Getting this issue in Android kernel.

How to fix this issue. Is there anyone who can help.

Looks like SELinux issue. Either put your SELinux in permissive mode (e.g. via kernel cmdline), or create corresponding SELinux rule. Take a look here for details. – Patch

yeah to edit SELinux rules tried these methods ----- allow untrusted_app device:chr_file { read write }; allow untrusted_app prn0:chr_file { read write }; added these lines in untruste app.te file but none of these worked – Ossieossietzky

Similar with Docker: audit:. type=1400 audit: apparmor=“DENIED” operation=“ptrace” profile=“docker-default”. – Paulettapaulette

Hey, have you find any solution about this? To do that do you have to root the android device? – Aryn

I get this same issue, have you fixed it? – Squama
