[Pkg-utopia-maintainers] Bug#956937: flatpak: "flatpak enter" dose not work

[treaki]

Package: flatpak
Version: 1.2.5-0+deb10u1
Severity: important

Dear Maintainer,

   * What led up to the situation?
    I tried flatpak today for the first time, installed an app and
    wanted to get a shell in its content to make some system settings
    (dark gtk theme), read manpage, found out about enter command,
    tried it but failed

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

----------------------------------------------------------------------
=== First Term ==
$ flatpak run org.midori_browser.Midori

Note that the directories 

'/var/lib/flatpak/exports/share'
'/home/user/.local/share/flatpak/exports/share'

are not in the search path set by the XDG_DATA_DIRS environment variable, so
applications installed by Flatpak may not appear on your desktop until the
session is restarted.


== 2nd Term ==

$ flatpak enter org.midori_browser.Midori bash

Note that the directories 

'/var/lib/flatpak/exports/share'
'/home/user/.local/share/flatpak/exports/share'

are not in the search path set by the XDG_DATA_DIRS environment variable, so
applications installed by Flatpak may not appear on your desktop until the
session is restarted.

Not running as root, may be unable to enter namespace
error: No such pid org.midori_browser.Midori
$ sudo flatpak enter org.midori_browser.Midori bash

   * What was the outcome of this action?
    to get some shell within that context
   * What outcome did you expect instead?
    error message with false statements (pid exist but it says it dose nto)


thanks in advance

Tim
