As an addendum, I guess I will wait until the transition to Ubuntu 16.04 for my tablet before filing a bug report to calibre upstream. I wouldn't want the developer to spend time on a platform that is about to be deprecated.

I am a recovering geek who mistakenly thought biology would be my calling, and while stumbling through grad school, still found time to spend an inordinate amount of time learning about Linux, and open source software and hardware.

My first smartphone was a the FirefoxOS-powered ZTE Open C, and the second phone is my Nexus 5 which is currently running LineageOS. I have the M10 FHD which I am willing to use as a test device for the latest images.

I enjoy using the latest software and find reporting bugs and seeing them resolved to be a very rewarding experience.

Syncthing would be a welcomed addition indeed. Thanks for working on it.

This is what my options are for the SD Card:

I have gone through the options, and they do not work at present.

I've made a quick test connecting a Debian box to my Ubuntu phone and Calibre fails to write to the sd card. However I can write to the sd card using mtp directly (v.g. making a directory named "Books").

Yes, I have already mentioned that I can write to the SD Card directly. My problem is I cannot get calibre to do it through its interface.

But I do appreciate the assistance in this endeavour.

@advocatux This is my output from sudo mtp-detect

OK.

Forgive me for being a bit chuffed. I know what sudo calibre does. I also frequently employ chown as well. What I do not understand is the need to run calibre as sudo just to get file transfer working (if that will even work) when I can transfer files to my android and LineageOS devices without involing sudo. I would appreciate more detail on what the intention is before I execute the command.

@advocatux

1. I am running openSUSE Tumbleweed for my calibre library. There is no sudo mtp-detect command
2. Yes. It's on a 5 minute timer before auto-locking.
3. I am not running any program with sudo unless I am 100% certain I won't accidentally screw up assignments of files and folders. I learnt that years ago with "sudo firefox". Reassigning ownership for 2500 ebooks is something I am not keen on doing.

@advocatux Just to test it wasn't my external sd card, I tried to connect to a storage folder on the internal sd card. It doesn't work because it is an mtp connection, and it is apparent that calibre for now is not set up for mtp with the M10 FHD.

This is the error log when calibre detects the device:

If there is a way to expose the internal or external sd cards as USB storage instead of using the mtp protocol, calibre will work. That would be a concrete solution at present.

@advocatux The problem is I can't even navigate to the SD Card via calibre's folder connection settings. So I can't test your suggestions.

@mike It is very nice. Unfortunately, I can't find a cbz reader in the Open Store yet, no no comics for now I guess.

@doniks I will give it a shot, and see how it goes with upstream.

@doniks @advocatux

Sorry for the lack of clarity. calibre is a cross platform ebook manager. It has a feature that allows users to manage their ebook collection on various connected devices. It has a repository of recognised devices built-in so most ereaders like the Kobo or Kindle reader can be connected without hassle.

For unrecognised devices, it is possible to designate an ebook folder on a devices through calibre so that ebooks can be transferred and managed with ease.

I created an ebook folder on the MicroSD card because it is likely to take up a lot of space. Unfortunately, I cannot figure out a way to navigate to that directory from calibre as the connection uses the MTP protocol. So the address is mtp:/[path-to-folder], instead of /media or something equivalent.

I have many books that I would love to peruse on the BQ Aquaris, but unfortunately, I cannot navigate to the "Books" folder I created on my tablet through calibre to set up a manageable ebook repository, as it uses the MTP pr.otocol.

I have not been able to find a guide to connect calibre to that specific folder on my MicroSD Card, so I am wondering whether anyone in the community knows a way to do it.

My tablet is now running the community edition of Ubuntu.

Thanks!
