Nomacs

Good afternoon, I have tried to install nomacs through the terminal or with Synaptic but the application does not appear. How do I install it?

Re: Nomacs

Trying running Nomacs from the terminal, is there any output?

Hmmm but at

https://nomacs.org/docs/getting-started/installation/

I see:

Ubuntu and Linux Mint
nomacs is available in the “universe” repository of Ubuntu. Just install it using your favorite package manager. Translations can be added with sudo apt-get install nomacs-l10n. Install the heif plugin to load heif images.

Debian/Fedora
nomacs is included in the official repositories.

Arch Linux
nomacs is available as an AUR package.

{etc etc}

Not in Bookworm, Yes in Trixie.

p.s. Seems to build on Bookworm as well (Did a quick test on headless machine).
p.s.2. It does build and opens a window and can open an image and the grayscale filter is working (Didn't test any further).
