comments. I just got the idea to do them so they aren't many for now :)

Don't take these as complete reviews or final truths - they are just my personal impressions on products I may or may not have used, summed up in a couple of sentences and a rough score. All scores take into account the unit's price and time of release, heavily so, therefore don't expect absolute performance to be reflected here.

 

-Lenovo Thinkpad X220 - [8/10]

Spoiler

A durable and reliable machine that is relatively lightweight, has all the hardware it needs to never feel sluggish and has a great IPS matte screen. Downsides are mostly due to its age, most notably the screen resolution of 1366x768 and usb 2.0 ports.

 

-Apple Macbook (2015) - [Garbage -/10]

Spoiler

From my perspective, this product has no redeeming factors given its price and the competition. It is underpowered, overpriced, impractical due to its single port and is made redundant even by Apple's own iPad pro line.

 

-OnePlus X - [7/10]

Spoiler

A good phone for the price. It does everything I (and most people) need without being sluggish and has no particularly bad flaws. The lack of recent software updates and relatively barebones feature kit (most notably the lack of 5GHz wifi, biometric sensors and backlight for the capacitive buttons) prevent it from being exceptional.

 

-Microsoft Surface Book 2 - [Garbage - -/10]

Spoiler

Overpriced and rushed, offers nothing notable compared to the competition, doesn't come with an adequate charger despite the premium price. Worse than the Macbook for not even offering the small plus sides of having macOS. Buy a Razer Blade if you want high performance in a (relatively) light package.

 

-Intel Core i7 2600/k - [9/10]

Spoiler

Quite possibly Intel's best product launch ever. It had all the bleeding edge features of the time, it came with a very significant performance improvement over its predecessor and it had a soldered heatspreader, allowing for efficient cooling and great overclocking. Even the "locked" version could be overclocked through the multiplier within (quite reasonable) limits.

 

-Apple iPad Pro - [5/10]

Spoiler

A pretty good product, sunk by its price (plus the extra cost of the physical keyboard and the pencil). Buy it if you don't mind the Apple tax and are looking for a very light office machine with an excellent digitizer. Particularly good for rich students. Bad for cheap tinkerers like myself.

You probably need to start CUPS and one sure way to check if the service is started is via your browser: navigate to http://localhost:631 and see if you get a login prompt or a webpage. If not, start CUPS. (I dunno ennitin about effin systemd, which is the init system Debian now uses and I detest fervently, so others might be able to help here)

This is the really wired part.  I can start CUPS, see it listening on 127.0.0.1:631.  (netstat) But browser(s) all say connection refused. (But I can connect via ssh) I did remove CUPS using apt-get remove --purge.  Then installed.  add-apt-repository ppa:hplip-isv/ppa > apt-get update >  apt-get install hplip with no errors.  The HPLIP package includes the latest CUPS version.

 

Still nothing.  There are no proxy settings in any of the browsers I used.  Logs still say CUPS SCHEDULER failed to start (on reboot)  As far as I can tell I can manually start all the CUPS Services, but still no connection.  (except seeing the port listening via netstat and connecting via ssh) My only thought is that apt-get remove --purge didn't get everything.  I think I know all file names and locations for CUPS - obviously I don't

For those who might care:

 

FMG I finally figured it out.  /etc/apt/sources.list.d/ had corrupt files (I didn't do it - musta been a computer thing - j/k)

I deleted the corrupt files, did an apt-update and reinstalled cups.

 

All better now.
