Ho un’istanza di discourse in esecuzione su Ubuntu. Non ho effettuato l’accesso al sistema per un po’ e ha richiesto un aggiornamento con do-release-upgrade.
Sembra che funzioni correttamente, ma dopo il riavvio discourse non funzionava e facendo un systemct restart docker journalctl ha rivelato:

È davvero un problema con il kernel? Non sono sicuro di come procedere e, naturalmente, quando ho digitato do-release-upgrade non ho fatto un backup del database di discourse, ho pubblicato alcune note importanti recenti che vorrei recuperare
