-### 5) 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
-
-This problem has been fixed in Podman release 0.12.1 and it is recommended
-to upgrade to that version.  If that is not possible use the following procedure.
-
-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/tmp`).
