We'll want that sudo fix included in Ubuntu.
It's the usual catch with unprivileged containers only being able to
lower their limits and never raise them so there's nothing we can really
do about it in LXD.

Title:
"sudo: setrlimit(RLIMIT_CORE): Operation not permitted" error when
using sudo in 20.04 LXD container
Status in lxd package in Ubuntu:
Invalid
Status in sudo package in Ubuntu:
Confirmed
Bug description:
I fired up a LXD container using ubuntu-daily:f on my machine and
every time I issue a comment inside the container using sudo, I get
this error:
sudo: setrlimit(RLIMIT_CORE): Operation not permitted
I did some digging online and found this was reported against Fedora last
fall which lead me to this bugzilla report:
https://bugzilla.redhat.com/show_bug.cgi?id=1773148
which seems to tie this to a change in sudo between 1.8.28 and 1.8.29.
Focal has 1.8.31:
bladernr@focal-builder:~/development/kernels-ubuntu/focal$ apt-cache policy
sudo
sudo:
Installed: 1.8.31-1ubuntu1
Candidate: 1.8.31-1ubuntu1
Version table:
*** 1.8.31-1ubuntu1 500
500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages
100 /var/lib/dpkg/status
This is not an issue on Bionic:
bladernr@galactica:~/development/kernels-upstream/mainline$ apt-cache policy
sudo
sudo:
Installed: 1.8.21p2-3ubuntu1.2
Candidate: 1.8.21p2-3ubuntu1.2

From the redhat bug, the described workaround does clear these
messages up:
# set disable_coredump false
Once I've done that, the error messages go away.
