COPS server. Again. Sorry

Troubleshooting
#1

Hello,

A few months ago I followed this guide while installing COPS server on a Pi2 running DietPi OS v6.3. I didn’t have much of a clue what I was doing and was pleasantly surprised that it worked out OK.

I’m now trying to install COPS on to a Cubox-i running the latest DietPi. The Cubox’s DietPi delivered via the bash script which converted Armbian to DietPi v7.9.

As before, I’ll be putting the Calibre library on usb storage. With Syncthing copying the library from my PC to the Cubox. Syncthing is working fine. As is the ProFTP file server and all of DietPi’s settings and configurations. However, the same can’t be said for COPS. I followed the step-by-step instructions like last time but either I’ve made some stupid mistake (highly likely) or some changes to DietPi and Debian Bullseye have made the instructions unworkable.

Does anyone have an idea what’s gone wrong and how I could get my e-book library back?

I should mention that Ubooquity or Komga aren’t an option because they don’t play well with my e-reader’s web browser.

#2

well you could have started sharing some error messages you are facing. :wink:

On the other hand side, probably COPS is not working on Bullseye anymore. I see COPS has not been updated for 2.5 years. Probably it did not work probably with Bullseye libraries and/or actual PHP version? I see you already opened same question with COPS Github https://github.com/seblucas/cops/issues/509

#3

Sorry about the lack of info. It’s just that nothing happens. Not even an error report. And to be honest, aside from some report during the initial terminal work, I wouldn’t know where to look for error messages.

If COPS isn’t going to work do you have any idea how to install Calibre-web? I’ve tried following their instructions but each time I see a huge number of red errors during the install process. I also tried installing via Docker, but that didn’t work either.

If you can get Calibre-web working then it might be worth considering as an addition to DietPi? Ubooquity is discontinued and web access is too demanding for most e-readers. The alternative of Komga is great for comics but not for e-books. It sorts books by title. It doesn’t have an option to sort and present by author name; which can make it near impossible to find what you’re looking for in large e-book collection.

#4

what system your are running

Required Information

  • DietPi version | cat /boot/dietpi/.version
  • Distro version | echo $G_DISTRO_NAME $G_RASPBIAN
  • Kernel version | uname -a
  • SBC model | echo $G_HW_MODEL_NAME or (EG: RPi3)

bullseye

Linux DietPi 5.10.60-imx6 #21.08.1 SMP Wed Aug 25 19:08:13 UTC 2021 armv7l GNU/Linux

Generic Device (armv7l) or Cubox-i I2U-300D

#6

I don’t have such a device like you. Therefore I used a RPi3B+ running ARMv7 Bullseye and installation of calibreweb was running quite well as I could use pre-compiled wheels from piwheels.org

Success! Very happy. It’s a late Christmas present. Thank you so much for your help.

In the end it was really simple. I don’t know what I’d been doing wrong but I have a talent for overcomplicating the obvious.

From the little time I’ve spent with Calibre-web it does look like an ideal candidate for DietPi.

Just one thing is still puzzling me. How do I autostart the application? I had a look at these start-service instructions but I can’t find the calibre-web starter file for a pip installation.

A note for anyone considering using this with a Kobo e-reader’s web browser. I needed to change the calibre-web guest settings to allow anonymous browsing. I also found it worked better when I changed DietPi’s web server to Nginx.

CPS executable should be located at /usr/local/bin/cps

root@DietPi4:~# which cps
/usr/local/bin/cps
root@DietPi4:~#

Sorry to be a continuing bother but what am I doing wrong? The cps command works but the following doesn’t.

I added a cps.service file (below) to /etc/systemd/system. Then sudo systemctl enable cps.service. Lastly, sudo systemctl start cps.service

[Unit]
Description=Calibre-Web

[Service]
Type=simple
User=root
ExecStart=/usr/local/bin/cps

[Install]
WantedBy=multi-user.target

#10

can you share the log

systemctl restart cps
systemctl status cps
journalctl -u cps
#11

Well that’s unexpected. I entered the first line and all of a sudden it’s working now: reboot after reboot.

who knows. good it is working now.

Yes it is good. And thank you for your help. The sbc would otherwise be redundant. It was previously used for Volumio but unfortunately the device is no longer supported. Without your help it’d be destined for landfill or another paperweight. Either way it’d be a terrible waste.
