Flexo docker fails to start: "No such file or directory", then "Unable to fetch mirrors remotely"

[adrfantini]

I am trying to setup a Pacman package cache on my Unraid server using Flexo.

The docker run line is:

docker run -d --name='Flexo-arch-package-cache' --net='bridge'
  -e TZ="Europe/Berlin" -e HOST_OS="Unraid" -e 'PUID'='99' -e 'PGID'='100' \
  -e 'FLEXO_LISTEN_IP_ADDRESS'='0.0.0.0' \
  -e 'FLEXO_NUM_VERSIONS_RETAIN'='2' \
  -e 'FLEXO_MIRRORS_AUTO_ALLOWED_COUNTRIES'='IT,DE,FR,AT,SI' \
  -p '7878:7878/tcp' \
  -v '/mnt/user/appdata/flexo/pkg':'/var/cache/flexo/pkg':'rw' \
  --restart=on-failure:5 \
  'nroi/flexo:latest'

However, it crashes on start.

Logs:

Will try to fetch them from cache.

I noticed that /etc/flexo/ is empty, might that be the reason?

This looks like a bug that was already fixed, you probably ran into the issue with nroi/flexo:latest not being the latest version.

I've updated the docker image, please fetch the new image and let me know if this works for you.

I confirm that that was the issue, thank you!
