Program Launchers on desktop not working after updates

Hi Guys,
This morning when I came into work and fired up the machine, all seemed normal until I tried to launch some applications from the desktop. When I click on a program launcher on the desktop, I get an error message. Here's a screenshot of the error:

Anyone else seeing this? I know there were a bunch of updates late in the day yesterday.
Thanks ,
Trevor

click "mark executable" and it should be OK after that. Xfce 4.18 introduced an additional security check where it compares a checksum against the desktop file. if the checksum is not present or doesn't match, you get that popup.

That does not do the trick. Sorry I forgot to mention that I had tried that.

Dont's see that as an Error . It a new addtional "security measure about trusted application launcher brought to you by new upgraded version of Xfce.
Just click on "Mark executable" to make it trusted.

BTW, the program that is giving me the problem is run under wine. The launcher works from the menu under wine folder, but not from the desktop. I've also tried deleting it and re adding it from the main menu (right click - add to desktop) and that doesn't work either.

Hmm this was mentioned by someone else... maybe permission issue with the home folder.

Are you saying it's only one launcher that won't work and for all others let you mark as trusted work.
Perhaps show details like this,
open terminal on desktop and run:

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

The only thing different about this launcher that I know of, is that it is a windows program run under wine. It's worked flawlessly this way all through MX-19 and MX-21 so far until now. This machine is a member of a windows domain - but I don't see that being the issue as the other programs, like KiCAD do launch ok. Thanks for your help. Hope it's not a wide spread issue!

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:

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.

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".

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.

Hey Guys,
So, this machine is a member of a Windows AD Domain. That's a normal home folder location for a user on a domain. There is usually a folder under home indicating the name of the domain and that users in that folder are members of the domain. The same launcher works from the side bar AND the main wine menu. Wine is not hanging.
You probably can't reproduce the issue if it is an issue with being a member of a domain. It's only not working if the launcher is on the desktop. Probably not a lot of MX users are using machines that are members of a domain. Is there any way to turn off this new "Feature"?
Thanks,
Trevor

Thought I'd change the launcher to open in a terminal to see if there was any useful output:

Would this wine command shown in the launcher run within terminal opened within the desktop directory:

Hi Fehlix,
Yes, I saw that too, but this launch command was generated directly by wine when the program was installed and has worked flawlessly for several years, until now. I did try changing the line and it made no difference. Thanks.

That was meant as a question whether the env -line runs or not, from terminal opened in Desktop directory?

Just realized I attached the wrong screen shot of the terminal. The previous one is when I had modified the command line to remove spaces. This is what the terminal output looks like with the command line that wine generated and has always worked:

I hate terminal text posted as screenshot images!
OK, can you run the same command I posted from Terminal
but this time change first directory to $HOME:
Open Terminal:
Code: Select all
cd $HOME
env WINEPREFIX="/home/BPLSV/trevorj/.wine" wine C:\\ProgramData\\Microsoft\\Windows\\Start\ Menu\\Programs\\IntelEvent\ Express.lnk

