[deldesir]

Fixes SyntaxError mentioned in #187.

Not tested yet. @nzola can you give this PR a try?

[holta]

@EMG70 would you have time to try this PR?

On any RPi 4 or RPi 400, if so!

I tested after running PR#201 script, box/books and 192.168.0.79/books both returned 502 Bad Gateway

Today I learned. Thanks @EMG70. I see what's happening. Next commit will remove the problematic f-string.

• Smoke-tested on Ubuntu 24.04
• PR will now be merged
• Needs additional testing after it's merged: can @nzola or @EMG70 fully retest (either fresh install or upgrade on Raspberry Pi!) in the coming 24h ideally?!

[EMG70]

I can now access box/books after upgrading.
There is however an xklb warning at the very top of upgrade script.Please see screenshot.

I personally can't reproduce @EMG70's failure of pipx to install xklb on "Raspberry Pi OS with desktop" — based on Debian 12 "Bookworm" — this all works for me:

sudo -i
apt install pipx
pipx install xklb    # Took about 3-4 minutes

.local/bin/lb --version
.local/pipx/venvs/xklb/bin/yt-dlp --version          # Run this on RasPiOS 12, Debian 12
.local/share/pipx/venvs/xklb/bin/yt-dlp --version    # Run this on recent versions of Ubuntu, and more modern OS's?
pipx upgrade --include-injected xklb

@EMG70 can you try the above commands on a completely fresh / untouched install of Raspberry Pi OS ("Lite" version or "with desktop" version) ?

@EMG70 looks much better:

Try the "Download to IIAB" button, and let us know how it works!?

Incredible news, thank you @EMG70 !

@deldesir Just to confirm, YES! Calibre-Web is working on both Pi4 and Pi400. Video downloads are working as well without any problems. BIG thank you! @deldesir

Thanks a lot @nzola for your feedback. This is good news though continuous battle-testing with different playlists/channels is needed.
