Calibre 6 install Raspberry PI

lewisdale · 07-17-2022, 04:04 PM

I attempted an install of calibre 6 on a raspberry pi 4 2GB of ram. If failed. I ran a debu and it seems to not like many of my plugins that were installed with the previous 5.12.0 version through apt. The output of the debug script is below.

Any ideas what is going wrong here? I have checked the items shown on the Linux install page of the Calibre website and I seem to meet all requirements.

Due to calibre 6 moving to qt6 from qt5 many plugins needed to be updated. Before installing calibre 6 try updating plugins to current levels, or post installing calibre 6 update them.

Whatever version DeDRM you have needs to be updated to the current 10.0.3. That's the Calibre 6 compatible version.

gbm · 07-17-2022, 05:49 PM

See if calibre will start with plugins disabled, in a terminal type:

Code:

calibre --ignore-plugins

If it starts them go to preferences-plugins
then click Show only user installed plugin then disable DeDRM and Goodreads More Tags plugin's.

Then try to start calibre

Regardless of plugins, this:

ImportError: cannot import name 'QApplication' from 'qt.core'

seems like a dealbreaker. As does the missing libOpenGl error.

kovidgoyal · 07-18-2022, 01:05 AM

you are missing required system libraries see the notes on the calibre linux download page.

lewisdale · 07-18-2022, 09:50 AM

Debian bullseye is on QT5. that is my base problem. Oh well, i guess i just have to roll back to 5.13.0 for now.

Why not 5.44?

Entirely possible that 5.13 is the latest version in the repository for an ARM system?

gbm · 07-18-2022, 02:28 PM

Looks like the required system libraries are in the Debian bullseye despotically.

Hey all, I am also a bit confused by what I am supposed to do to install the new Calibre 6 on my raspberryPi. I see mentions of "the linux download page", but everything there takes me to intel references, nothing to do with ARM. I have tried using the "calibre-6.1.0-x86_64.txz" and the "calibre-6.1.0-arm64.txz" files and manual binary install and I get an error… "/opt/calibre/calibre_postinstall: 1: Syntax error: "(" unexpected" in both cases…

I tried using the binary install command (even though it mentions intel why not…) and again, fails…

So am I missing something? I can see people have got it to install, but how? Source install?

You will need to click on the Linux 32-bit binary link in the calibre 6.1.0 downloads page to download the calibre-6.1.0-arm64.txz file. An error in naming since there is no longer a 32 bit version of calibre. Perhaps the first line could be changed to read calibre x86-64 binary and the second line should read calibre arm64 binary.

After that, the manual install line from the Linux install page should work after editing to give the correct tarball name, etc.

I don't have an ARM64 Linux box to test on but the install.sh script looks as if all the needed ARM64 select code is in place for it to work if all the prerequisites are in place.

Check and make sure that your have libEGL installed.

ChrisChinchilla · 07-19-2022, 03:10 AM

Thanks! @DNSB that does look like a typo on the link indeed!

However, I still seem to get errors…

/opt/calibre/calibre_postinstall: 1: Syntax error: word unexpected (expecting ")")

If I cd into that directory and run directly

-bash: ./calibre_postinstall: cannot execute binary file: Exec format error

I took a look at the file info…

./calibre_postinstall: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, BuildID[sha1]=xxx, for GNU/Linux 3.7.0, stripped

I have a Rpi 400, 64-bit CPU… Hmm…

arch command results in "armv7l"

Here is where I am a bit in the deep end, I assume that should be compatible, but maybe not?

So it seems that Rpi 400 is 64-bit, but raspian is 32-bit, so the new binaries won't install… So I guess i need to try and re-install the older 3.9 version?
