[R] R library highcharter function highchart() execute with exception the apparmor read denied for /etc/passwd and /etc/group

[Gu, Jay]

Dears,


I use the R library highcharter with ubuntu 18.04 and R 3.6.3. Recently, I upgraded to ubuntu 20.04 and R 4.3.1. And the version of library highcharter are both 0.9.4. Then I execute the function highchart() it always throw the exception that child process has died. And I checked the /var/log/kern.log and found below error:

Aug 7 08:37:50 ip-172-31-27-249 kernel: [2251703.494866] audit: type=1400 audit(1691397470.399:739): apparmor="DENIED" operation="open" profile="managedr-profile" name="/etc/passwd" pid=159930 comm="R" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0

If I add below two lines in my apparmor profile it will resolve this issue. But I don't like to expose these two files to end user as it has potential risk.
/etc/passwd r,
/etc/group r,

I'd like to know if there is any solution to fix it without giving the read access for these two files /etc/passwd and /etc/group in the apparmor profile as I did with ubuntu 18.04 and R 3.6.3. Thanks!
Best Regards!
