Migration Yunohost 11.0.10.2 buster to bullseye impossible

The logs you posted are showing that this is an Ubuntu machine with Firefox installed … So I doubt that this was on your server x_x

Do you want to continue? [Y/n] 
Get:1 http://security.ubuntu.com/ubuntu focal-security/main amd64 firefox amd64 106.0.5+build1-0ubuntu0.20.04.1 [59.5 MB]
[...]

Edit:

and also sudo: yunohost: Befehl nicht gefunden which indicates yunohost is not installed (on that machine) i suppose

But i´m sure to have setup a VPS with ISO from Yunohost. As i said 2 Days ago the script from you installed firefox… dont know why…

Hi there,

it looks that I’m stuck in the same situation with a failing migration and a subsequent update :anguished: .

Thanks @Aleks for sharing the script, but unfortunately it didn’t work:

nb:
I have also opened an issue with logs on my failing migration:
