create example not working

[DeathsGun]

I tried running the create/create example and got the following output:

lxc 20220324161237.959 ERROR    conf - conf.c:userns_exec_mapped_root:4499 - No uid mapping for container root
lxc 20220324161237.959 ERROR    lxccontainer - lxccontainer.c:do_storage_create:1292 - Error chowning "/home/lbue/.local/share/lxc/rubik/rootfs" to container root

lxc 20220324161237.959 ERROR    lxccontainer - lxccontainer.c:do_lxcapi_create:1871 - Failed to create dir storage for rubik

Even tough i have set up the uid mapping in ~/.config/lxc/default.conf: cat ~/.config/lxc/default.conf

lxc.include = /etc/lxc/default.conf
lxc.idmap = u 0 100000 65536
lxc.idmap = g 0 100000 65536

When using lxc-create -t download test then it will create the container like expected.

First of all, you need to make sure your user has a uid and gid map defined in /etc/subuid and /etc/subgid. On Ubuntu systems, a default allocation of 65536 uids and gids is given to every new user on the system, so you should already have one. If not, you'll have to use usermod to give yourself one.

e.g.

 usermod -v 1000000-1065535  jaro
