Program Launchers on desktop not working after updates

[fehlix]

Here's the launcher that isn't working:
-rwxr-xr-x 1 trevorj domain users 283 Feb 17 2022 'IntelEvent Express.desktop'

The KiCAD launcher is working after clicking mark as execute.
-rwxr-xr-x 1 trevorj domain users 583 Aug 19 08:04 kicad.desktop

The permissions look identical

Hmm, can you post the output of this command.
Open terminal on Desktop:

Code: Select all

gio info 'IntelEvent Express.desktop'

and also the working one:

Code: Select all

gio info kicad.desktop

But please - for better readability - wrap the text output between those [code]brackets[/code] ( use the [</>] icon above the post editor)
thanks

Sorry for not using the CODE segment Felix. I figured it was OK since it was just 2 lines. I'll use it in the future. Here's the output. It's got me scratching my head. BTW when I deleted the launcher that wouldn't work and added it back from the main menu, it wouldn't even give me the launch security message when clicked. I was thinking this was because the checksum for that launcher is already calculated and that when I replaced the launcher thinking the launcher had become corrupt, replacing the launcer just put an identical file on the desktop and the checksum would have been the same.

space in the file name. I wonder if xfdesktop has a weakness in that area, although the other user that reported something similar did not have spaces in their filenames.

[dolphin_oracle]

hmmm, if the desktop files on the desktop are actually symlinks, the trust system will fail.

Here is the command in the launcher that is on the Desktop:

Code: Select all

env WINEPREFIX="/home/BPLSV/trevorj/.wine" wine C:\\\\ProgramData\\\\Microsoft\\\\Windows\\\\Start\\ Menu\\\\Programs\\\\IntelEvent\\ Express.lnk

That's the same command as the launcher in the main menu under the wine folder. To put it on the Desktop I just did a right click ans selected "Add to Desktop".

[FX-Tech]

BTW, That is the launcher that wine created when I installed the program.

So, are you saying, you still got the popup-warning to make the launcher executable?
That would be indeed unusual, b/c the checksum ( used for the trust-check is already generated).
Or, are you saying, after making the launcher executable ( and trusted) the launcher won't start the wine-program?

Hi Fehlix,

Click on the icon and nothing happens, no security warning pop up, no program execution, nothing. You can delete the launcher from the desktop, go to the wine folder in the main menu and right click on the launcher and select "Add to Desktop" to put a fresh copy on the Desktop and nothing still happens. It will not launch. Maybe a bug in the new security ? So was there a huge security issue that this new feature was addressing? Have personally never had any problem running programs from the Desktop. One of these days linux will be so secure that nobody can use it... ;-)

Cheers,
Trevor

So far I cannot re-produce the issue. Maybe completely different not the the trusted launcher, b/c it starts
but wont run wine. Make sure wine is not hanging and stop to start, e.g. logout or reboot.
Also you have a fairly unusual primary user group with a space within the group name "domain user". I tried to create a group with a space in the group-name but it won't allow me to. In addtion having not your home-directory under /home but within the sub-directory, may add further unusual setup, which triggers some other show stopper.

I’ve been trying to duplicate with wine apps as well but without success.
