Migration Yunohost 11.3.0.2 towards 12 / lacking space in /boot/

Hello @rodinux :wave:
While sudo cat /etc/apt/sources.list shows the following:

# deb cdrom:[Debian GNU/Linux 11 _Bullseye_ - Unofficial amd64 CD Binary-1 20220808-10:55]/ bullseye main non-free

#deb cdrom:[Debian GNU/Linux 11 _Bullseye_ - Unofficial amd64 CD Binary-1 20220808-10:55]/ bullseye main non-free

deb http://ftp.debian.org/debian bullseye main contrib
deb-src http://ftp.debian.org/debian bullseye main contrib

## YunoHost repository

The file /etc/apt/sources.list.d/yunohost.list does not exist.
Running sudo yunohost tools versions returns:

I presume this means the no changes were made by the migration? But tbh, I’m not really sure what does this all mean :confused: Should I run sudo update-grub then reboot then run uname -r or should I do something else? Thank you so much for taking the time, this is really kind of you!!
