Description of problem: On restart. SELinux is preventing snapd from 'create' accesses on the file sections.F8S3X422g8L4. ***** Plugin catchall_labels (83.8 confidence) suggests ******************* If you want to allow snapd to have create access on the sections.F8S3X422g8L4 file Then you need to change the label on sections.F8S3X422g8L4 Do # semanage fcontext -a -t FILE_TYPE 'sections.F8S3X422g8L4' where FILE_TYPE is one of the following: dbusd_etc_t, snappy_home_t, snappy_var_lib_t, snappy_var_run_t, snappy_var_t, systemd_unit_file_t, tmp_t, udev_rules_t. Then execute: restorecon -v 'sections.F8S3X422g8L4' ***** Plugin catchall (17.1 confidence) suggests ************************** If you believe that snapd should be allowed create access on the sections.F8S3X422g8L4 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 'snapd' --raw | audit2allow -M my-snapd # semodule -X 300 -i my-snapd.pp Additional Information: Source Context system_u:system_r:snappy_t:s0 Target Context system_u:object_r:var_t:s0 Target Objects sections.F8S3X422g8L4 [ file ] Source snapd Source Path snapd Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-283.21.fc27.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.14.13-300.fc27.x86_64 #1 SMP Thu Jan 11 04:00:01 UTC 2018 x86_64 x86_64 Alert Count 3 First Seen 2018-01-17 17:23:31 PST Last Seen 2018-01-19 00:54:37 PST Local ID 858033dc-6a75-464a-917c-b3b5947d4e8f Raw Audit Messages type=AVC msg=audit(1516352077.377:254): avc: denied { create } for pid=2579 comm="snapd" name="sections.F8S3X422g8L4" scontext=system_u:system_r:snappy_t:s0 tcontext=system_u:object_r:var_t:s0 tclass=file permissive=1 Hash: snapd,snappy_t,var_t,file,create Version-Release number of selected component: selinux-policy-3.13.1-283.21.fc27.noarch Additional info: component: selinux-policy reporter: libreport-2.9.3 hashmarkername: setroubleshoot kernel: 4.14.13-300.fc27.x86_64 type: libreport
