Note

  • "-nv" means non-verbose output
  • "-O-" means output to stdout. It is the same as "-O -". See what is -O- option means for wget? The dash "-" means standard input or standard output (this case). See here or Download and Un-tar(Extract) in One Step.
  • As we can see from the screen message when we run the command again, it (linux-installer.sh) will not download the file again. In fact the file is saved under /tmp/calibre-installer-cache/.
$ ls -lth /tmp/calibre-installer-cache/
total 60M
-rw-r--r-- 1 root root 60M Jul 21 10:35 calibre-3.46.0-x86_64.txz
-rw-r--r-- 1 root root 128 Jul 21 10:35 calibre-3.46.0-x86_64.txz.signature
  • when we include sudo -v at the beginning, it will prompt us to enter the sudo password immediately. However, if we don't have sudo -v at the beginning, the prompt stays at a strange location when it is asking the sudo password.

Error on Ubuntu 20.04.1

$ calibre
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

Aborted (core dumped)

Calibre 5.0.1 Could not load the Qt platform plugin "xcb" FIXED. After I installed just one missing component libxcb-xinerama0, then it works.

Fetch News and recipes

Some RSS feeds

Builtin feeds that do not work

  • US and World Report news
  • Wired Magazine (monthly ed)
  • Discover Magazine

The recipes files (*.recipe) and the <index.json> file are saved in $HOME/.config/calibre/custom_recipes. They can be loaded through 'Add custom news source' dialog. So backing up the ~/'Calibre Library' does not include the custom recipes.

Tips

  • Calibre will show the file size for each title/recipe. If the title is too large, send to kindle may not work (>40MB not work but 27MB works)
  • If we have multiple files to send, it will wait 301 seconds before sending for the 2nd one, to avoid being marked as spam. You can control this delay via Preferences->Tweaks
  • Each recipe has two parameters: oldest article (how many days) and max # of articles per feed (default is 100). Since all recipes are scheduled to download every day, I can set 1 day for the oldest article.

A commercial service Keendly does it for a fee.

Autostart Calibre after a reboot

Two steps:

  1. Automatic login desktop
  2. Autostart a program after logging into your desktop

Remove a schedule download

Check the checkbox 'Schedule for download' at the top of source.

Some news source

Command line

ebook-convert ~/.config/calibre/custom_recipes/(your recipe) test.epub --test -v -v

ebook-convert myrecipe.recipe test.epub --test -vv

Troublshooting

  • Install a copy of Calibre on my local computer. Import the recipe files downloaded from the remote server.
  • Enable VNC on the remote server. Or run Calibre on my local computer.

Reabble

Delete mails from gmail

It seems the mails sent through gmail to kindle took space. To reclaim the space in gmail,

  • Go to one.google.com/storage to confirm the current space used by gmail
  • Go to gmail. Search 'calibre'. Select all checkbox. Select all XXX conversations. Delete
  • Go to gmail -> Trash. Select all checkbox. Select all XXX conversations in Trash. Delete forever.
  • Go to one.google.com/storage to confirm the current space used by gmail

ebook format

  • pobi: this is a Kindle Store Magazine Ebook Format when Calibre generated and sent is to my Kindle. POBI is a variation of MOBI and enables the display of articles and sections in periodical content. NOTE: If you change the POBI extension to MOBI then the Sections & Articles index of the magazine will not appear.
  • azw3: this is the format for the books I purchase from Amazon, or using the browser extension to send it to my kindle

Calibre Ebook Server for transferring files/read on browser

  • Read it on browser: Left/right swipe on a single article. Up/down swipe to change articles. However, the control is not responsive. No way to go back. Downloading the files and use the mobile apps to read files is probably better.
  • Preferences - Behavior - uncheck 'Automatically send downloaded news to e-book reader'. Preferences - Sharing - Sharing books by email - uncheck "Auto send"
  • My workflow is choose "epub" as the output format. On My Android e-ink device, I use a browser to download files via the Calibre-server web service. Finally I'll open the epub file by Moon+ Reader.
  • We can start calibre-server automatically when the desktop is launched. Preferences - Sharing over the net - Main - check Run server automatically when calibre starts
  • Docker

Moon+ Reader

  • How to connect to my Calibre OPDS server?
  • Using Moon+ Reader is better than FF browser b/c for some reason FF cannot refresh the Calibre web server page.
  • On Onyx eReader, after I select a book, Left=Download, Right=Open.
  • Options - Main Folder. If I try to modify it, the screen will show the current folder (Left=Cancerl, Right=OK).
    • /sdcard/Download on Onyx Note Air. It's actually /sdcard/Download/MoonReader. But on Onyx, it does not show files with folder structures. So all files are listed there.
    • /sdcard/Books on phone. It's actually /sdcard/Books/MoonReader/.
