Wokay that’s … weird …
Let’s look at what python versions are installed:
```auto
dpkg --list | grep python
```

Hmokay so it’s still running python 3.7 instead of python 3.9 …
So let’s look at `apt policy python3`
And maybe let’s try `apt install python3.9 --dry-run`

Wokay I’m heavily confused
Can we check `dpkg --list | grep yunohost`
But I think the main issue is that you do not have any “proper” Debian repository in the apt’s configuration … This is probably related to what we discussed earlier, but it sounds like you removed too many lines …

Not exactly, but we can recreated the file according to what’s in the log you shared earlier … it sounds like you deleted the `/etc/apt/sources.list` file entirely but it was not problematic … (though indeed i advised to `grep ovh.net` without realizing the the problematic line were more specific, sorry for this)
So let’s recreate the file using `sudo nano /etc/apt/sources.list`
and add this content in it :
```nohighlight
deb http://debian.mirrors.ovh.net/debian bullseye main
deb http://security.debian.org/debian-security bullseye-security main
deb http://debian.mirrors.ovh.net/debian bullseye-updates main
```
Save with Ctrl+X, Y and Enter
Then
`apt update`
to refresh the apt cache
then uuuugh ideally if you can, you should re-run the Buster-\>Bullseye migration if Yunohost allows you to (using `yunohost tools migration run --accept-disclaimer` (maybe an ‘s’ at migration ? I always forget…))
If this complains that the “Distribution is not Buster”, then we shall retrigger the apt upgrade ourselves with this huge command:
```auto
DEBIAN_FRONTEND=noninteractive APT_LISTCHANGES_FRONTEND=none apt-get --fix-broken --show-upgraded --quiet -o=Dpkg::Use-Pty=0 -o Dpkg::Options::="--force-confold" -o Dpkg::Options::="--force-confmiss" -o Dpkg::Options::="--force-confdef" dist-upgrade
```
