Similar problem has been detected: This happens on every boot. I do not have secureboot enabled, so I'm unsure what is going on. But I am using efi. hashmarkername: setroubleshoot kernel: 5.6.8-300.fc32.x86_64 package: selinux-policy-targeted-3.14.5-32.fc32.noarch reason: SELinux is preventing systemd-tty-ask from 'read' accesses on the file SecureBoot-8be4df61-93ca-11d2-aa0d-00e098032b8c. type: libreport I've submitted a Fedora PR to address the issue: https://github.com/fedora-selinux/selinux-policy/pull/364 commit 9f5cfe46706e04a45960a8c98c08f9d2c637abaa

Introduce systemd_read_efivarfs_type attribute
Introduce systemd_read_efivarfs_type attribute for domains to read efivarfs.
Create a systemd_read_efivarfs() interface to allow a domain be part of
the systemd_read_efivarfs_type attribute.
Replace fs_read_efivarfs_files() calls in systemd.te
with systemd_read_efivarfs().

Description of problem: SELinux is preventing systemd-tty-ask from 'read' accesses on the file SecureBoot-8be4df61-93ca-11d2-aa0d-00e098032b8c. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that systemd-tty-ask should be allowed read access on the SecureBoot-8be4df61-93ca-11d2-aa0d-00e098032b8c file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # ausearch -c 'systemd-tty-ask' --raw | audit2allow -M my-systemdttyask # semodule -X 300 -i my-systemdttyask.pp Additional Information: Source Context system_u:system_r:systemd_passwd_agent_t:s0 Target Context system_u:object_r:efivarfs_t:s0 Target Objects SecureBoot-8be4df61-93ca-11d2-aa0d-00e098032b8c [ file ] Source systemd-tty-ask Source Path systemd-tty-ask Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-3.14.5-32.fc32.noarch Local Policy RPM selinux-policy-targeted-3.14.5-32.fc32.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 5.6.8-300.fc32.x86_64 #1 SMP Wed Apr 29 19:01:34 UTC 2020 x86_64 x86_64 Alert Count 1 First Seen 2020-05-01 13:08:48 CEST Last Seen 2020-05-01 13:08:48 CEST Local ID 05abfe4f-5e14-4232-a7e5-7f1be0af6a69 Raw Audit Messages type=AVC msg=audit(1588331328.189:208): avc: denied { read } for pid=1906 comm="systemd-tty-ask" name="SecureBoot-8be4df61-93ca-11d2-aa0d-00e098032b8c" dev="efivarfs" ino=12847 scontext=system_u:system_r:systemd_passwd_agent_t:s0 tcontext=system_u:object_r:efivarfs_t:s0 tclass=file permissive=0 Hash: systemd-tty-ask,systemd_passwd_agent_t,efivarfs_t,file,read Version-Release number of selected component: selinux-policy-targeted-3.14.5-32.fc32.noarch Additional info: component: selinux-policy reporter: libreport-2.12.0 hashmarkername: setroubleshoot kernel: 5.6.8-300.fc32.x86_64 type: libreport
