I change the code to:
check_userns() {
userns_restricted=$(sysctl -e -n
kernel.apparmor_restrict_unprivileged_userns)
unconfined_userns=$([ -f
/sys/kernel/security/apparmor/features/policy/unconfined_restrictions/userns ]
&& cat
/sys/kernel/security/apparmor/features/policy/unconfined_restrictions/userns ||
echo "no")
if [ -n "$userns_restricted" ] && [ "$userns_restricted" -eq 1 ]; then
if [ "$unconfined_userns" = "no" ]; then
# userns restrictions rely on unconfined userns to be
supported
aa_action "disabling unprivileged userns restrictions
since unconfined userns is not supported / enabled" \
sysctl -w
kernel.apparmor_restrict_unprivileged_userns=0
fi
fi
}
And don't have more the message.

Title:
Installation of AppArmor on a 6.14 kernel produces error message
"Illegal number: yes"
Status in AppArmor:
Invalid
Status in apparmor package in Ubuntu:
Fix Released
Bug description:
Installing the AppArmor package on a Plucky machine that is running a
6.14 kernel produces the error message
"/var/lib/dpkg/info/apparmor.postinst: 148: [: Illegal number: yes".
This is due to an underlying kernel sysctl
(/sys/kernel/security/apparmor/features/policy/unconfined_restrictions/userns)
changing from a 0/1 integer (semantic boolean) to a "no"/"yes" string
in Ubuntu's 6.14 kernel, causing our debian/patches/ubuntu/userns-
runtime-disable.patch to fail because it expects a 0/1 integer. The
switch to "no"/"yes" will be needed if/when the sysctl is upstreamed.
As such, we should patch our debian/patches/ubuntu/userns-runtime-
disable.patch to be robust and handle both 0/1 and "no"/"yes" values
for the sysctl.
