mintinstall: after installing an app flatpak cannot be launched

[haggen88]

after installing a flatpak app, it cannot be launched, either from mintinstall or the cinnamon menu: (tested in live usb mode - mint-common 2.3.3)

e.g flatseal:

mint@mint:~$ mintinstall MintInstall: low resolution detected (768px height), limiting window height. MintInstall: Detected system architecture: 'x86_64' MintInstall: Deleting old screenshots Mintinstall startup took 4691.304 ms MintInstall: No new reviews Launching app with Popen: /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=com.github.tchx84.Flatseal com.github.tchx84.Flatseal bwrap: Creating new namespace failed: Permission denied error: ldconfig failed, exit status 256

• I also have problems when trying to uninstall the app from the cinnamon menu (the app can be uninstalled from software manager).
