Network Manager Applet Icon error on VPN Connection

[Hugo]

The Network icon in the top panel doesn't change to the icon with a lock when a Palo Alto VPN Network is conected.

In ubuntu Mate 16 and 18 the default behavior was to change the icon adding a small size lock.

In Ubuntu Mate 20, in Traditional Desktop, seems something is missing. When connecting to the VPN, icon changes to a black screen with a forbidden icon (see attachment).

Same bug here!
Network Manager icon chashes after connect to OpenVPN account.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

Could you add your 'journalctl -b 0' log after getting the issue? it seems rather an icon theme bug than an applet one though

Same here. No icon when connecting to a strongswan VPN.

journalctl -b 0 shows this entry everytime I connect to the VPN (with different time stamp and different number in brackets each time);

I think the problem is with the nm-signal-*-secure.svg images found in at least Ambiant-MATE and Radiant-MATE themes.

With strace I can see that 'mate-indicator-applet-complete' tries to open '/usr/share/icons/Ambiant-MATE/status/22/nm-signal-75-secure.svg' but after that it displays '/usr/share/icons/Humanity/status/22/image-missing.svg' instead.

Opening '/usr/share/icons/Ambiant-MATE/status/22/nm-signal-75-secure.svg' with Inkscape dispalys multiple errors like this:

nm-signal-75-secure.svg:34: namespace error : Namespace prefix inkscape for current-layer on namedview is not defined
kscape:zoom="10.375" objecttolerance="10.0" pagecolor="#ffffff" showgrid="false"

Opening with cairosvg prints:

xml.etree.ElementTree.ParseError: unbound prefix: line 34, column 2

A Workaround that works for me: Inkscape, beside the errors, can open the images and by saving them, overwriting the originals, fixes the missing image problem.

Thanks for the debugging, that indicates the issue is with the icon theme not the indicator
