Public bug reported:
The "Main Menu" editor no longer shows the listings for installed
applications.
This may be related to how the 26.04 LTS preview now handles filename
restrictions.
Example, non-snap apt install of firefox package from (ppa:mozillateam/ppa) :
xdg-desktop-menu install /usr/share/applications/firefox.desktop
xdg-desktop-menu: filename 'firefox.desktop' does not have a proper vendor
prefix
A vendor prefix consists of alpha characters ([a-zA-Z]) and is terminated
with a dash ("-"). An example filename is 'example-firefox.desktop'
Use --novendor to override or 'xdg-desktop-menu --manual' for additional info.
Which will not load until the format encoding parser passes validation.
Temporary workaround:
sudo ln -s /usr/share/applications/firefox.desktop
/usr/share/applications/mozilla-firefox.desktop
Will bypass the issue, while not impacting the same .desktop file
deployed unchanged since 24.04 LTS.
Looking forwards to the LTS release this year, Cheers =)
