I have that mess too, no solution.
I never find the link for download, repository or whatever.
Let’s say https://store.kde.org/p/999991/ or https://www.gnome-look.org/content/show.php?content=164300 in which there are not any files under the
Files tag in pages.
I read comments of people having locks issues solved by the author using dropbox,. However neither for these have links! But this not seems to be so for me cause there are some apps available, recently ones the most.
Sometimes there is a warning message about archived files.
In case of archived or blocked applications, is there any way to get them?
