Hello,

Try to call StarUML from terminal using the "--no-sandbox" option. This works on last StarUML version (3.2.0). This option need to be applied even if you launch application from the ".desktop" icon file

Regards,

Paolo

Hi Paolo,

Thanks for the workaround. Yes, StarUML works that way. I can add the option to the menu item, no problems. However, running StarUML with --no-sandbox has its own problems.

When I run StarUML that way, it starts with a half decorated window. Please see the attached image:

StarUML stays in this state even if I open a document. Only way to fix it is to create a new window by either creating a new document by File -> New or open another document while a document is open (so forcing StarUML) to create a new window. I'm not sure how this is tied to --no-sandbox option though.

Thanks again,

Best regards,

Hakan

This is the same behaviour I see in my Debian Jessie. The --no-sandbox is a workaround I found to open the application. I hope that the mainteners will fix that issue soon

I just checked with the AppImage of the current release. If you extract the image and set the permissions correctly everything works find.

Thus, I consider this a packaging issue. It would be great if the guys at Staruml would fix this.

regards

Try the below command. It works for me.

$ sudo sysctl kernel.unprivileged_userns_clone=1

Hi Minkyu,

Setting that sysctl doesn't look like a wise idea. Looks like enabling it opens a big can of worms of security problems or weaknesses. Hence, I'll pass. Thanks.
