Hi, I'm trying to upgrade to Bullseye at the moment, but a bit stuck on which non-Debian packages I need to remove; root@hawaiian:~# apt-forktracer | sort | awk -F ' ' '{print $1}' containerd.io docker-ce docker-ce-cli docker-ce-rootless-extras docker-scan-plugin elasticsearch google-chrome-stable kibana libnvpair3linux libuutil3linux libzfs4linux libzpool4linux logstash spl-dkms zfs-dkms zfsutils-linux zfs-zed root@hawaiian:~# aptitude search '?narrow(?installed, ?not(?origin(Debian)))' i A containerd.io - An open and reliable container runtime
i docker-ce - Docker: the open-source application container engine i A docker-ce-cli - Docker CLI: the open-source application container engine i A docker-ce-rootless-extras - Rootless support for Docker. i A docker-scan-plugin - Docker scan cli plugin. i elasticsearch - Distributed RESTful search engine built for the cloud i google-chrome-stable - The web browser from Google i kibana - Explore and visualize your Elasticsearch data i logstash - An extensible logging pipeline spl-dkms These (libnvpair3linux, libuutil3linux, libzfs4linux, libzpool4linux, spl-dkms, zfs-dkms, zfsutils-linux, zfs-zed) are from Backports, so do they need to be removed? I ask as my /var is mounted as ZFS and that might get tricky! I can handle removing the docker ones as I'd like to install Podman anyway. Is there a proper way I should do this? Would I be taking a risk keeping elasticsearch, kibana, logstash and chrome or should I just remove those too? Should I comment out the entries in apt/sources.list.d? Thanks James
