Could not install on Ubuntu 24.04 (derivative)

[pbrada]

I wanted to install Modelio 5.4.1 on Linux Mint 22, but install (using the modelio-open-source-5.4.1_amd64.deb) fails with

This package is uninstallable
Dependency is not satisfiable: libwebkit2gtk-4.0-37 (>= 2.24)|libwebkitgtk-3.0-0 (<= 2.4.11-3)

probably because the installed version is libwebkit2gtk-4.1-0.

The system is a Lenovo notebook with i5-8250U and 8GM RAM.
Kernel: 6.8.0-48-generic arch: x86_64 bits: 64 Desktop: Xfce v: 4.18.1 Distro: Linux Mint 22 Wilma

As the release notes for v5.1.0 state: The libwebkitgtk-3.0-0 library is mandatory for Modelio but it's no longer available in the official repositories for later versions of Ubuntu.

The following procedure has to be applied :
sudo nano /etc/apt/sources.list

Add the following line and save:
deb http://fr.archive.ubuntu.com/ubuntu bionic main universe

sudo apt-get update
sudo apt-get install libwebkitgtk-3.0-0

These steps are copied from the release notes of v5.1.0:
https://github.com/ModelioOpenSource/Modelio/releases/tag/v5.1.0

On Linux Mint you can do the same using Software Sources app and navigating to Additional Repositories.

Thanks for pointing me there, I clearly overlooked the info.

However, I don´t think I want to go this direction, except maybe only in a containerized install: https://www.cvedetails.com/vulnerability-list/vendor_id-11350/product_id-20596/Webkitgtk-Webkitgtk.html ...

If someone on Ubuntu 24.04 is having an issue with adding the source

deb http://fr.archive.ubuntu.com/ubuntu bionic main universe

with an error such as The following signatures couldn't be verified because the public key is not available
You must identify the key, e.g 3B4FE6ACC0B21F32, and then add the key signature :

sudo gpg --keyserver keyserver.ubuntu.com --recv-keys 3B4FE6ACC0B21F32
sudo gpg --export --armor 3B4FE6ACC0B21F32 | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/3B4FE6ACC0B21F32.gpg

My workaround on Ubuntu 24.04, without modifying your apt source is to download those debian files :

• https://debian.pkgs.org/12/debian-main-amd64/libwebkit2gtk-4.0-37_2.46.0-2~deb12u1_amd64.deb.html
• https://debian.pkgs.org/12/debian-main-amd64/libjavascriptcoregtk-4.0-18_2.46.0-2~deb12u1_amd64.deb.html
• https://debian.pkgs.org/12/debian-main-amd64/libicu72_72.1-3_amd64.deb.html
• https://debian.pkgs.org/12/debian-main-amd64/libavif15_0.11.1-1_amd64.deb.html
• https://debian.pkgs.org/12/debian-main-amd64/libdav1d6_1.0.0-2+deb12u1_amd64.deb.html
• https://debian.pkgs.org/12/debian-main-amd64/libsvtav1enc1_1.4.1+dfsg-1_amd64.deb.html
• https://debian.pkgs.org/12/debian-main-amd64/libjpeg62-turbo_2.1.5-2_amd64.deb.html

Then you should install them with sudo apt install ./{}.deb in backward order.

After that you should download the modelio deb file :

• https://github.com/ModelioOpenSource/Modelio/releases/tag/v5.4.1

And finally doing sudo apt install ./{modelio}.deb should work

@Hennzau Thanks, that did the trick :) I still have it installed in a virtual machine, not on the main computer, due to security concerns.
