Description of problem: On Fedora 27, after the last software update of yesterday, Spotify (under snapd) stopped working. When I start spotify from the terminal, I receive this error: cannot create tmpfs target /tmp/snap.rootfs_Gc6HQN/var/lib/snapd/lib/vulkan: No such file or directory I tried to snap remove spotify , and then snap install spotify. When the install runs, a lot of SElinux errors are thrown, including the one of this bug report. This was not happening with the previous version of snapd. SELinux is preventing snap-discard-ns from read, write access on the file spotify.lock. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that snap-discard-ns should be allowed read write access on the spotify.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 'snap-discard-ns' --raw | audit2allow -M my-snapdiscardns # semodule -X 300 -i my-snapdiscardns.pp Additional Information: Source Context system_u:system_r:snappy_t:s0 Target Context unconfined_u:object_r:var_run_t:s0 Target Objects spotify.lock [ file ] Source snap-discard-ns Source Path snap-discard-ns 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 Permissive Host Name (removed) Platform Linux (removed) 4.14.14-300.fc27.x86_64 #1 SMP Fri Jan 19 13:19:54 UTC 2018 x86_64 x86_64 Alert Count 1 First Seen 2018-01-31 23:05:17 CET Last Seen 2018-01-31 23:05:17 CET Local ID 576f2c68-f09b-428d-91c4-a2de490f611a Raw Audit Messages type=AVC msg=audit(1517436317.34:425): avc: denied { read write } for pid=21768 comm="snap-discard-ns" name="spotify.lock" dev="tmpfs" ino=126399 scontext=system_u:system_r:snappy_t:s0 tcontext=unconfined_u:object_r:var_run_t:s0 tclass=file permissive=1 Hash: snap-discard-ns,snappy_t,var_run_t,file,read,write 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: 4.14.14-300.fc27.x86_64 type: libreport
