WIP: Install Ultimaker Cura on ChromeOS v71 with Crostini (Linux apps) container support
View gist:3842663d784f97c767d6ce57c1b2e41e
# Trevor Sullivan
# I want to install Ultimaker Cura on ChromeOS, under the Crostini container environment.
# Cura is distributed officially as the Linux AppImage format, not a Debian package.
# Crostini doesn't support AppImage as of December 2018, due to dependency on FUSE, which isn't supported.
# Crostini is compatible with Debian packages.
# There is an Ubuntu Personal Package Archive (PPA) with Debian packages for Cura.
# However, Crostini starts as a Debian Stretch environment.
# The Cura package is only available for Debian Buster.
