I was working on Ubooquity as recently as last night, so no, not dead yet. ;)

Hello,

in the warning popu, the sentence "A full rescan of your comics will be done" is wrong and should have been "A full rescan of your books will be done".

But it does clean the books database, not the comics one.

Note that if you have not unchecked the "Scan collection at launch" option in the general settings, Ubooquity will launch a new scan as soon as the database is cleaned (as the server is automatically restarted afterwards).

No it does not. You are safe. :)

RAR is a proprietary format for which very few decompression library exist.

The library used by Ubooquity (the only existing in Java) has issues with some RAR file, and can't open RAR 5 files at all.

For comics there is no reason whatsoever to prefer RAR to Zip (cbz) anyway.

Calibre does not automatically writes to files the modifications you make.

Did you follow this procedure ?

Hello Elouan,

unfortunately not. I've been able to make some progress recently, but I will probably have to put development on hold for a few months.

The only thing I can tell is that I have not given up.

The feature is not available in the current version.

But it's already implemented in my working version, so it'll be part of the next release.

That's because this is not the right URL (you need to access /admin).

Just follow the documentation I linked in my first message, everything's in it.

Default admin port is 2203, not 2003.

Did you try with the --headless parameter ? (reference)

Your error makes me think you don't have a graphical environement, so you need to tell Ubooquity not to try to instantiate a GUI.
