I use several scripts but basically do this:
then further to
(can be staging or stable) On the page search type ex.: 4.21
now skip all packages containing:
-dev, as the above ones.
copy them all to a folder named ex.: wine4.21-bionic (if it was stable could be instead wine4.21stable-bionic)
Extract them all using the filemanager (is easier, I use
nemo). Expand all the 4 folders to see simultaneously all the
data.tar.xz, select all these 4 and do "extract here" (will be on the sub-folder).
Now rename 2 of the 4 folders at
wine4.21-bionic/ to (just keep their ending folder name):
Copy the subfolders
usr from the remaining folders (the extracted but not renamed ones), and paste into the renamed folders (you must opt to merge the folders now).
Cleanup/Trash everything else that is not needed.
nemo there is
open as root context menu option. So I use it to move that folder and apply root permissions to top folder and all enclosed files.
you will need these environment set after that, (I keep them at a top folder: /WineVersions/) ex.:
/usr/lib/x86_64-linux-gnu may not be necessary above (try w/o it first?), but I use it anyway)
now you should be able to ex.:
wine64 explorer (after you create and env set a WINEPREFIX of course :))
