You are replacing a directory with an ordinary file. The requires a
%pretrans script. %pretrans scripts must be written in lua:
%pretrans -p <lua>
st = posix.stat("%{_datadir}/applications/%{name}.desktop")
if st and st.type == "directory" then
os.execute("rm -rf %{_datadir}/applications/%{name}.desktop")
end
Wow. Shouldn't RPM support this out of the box?
Should? Sure, it seems like an obvious thing on the surface, but
replacing directories within a transaction is very complicated due to
removals happening after installs (and rpm's file fingerprinting semantics).
The new thing here is that rpm >= 4.11 detects and reports the
(unsupported) attempt to replace a directory with something else as a
conflict, previously it just barfed up with "cpio: rename failed - Is a
directory" error in middle of transaction.
An easier-than-pretrans-hack workaround is to just use a different
filename for the file replacing the directory.
