Problems running podman in Ubuntu 20.04

Different problems, mainly related to the amount of user namespaces.

Trying to run a pre-built image yields:

podman run --rm -it -p8080:8080 --env LOGSTASH_CONF_STRING=$LOGSTASH_CONF_STRING --name logstash bitnami/logstash:latest 
Completed short name "bitnami/logstash" with unqualified-search registries (origin: /etc/containers/registries.conf)
Trying to pull docker.io/bitnami/logstash:latest...

  Error processing tar file(exit status 1): potentially insufficient UIDs or GIDs available in user namespace (requested 0:4 for /var/log/apt/term.log): Check /etc/subuid and /etc/subgid: lchown /var/log/apt/term.log: invalid argument

Error: 2 errors occurred while pulling:

So I can't really run this thing. Then trying to run a locally built container which creates a user I get:

Error: OCI runtime error: container_linux.go:370: starting container process caused: setup user: invalid argument

Configuration has been set up with subuid

jmerelo:100000:65536

Although

podman unshare cat /proc/self/uid_map
0       1000          1

So there must be something that I'm missing or that I should restart here. Even if I log in again, it's still the same result. So there must be something that I'm doing wrong here.

Same problem solved by following this:

rm -rf ~/.config/containers ~/.local/share/containers
podman system migrate
