I think this issue is still present for me.
Turris Omnia with TOS 5.4.4
Both repositories for comparison.
https://us.lxd.images.canonical.com/meta/1.0/
https://repo.turris.cz/lxc/meta/1.0/
Turris repository does not have “index-user”
root@turris:~# lxc-create -l debug -t download -n ubuntu
Setting up the GPG keyring
Downloading the image index
ERROR: Failed to download http://repo.turris.cz/lxc//meta/1.0/index-user
lxc-create: Ubuntu: lxccontainer.c: create_run_template: 1617 Failed to create container from template
lxc-create: Ubuntu: tools/lxc_create.c: main: 327 Failed to create container Ubuntu
LXC fails in Luci too, Luci can load the OS list, but container won’t install.
Is anyone else having this issue?
