Thank you for your bug report, there were some fixes around escaping
upstream but unsure that specific issue is fixed (e.g
https://gitlab.gnome.org/GNOME/network-manager-applet/commit/2a65e932)
** Package changed: gnome-control-center (Ubuntu) => network-manager-
applet (Ubuntu)
** Changed in:
Adding wpa2-tls-root-cert-no-spaces.png which shows settings are
acceptable, the red box disappears and the connect button becomes
available when file is renamed to remove spaces.
** Attachment added: "Shows settings are acceptable when file is renamed to
remove spaces."
Added spaces-fine-in-connection-edit-window.png showing that the edit
connection window will accept spaces in filenames.
** Attachment added: "Edit connection window will accept spaces in filenames"
