No, su Linux o Ubuntu in generale è sempre stato cosi, dove non c'è un tool che fa tutto in automatico (Ubuntu lo ha da molti anni), ti basta editare il codename dei repository, ad esempio su Debian devi farlo manualmente, tranne che metti codename fissi, tipo: sid, stable, testing.

Non uso PPA e trovo tutto., dove non c'è una versione aggiornata di Ubuntu o non c'è proprio una versione, vado di flathub, anzi, preferisco per i software usare flatpak e flathub, se non disponibile li vado dai repository.
Di simile per ext4 non c'è nulla, perché è una funzionalità del filesystem, inoltre Btrfs ti garantisce l'integrità dei dati, cosa che non fa ext4.
Comunque, se vuoi rimanere con il filesystem ext4 (sarcasticamente lo nomino "filesystem dei poveri" :-D nel senso che non ha funzionalità ed è un filesystem ormai vecchio) puoi usare sempre Timeshif in modalità Rsync, occupa lo spazio = allo snapshot che devi fare, è lento, ma questo al primo backup, poi copia la differenza, almeno dovrebbe fare cosi.

Anzi, due PPA li uso:
(Steam, Chrome e MegaSync aggiungono in automatico i loro repo, quindi non sono PPA):
Codice:
emanu@desktop:~$ ls /etc/apt/sources.list.d/
alexlarsson-ubuntu-flatpak-focal.list cubic-wizard-ubuntu-release-focal.list google-chrome.list megasync.list steam.list
alexlarsson-ubuntu-flatpak-focal.list.save cubic-wizard-ubuntu-release-focal.list.save google-chrome.list.save megasync.list.save steam.list.save
Questi sono le APP flatpak:
Codice:
emanu@desktop:~$ flatpak list --app
