Unable to install bookworm in Ubuntu 20.04

[bhattisatish]

I tried following the installation instruction but I am running into some dependency issues.

the sudo apt install com.github.babluboy.bookworm gives me the following error

The following packages have unmet dependencies:
com.github.babluboy.bookworm : Depends: ninja but it is not installable
E: Unable to correct problems, you have held broken packages.

I cannot currently find any package named ninja in the Ubuntu repositories. Also why do we need a dev dependency on an installation of stable branch?

I too had similar issues , meanwhile you can try foliate or edr.thorium.

Same problem. On Pop OS here. The only instruction that worked was the flatpak.

[babluboy]

Could you try:

sudo apt-get install ninja-build
sudo ninja install

and then try com.github.babluboy.bookworm

You can also try the ppa method:

sudo add-apt-repository ppa:elementary-os/stable
sudo apt-get update
sudo apt-get install com.github.babluboy.bookworm

In case of issues related to missing libgranite package, add the Elementary PPA as shown below and re-try. The Elementary PPA can be removed after Bookworm is installed.

Some additional distro specific instructions are here: https://babluboy.github.io/bookworm/#install

[bhattisatish]

sudo apt-get install ninja-build sudo ninja install

Why is a build tool marked as a dependency for the package? Shouldn't this be a dependency in the source package?

Some additional distro specific instructions are here: https://babluboy.github.io/bookworm/#install

The dependency error comes up while following the Ubuntu installation instructions.

I tried installing ninja build tool as well, but the problem still resists. I've migrated back to Calibre, since it's essentially the same source code from bookworm. But the thing is, as of the latest version 4.22.0 there is no longer a toolbar on the left side of UI. However you could easily rollback to a previous version of Calibre, using the following sudo -v && sudo calibre-uninstall && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin version=3.48.0 I know it's not a solution, I, myself miss the old bookworm so much, and not fond of the extra features of Calibre(since I want to keep my workbench clean and minimal). I'm starting to think that upgrading to ubuntu 20.04 (considering its disastrous desktop) from 18.04 was a big mistake.

Workaround Using Flatpak

I was able to install it using Flatpak.

Flatpak Install

Once Flatpak is installed: flatpak install --from https://flathub.org/repo/appstream/com.github.babluboy.bookworm.flatpakref

@KaNaHaKEsUh That isn't a fix - it assumes you want to use flatpak.

The problem is with apt.

[ConradQQ]

@lonix1 is there a more appropriate place to post a workaround for users just trying to use Bookworm on Ubuntu 20.04? Because this thread was a top search result... Or are you just being a pretentious ass ?

[lonix1]

@KaNaHaKEsUh Your original comment, before you changed it, said "FIX", not "workaround".

I don't recall insulting you. Your rude behavior says it all.

Workaround Using Flatpak I was able to install it using Flatpak. Flatpak Install Once Flatpak is installed:

In Ubuntu 20.04, I installed Flatpak via Synaptic and then installed Bookworm as suggested

flatpak install --from https://flathub.org/repo/appstream/com.github.babluboy.bookworm.flatpakref

I had to restart my system before Bookworm would show up on my desktop but it is there now; so, thanks.

For Ubuntu there is a workaround:

You can get binary deb-package from Ubuntu 16.04 LTS directly by

cd ~/Downloads
wget http://archive.ubuntu.com/ubuntu/pool/universe/n/ninja/ninja_0.1.3-2_amd64.deb
sudo apt-get install ./ninja_0.1.3-2_amd64.deb

and install Bookworm from the PPA.
