This may be as simple as having language-pack-XX installed in the
|
||||
pre-install stage
|
||||
|
||||
* This element ensures /tmp/ccache will be available in the chroot
|
||||
during the root, extra-data, pre-install, install and post-install
|
||||
stages. /tmp/ccache is unavailable during block-device, finalise
|
||||
and cleanup stages as it will have been automatically unmounted
|
||||
by then.
