When I try to install the app engine plugin from the Eclipse marketplace, the installation fails returning:
An error occurred while collecting items to be installed
session context was:(profile=_home_user_eclipse_jee-2021-063_eclipse, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

Environment: Ubuntu 18.04.6 Eclipse IDE for Enterprise Java and Web Developers 2021-06 (4.20.0) Google Cloud Tools for Eclipse 1.8.4 Java JDK 8
Any hint?
Thanks in advance, Sebas
Already tried using the "help-install new software" option. Same result with ubuntu 20 or JDK 11. I tried to find previous plugin versions with no result.
