After installing LibreOffice update, I clicked on Menu "Help > Check for update" (to be sure to have the last version) and LibreOffice displayed the attached message containing the string %PERCENT% which stays endlessly.
LibreOffice Version : 126.96.36.199, french (if it matters)
Note 1: after a LibreOffice restart the same opérations in the menu returns the correct pop-up window content (ie "LibreOffice is up to date").
Note 2: I have no network issue at all!
Created attachment 131705 [details]
Window popup with PERCENT when checking for update
Add screen capture
I can't reproduce it in
