在Ubuntu 20.04中运行podman时出现问题

Question

不同的问题，主要与用户名称空间的数量有关。

尝试运行预构建的映像会产生：

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)

所以我不能真正运行这个东西。然后试图运行一个本地构建的容器，它创建了一个我得到的用户：

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

已使用subuid设置配置

jmerelo:100000:65536

虽然

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

所以一定有什么东西我错过了，或者我应该在这里重新开始。即使我再次登录，结果还是一样。所以一定是我做错了什么。

同样的问题通过以下方式解决：

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