Good, to know, thank you. Just to make it clear: I still think that the second alternative to hide the suggestion that a log file is created from the user, because it's unintuitive and imo possible, no matter which part of the program (core or dependency) generates it, but I assume that your comment and status change already had that in mind, so I won't bother more than adding this comment. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1671990 Title: failing lxc-create doesn't create log file mentioned in error message Status in lxc package in Ubuntu: Invalid Bug description: Example run: > sudo lxc-create -n debian-9-armhf -t debian -- --arch=armhf --release=sid debootstrap is /usr/sbin/debootstrap Checking cache download in /var/cache/lxc/debian/rootfs-sid-armhf ...
