Scusate in anticipo per la mancanza di alcuni dettagli… mi sono davvero cacciato in un guaio qui…
Se conoscete bene i requisiti delle autorizzazioni dei file in /var/discourse/shared/standalone, potreste saltare direttamente alla fine di questo post per la domanda principale e ignorare i dettagli che mi hanno portato qui 
L’ultimo aggiornamento basato sul web ha rotto la mia installazione - penso sia stato simile a Error Updating from 3.4.0.beta3-dev to 3.4.0.beta3, ma credo di essere stato sulla versione 3.4.0.beta4-dev
Sono anche su Ubuntu 20, quindi ora ./launcher rebuild app restituisce l’errore:
ERRORE: La versione di Docker 19.03.13 non è supportata, si prega di aggiornare almeno alla 20.10.0, o consigliata 24.0.7
Non credo che sia possibile, quindi ho creato un nuovo server e seguito i passaggi in Move a Discourse site to another VPS with rsync con il comando aggiuntivo per trasferire anche i volumi dal mio vecchio server:
rsync -rvz root@104.236.77.249:/var/lib/docker/volumes/ /var/lib/docker/volumes
Ora, sul nuovo server Ubuntu 24, ./launcher rebuild app restituisce questo errore:
Arresto del server di database PostgreSQL 15: main Errore: La directory dei dati /shared/postgres_data non deve essere di proprietà di root … fallito!

La cartella /var/discourse/shared è di proprietà di root sia sul vecchio che sul nuovo server. Scavando un po’ più a fondo, però, noto che c’erano alcune differenze nelle autorizzazioni in alcune cartelle di /var/discourse/shared/standalone…
Vecchio server:
/var/discourse/shared/standalone# ls -alh

drwxr-xr-x 14 root root 4.0K Jan 22 2021 .

Nuovo server:

drwxr-xr-x 3 root root 4.0K Feb 5 01:59 ..

drwxr-xr-x 4 root root 4.0K Feb 5 02:04 tmp
drwxr-xr-x 4 root root 4.0K Feb 5 02:04 uploads
Quindi ho cambiato la proprietà di due di esse sul nuovo server:
chown -R syslog: postgres_data
chown -R syslog: postgres_backup
Questo ha cambiato il messaggio di errore in qualcosa con cui non so cosa fare:
Arresto del server di database PostgreSQL 15: main Errore: Il proprietario della configurazione (postgres:101) e il proprietario dei dati (messagebus:102) non corrispondono, e il proprietario della configurazione non è root … fallito!
Per chiarire, le mie autorizzazioni attuali sul nuovo server sono:
/var/discourse/shared/standalone# ls -alh
total 60K
drwxr-xr-x 15 root root 4.0K Feb 5 15:32 .

Suppongo che qualche chown risolverà il problema per me, ma non so cosa/perché/come…
