[lxc-users] Error updating certificates when a directory is bind mounted

[Luis Michael Ibarra]

Hi everyone,

I got the following error when I tried to install a package(via apt) which
requires to install/update its certificates on a lxd container which it has
a host directory bind mounted.

$lxc config device add $container data disk
source=/path/to/external_usb_disk path=/tmp/


------------------------------------------------------
$apt-get install git

......
Setting up ca-certificates (20160104ubuntu0.12.04.1)

--------------------------------------------------------------------------------------------------

I can successfully install git when the device is not mounted; however, I
do need to have it mounted because is a large drive which I need for my
operations.

Any suggestions why this is happening.
