W: Failure trying to run: chroot "/home/phablet/.cache/libertine-container/firefoxcontainer/rootfs" dpkg --force-depends --install /var/cache/apt/archives/libc6_2.31-0ubuntu9_arm64.deb
W: See /home/phablet/.cache/libertine-container/firefoxcontainer/rootfs/debootstrap/debootstrap.log for details (possibly the package /var/cache/apt/archives/libc6_2.31-0ubuntu9_arm64.deb is at fault)
ChrootContainer.py:94: ERROR: create_libertine_container():     Failed to create container
libertine-container-manager:126: ERROR: create():       Failed to create container: 'destroy_libertine_container() missing 1 required positional argument: 'force''

It can be reproduced by just simply creating a new container with the Terminal or with the System Settings.

Still an issue 14.07.2025. Can be forced to work by doing this https://forums.ubports.com/post/73301.
