Problema con babel italian in TeXworks con TeXLive Ubuntu 20.04 [Risolto]

Non so se è corretto quello che ho fatto, però funziona.
Sono andato su
`
https://launchpad.net/~texworks/+archive/ubuntu/stable
`

ho seguito le istruzioni dando i comandi
`
sudo add-apt-repository ppa:texworks/stable
sudo apt-get update
`

Dopodiché ho reinstallato TeXworks e ho riprovato con il file di prima e tutto funziona.
Questo è quando è scritto nel .log

Penso sia okay
La versione è aggiornata e non ho problemi con babel.
E non vedo più nessun’altra installazione oltre a quella di CTAN.
