+# python3-gi is being installed as a dependency by 'openjdk-8-jdk'. python3-gi is not wanted since it installs PyGObject 3.48.2 (which we are not using),
+# This issue showed up when we pinned pygobject==3.50.0 in the chip-repl in https://github.com/project-chip/connectedhomeip/pull/37948
+# having pygobject ==3.50.0 being installed through pip creates a conflict, and pip can not unintstall the PyGObject (python3-gi's version) because the system APT installed it
+# Error log:
+#   ERROR: Cannot uninstall 'PyGObject'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