OK, seems I can reproduce, something with the quotings within the launcher on the desktop:
This type Exec line of launcher worked for me from with the launcher but als from the terminal CLI :
Code: Select all
Exec=env WINEPREFIX="/home/BPLSV/trevorj/.wine" wine "C:/ProgramData/Microsoft/Windows/Start Menu/Programs/IntelEvent Express.lnk"
So right click on the Launcher on the Desktop and replace the command with
Code: Select all
env WINEPREFIX="/home/BPLSV/trevorj/.wine" wine "C:/ProgramData/Microsoft/Windows/Start Menu/Programs/IntelEvent Express.lnk"
or alternatively open in Text editor and replace the Exec= line
+++EDIT+++
Opps corrected ... again: mainly repalce all "\\" with "/" and "\ " with just " ",
and put all int double quotes
++EDIT 2 +++
Here the way to reproduce the issue:
I've installed within wine, Total Commander,
which created this Launcher on the Desktop:
Code: Select all
[Desktop Entry]
Name=Total Commander
Exec=env WINEPREFIX="/home/demo/.wine" wine C:\\\\Program\\ Files\\\\totalcmd\\\\totalcmd.exe
Type=Application
StartupNotify=false
Comment=C:\\Program Files Totalcmd
Icon=B838_totalcmd.0
StartupWMClass=totalcmd.exe
Path=
Terminal=false
and gave the same error of not starting:
now I replaced the Exec line with
Code: Select all
Exec=env WINEPREFIX="/home/demo/.wine" wine "C:/Program Files/totalcmd/totalcmd.exe"
so the Desktop-launcher looks like this:
Code: Select all
[Desktop Entry]
Name=Total Commander
Exec=env WINEPREFIX="/home/demo/.wine" wine "C:/Program Files/totalcmd/totalcmd.exe"
Type=Application
StartupNotify=false
Comment=C:\\Program Files Totalcmd
Icon=B838_totalcmd.0
StartupWMClass=totalcmd.exe
Path=
Terminal=false
which worked, /after marke as trusted.
So the whole issue seems related to the handling of those quadro "\\\\" backslashes with the Desktop launcher, created by wine-installer, which appears to be now an issue within Xfce 4.18. ... Ufff..
+++ EDIT 3 +++
Or alternatively:
* Replace all "\\\\"-quadro backslashes with one "/"-forward slash.
* Replace "\\ " double-backslash+ space with "\ " one backslash and space
Or this one liner running with terminal in the Desktop directory, which would fix all wine launchers on the Desktop in one go:
Code: Select all
perl -i -pe 's/\\{4}/\//g; s/\\{2} /\\ /g;' *.desktop
+++ EDIT 4 +++
This is the "final" solution use only forward-slashes and quotes . Replace all "\\\\"-quadro back-slashes with a single "/" forward-slash
and replace all "\\ " double-slash + space with a double-quoted space " ":
As one liner:
Code: Select all
perl -pe 's/\\{4}/\//g;s/\\{2} /" "/g;' *.desktop
This makes sure, any future Xfce-fix of desktop launcher, which may properly handle "\\\\" and "\\ " bask-slashes, by using only a "forward"-slashes and quote spaces.

Hey Fehlix,
Thought I posted a reply a few minutes ago, but I must have not. Anyway, I solved it by making a new launcher and using this command line:
Code: Select all
env WINEPREFIX="/home/BPLSV/trevorj/.wine" wine C:\\ProgramData\\Microsoft\\Windows\\Start\ Menu\\Programs\\IntelEvent\ Express.lnk
It works in a newly created launcher. It seems that wine uses a single "\" to indicate a space and "\\" to indicate a folder branch. Not sure why there were 3 of them in places, but obviously there is an issue with the new security and wine. Maybe the new launcher automatically marks it as trusted? Just guessing here as I have no idea how the new security feature works.
Thanks for your help guys!
Cheers,
Trevor

Nope, that's a strong indication of a regression ( a bug), nothing todo with security. The old quador- "\\\\" backslashes
where needed, b/c desktop files when "started" would first replace "\\\\" with "\\".
Next step would be to pass this argument to wine, which would then replace "\\" with "\"
As it works from the menu, that#s an clear indication the new Desktop-launcher handling introduced
this issue. Not an issue with the new trusted feature, but an regression withn the new code for handling launchers.
So suggest, to use my adjusted fix "with "forward slashes, b/c they may fix the issue,
to work properly with quadro- "\\\\" backslashes again, which would than make you "\\"-double backslash solution not work. (see "EDIT 4" with my last post above...)

I have never had a launcher created by Wine because I use Windows programs that are called "portable". This has the advantage that you don't have to install them when moving or reinstalling, but a copy from the backup is sufficient.
I wrote my first launcher in 2014 under opensuse, since then I have only edited it when a new version of the programme came out.
My exec line looks different.
Code: Select all
[Desktop Entry]
Version=1.0
Type=Application
Name=JPG-Illuminator V54
Comment=JPG-Illuminator
Categories=Graphics;windows;
Exec=wine start /Unix "/home/winnI/winetc/JPG-Illuminator-54/jpgIlluminator.exe"
Icon=/home/winnI/winetc/wineapps/ji.png
Path=/home/winnI/winetc/JPG-Illuminator-54
Terminal=false
StartupNotify=true
GenericName=JPG-Illuminator
Name[de_DE.utf8]=jpg-illuminator V54
It worked like that on opensuse 12-42, all mint and ubuntus between 2014-2016 and since 2018 on MX.
I have about a dozen starters of this type, so that they appear in the fluxbox menu (formerly xfce menu) as executables, the *desktop files are all under /home/username/.local/share/applications .
This is also where the desktop files of appimages belong, if you use a program like the Appimage Launcher, it does the work for you :)
