This still happens on Fedora 27: selinux-policy-3.13.1-283.26.fc27.noarch BackupPC-4.1.5-1.fc27.x86_64 Chris, Any idea why BackupPC runs under httpd_t domains? Lukas I have no idea. I just raised the issue in July 2017. Apparently, it still happens, but I have not had the problem now for some months. So could I close it? Lukas Perhaps you should ask Joel Uckelman whether he still has the issue. Yes, this still occurs:
SELinux is preventing BackupPC_Admin from write access on the file LOCK.
***** Plugin catchall (100. confidence) suggests **************************
If you believe that BackupPC_Admin should be allowed write access on the LOCK 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 'BackupPC_Admin' --raw | audit2allow -M my-BackupPCAdmin
# semodule -X 300 -i my-BackupPCAdmin.pp
