I'm migrating a Samba DC that uses Bind9, but when I try to start Bind on the new DC, a permission error is displayed. Reading some links I saw that the apparmor can be a problem, however it is not mounted. What should I do to solve this problem?

Software versions:

Debian: 11.6
Samba: 4.13.13
Bind: 9.16.33

Output journalctl -xe:

named[4664]: /etc/bind/named.conf:15: open: /samba/restore/bind-dns/named.conf: permission denied
named[4664]: loading configuration: permission denied
named[4664]: exiting (due to fatal error)

Output aa-status:

apparmor module is loaded.
apparmor filesystem is not mounted.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
