Comment 5 for bug 2036966

I have given this another go with the newest edge version of the ubuntu-budgie-installer snap. Booted with the Ubuntu Budgie beta iso (20230920).

Opened a terminal and performed a snap refresh:
ubuntu-budgie@ubuntu-budgie:~$ snap refresh ubuntu-budgie-installer --channel edge
ubuntu-budgie-installer (edge) 0+git.a38f4ea from Ubuntu budgie (ubuntubudgie) refreshed

Double-checked version with: snap list
ubuntu-budgie-installer 0+git.a38f4ea 28 latest/edge ubuntubudgie classic

Repeated the same steps, checking the box for installing the support for additional media formats.

I ran into the same installation failed message as before, with the message:
system install failed for ['ubuntu-restricted-addons']: Unexpected error when running the command

Attached are the new logs / .crash file
