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"

profile="managedr-profile" name="/etc/group" pid=159930 comm="R"

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!
