Snap Migration tool?

Greetings and Salutations,

Is there any way to convert apps that were installed as APT packages to snap packages automatically and if so is there any way to maximize the conversion so that all possible apps are migrated automatically?

Best, Acceptable

Trying another way:

Ubuntu with the fewest non-snap apps. Needs a lot more work but this is a rapid PoC

install ubuntu-live-server

sudo apt install --no-install-recommends task-lxqt-desktop

Tested on KVM/QEMU/libvirt/virt-manager so these are needed:

sudo apt install xserver-xorg-video-qxl spice-vdagent

Common packages

sudo apt install sddm-theme-debian-maui lxqt-themes xfwm4-theme-breeze oxygen-icon-theme

pipewire (sound), printers screensaver, etc. have not been installed.

On the panel (“taskbar”) at the bottom you can click on Qterminal.

Run lxqt-config from terminal. Change icon theme to Humanity. You might need to logout and in or reboot. The icons should be visible now.

The moment you’ve been waiting for

sudo snap install snap-store

Find some spot on the panel where you can right-click so that “Configure panel” is an option and select it.

Fiddle with the controls until the Application Menu (bird-like icon in the panel) is not covered up by anything.

Now you have the most minimal Ubuntu in the world, so almost no applications that are available as snaps are installed as deb packages via apt.

exceptions: Featherpad Qterminal

unfortunately there isn’t an automatic way to convert apt-installed apps to snap packages that covers all possible apps. each app need to be individually assessed and converted. it’s always a manual process as i know
