### 4) Rootless: could not get runtime - database configuration mismatch
In Podman release 0.11.1, a default path for rootless containers was changed,
potentially causing rootless Podman to be unable to function. The new default
path is not a problem for new installations, but existing installations will
need to work around it with the following fix.
#### Symptom
```console
$ podman info
could not get runtime: database run root /run/user/1000/run does not match our run root /run/user/1000: database configuration mismatch
```
#### Solution
To work around the new default path, we can manually set the path Podman is
expecting in a configuration file.
First, we need to make a new local configuration file for rootless Podman.
* `mkdir -p ~/.config/containers`
* `cp /usr/share/containers/libpod.conf ~/.config/containers`
Next, edit the new local configuration file
(`~/.config/containers/libpod.conf`) with your favorite editor. Comment out the
line starting with `cgroup_manager` by adding a `#` character at the beginning
of the line, and change the path in the line starting with `tmp_dir` to point to
the first path in the error message Podman gave (in this case,
`/run/user/1000/run`).
