When I try to run the command sudo apt-get install python2 python-gtk2 python-glade2 libgtk2.0-dev

it returns:

E: Unable to locate package python-gtk2
E: Unable to locate package python-glade2

Hi @joseraeiro,

I assume that you had successfully installed and ran Keepnote on a Ubuntu 20.04 LTS previously but after performing a clean 22.04 LTS installation, the said dependencies are now missing?

Discovered a workaround quite recently but would highly recommend implemeting it on a virtual machine or spare computer first before your daily driver.

Haven't explored other options to address the problem as of the time of this writing; succeeding posts from other users will likely provide a much better and cleaner approach. Discovered mine around the same time you posted your question, so please proceed with caution.

The workaround steps are as follows:

• Perform a clean 20.04 LTS installation
• After the 20.04 LTS reboots and you have logged in, it will prompt that a new LTS release is now available.
• DO NOT click the upgrade button just yet; click the Remind Me Later button instead.
• Install aforementioned dependencies and then install Keepnote
• Confirm that Keepnote is running by opening any previous backed-up / saved notebooks
• Perform a distro upgrade from 20.04 to 22.04 LTS (https://www.linuxtechi.com/upgrade-ubuntu-20-04-to-ubuntu-22-04/)

The entire process will take a bit longer compared to the clean installation but this (for now) will get the Keepnote running on the latest 22.04 LTS.

Successully implemented the workaround on a Xubuntu 22.04 LTS.

Hope this helps.
