downgrade - What are non-latest Eclipse Oomph repository addresses?

Question

Latest Eclipse is experiencing this critical issue with GTK: https://bugs.eclipse.org/bugs/show_bug.cgi?id=568859

And I want to downgrade it. But the Oomph repository contains only the latest address and will not allow me to downgrade through the Help > About > Installation Details > Installations History > Revert.

Where can I find Oomph 1.18.0.v20200701 for example? Maybe even some earlier version, 1.17 will definitely work.

(ignore the fonts, it's GTK/KDE issue on Wayland)

Answer 1

The update site Oomph Latest Milestone points to the latest milestone or release which was the first milestone of Oomph 1.18 (1.18.0-M1) at the time you did the installation to which you now want to revert. But now it points to the Oomph 1.19 release. So everything of Oomph 1.18.0-M1 cannot be found anymore.

Adding the following update site should allow reverting to the installation you want to:
