Unable to install Modelio Open SOurce 4.1 on Ubuntu 20.04

Steps I follow: I have downloaded the software from Modelio's website. Open the terminal. cd to Downloads ls to list Download's content sudo dpkg -i and the software's name

I get this: dpkg: error processing package modelio-open-source4.1 (--install): dependency problems - leaving unconfigured

I also have tried in the GUI area by using Ubuntu's Software and I get:

Unable to install modelio-open-source4.1: The following packages have unmet dependencies

How to solve that ?

THANKS IN ADVANCE !!

Solution 1:

You have to download the dependencies from 18.04 LTS repository and install them with ModelIO package on 20.04 LTS using APT by using commands below:

cd ~/Downloads # use correct folder here where ModelIO deb is stored
wget -c http://archive.ubuntu.com/ubuntu/pool/universe/w/webkitgtk/libwebkitgtk-1.0-0_2.4.11-3ubuntu3_amd64.deb
wget -c http://archive.ubuntu.com/ubuntu/pool/universe/w/webkitgtk/libjavascriptcoregtk-1.0-0_2.4.11-3ubuntu3_amd64.deb
wget -c http://security.ubuntu.com/ubuntu/pool/main/i/icu/libicu60_60.2-3ubuntu3.1_amd64.deb

sudo apt-get install ./libwebkitgtk-1.0-0_2.4.11-3ubuntu3_amd64.deb ./libjavascriptcoregtk-1.0-0_2.4.11-3ubuntu3_amd64.deb ./libicu60_60.2-3ubuntu3.1_amd64.deb

sudo apt-get install ./modelio-open-source_4.1.0_ubuntu_amd64.deb

Solution 2:

As of 30/01/2022 for Ubuntu 20.04 the library

libicu60_60.2-3ubuntu3.1_amd64.deb

isn't available anymore and it's replaced by

libicu60_60.2-3ubuntu3.2_amd64.deb

should be used. So the reponse should now be

wget -c http://archive.ubuntu.com/ubuntu/pool/universe/w/webkitgtk/libwebkitgtk-1.0-0_2.4.11-3ubuntu3_amd64.deb
wget -c http://archive.ubuntu.com/ubuntu/pool/universe/w/webkitgtk/libjavascriptcoregtk-1.0-0_2.4.11-3ubuntu3_amd64.deb
wget -c http://security.ubuntu.com/ubuntu/pool/main/i/icu/libicu60_60.2-3ubuntu3.2_amd64.deb
    
sudo apt-get install ./libwebkitgtk-1.0-0_2.4.11-3ubuntu3_amd64.deb ./libjavascriptcoregtk-1.0-0_2.4.11-3ubuntu3_amd64.deb ./libicu60_60.2-3ubuntu3.2_amd64.deb

It works on my machine.
