Hi Seth, Thank you for the advice of "-i". It works if I append "-i" into the problematic line. It's strange that: 1) I can not see any difference between /home/ubuntu/test.sh, / opt/test.sh, /etc/test.sh and /usr/bin/test.sh, as there is no separated partition lsblk vda 252:0020G 0 disk ├─vda1 252:10 19.9G 0 part / ├─vda14 252:14 0 4M 0 part └─vda15 252:15 0 106M 0 part /boot/efi 2) Focal can not reproduce the issue.

[Touch-packages] [Bug 2020838] Re: [regression][jammy] augenrules Error sending add rule data request (No such file or directory)
Comparing the files /etc/systemd/system/multi-user.target.wants/auditd.service between Focal and Jammy, I can see Jammy has the line "ProtectHome=true", If I remove this line and reboot the system, then the rule can be loaded along with system bootup -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to audit in Ubuntu. https://bugs.launchpad.net/bugs/2020838 Title: [regression][jammy] augenrules Error sending add rule data request (No such file or directory) Status in audit package in Ubuntu: New Bug description: The rule '-a always,exit -F path=/home/ubuntu/test.sh -F perm=x -F auid>=1000 -F auid!=unset -k privileged' can not be loaded during system boot up. # lsb_release -rc Release: 22.04 Codename: jammy # dpkg -l|grep audit ii auditd 1:3.0.7-1build1 amd64User space tools for security auditing ii libaudit-common 1:3.0.7-1build1 all Dynamic library for security auditing - common files ii libaudit1:amd64 1:3.0.7-1build1 amd64Dynamic library for security auditing ii libauparse0:amd64 1:3.0.7-1build1 amd64Dynamic library for parsing security auditing # cat /etc/audit/rules.d/audit.rules|grep -v ^#|grep -v ^$ -D -a always,exit -F path=/home/ubuntu/test.sh -F perm=x -F auid>=1000 -F auid!=unset -k privileged -a always,exit -F arch=b32 -S mount -F auid>=1000 -F auid!=unset -k mounts -b 8192 --backlog_wait_time 6 -f 1 # ls -l /home/ubuntu/test.sh -rwxr-xr-x 1 root ubuntu 19 May 25 14:19 /home/ubuntu/test.sh # cat /home/ubuntu/test.sh #!/bin/bash echo 1 # >/etc/audit/audit.rules reboot the system, no rule can be loaded # auditctl -l No rules syslog: May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: Error sending add rule data request (No such file or directory) May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: There was an error in line 5 of /etc/audit/audit.rules May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: No rules May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: enabled 1 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: failure 1 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: pid 476 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: rate_limit 0 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: backlog_limit 8192 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: lost 0 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: backlog 0 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: backlog_wait_time 15000 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: backlog_wait_time_actual 0 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: enabled 1 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: failure 1 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: pid 476 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: rate_limit 0 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: backlog_limit 8192 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: lost 0 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: backlog 0 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: backlog_wait_time 15000 May 26 02:17:36 juju-d929ae-con28-1 augenrules[507]: backlog_wait_time_actual 0 # cat /etc/audit/audit.rules ## This file is automatically generated from /etc/audit/rules.d -D -b 8192 -f 1 -a always,exit -F path=/home/ubuntu/test.sh -F perm=x -F auid>=1000 -F auid!=unset -k privileged -a always,exit -F arch=b32 -S mount -F auid>=1000 -F auid!=unset -k mounts --backlog_wait_time 6 But I can manually load the rule file.

Additionally, I have ruled out AppArmor as a factor. I have already disabled the AppArmor service and append "apparmor=0" into the kernel command line before rebooting. Moreover, I can NOT reproduce this issue on Focal(1:2.8.5-2ubuntu6) There are 2 issues here,
