Dear forum members,
after i updated mailcow yesterday and made an apt upgrade i got an apparmor issue. Nothing else has been changed but now the docker container will not start and mailcow does not work. Does anybody has an idea what i could do ?
when i try to start mailcow then there is this error:
Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: unable to apply apparmor profile: apparmor failed to apply profile: write /proc/self/attr/apparmor/exec: no such file or directory: unknown
when i look at dmesg then the error is a little bit more specific:
[ 1783.978306] audit: type=1400 audit(1676220492.693:66): apparmor=“DENIED” operation=“change_onexec” info=“label not found” error=-2 profile=“unconfined” name=“docker-default” pid=20961 comm=“runc:[2:INIT]”
how to solve this ?
apparmor and apparmor-utils are installed.
Thanks in advance for any idea :-)
