Just a simple `d2u filename` is enough to trigger the problem.

$ ls -ld . ./Localization.lua
drwxr-xr-x 1 anrdaemon None     0 янв  2 12:07 .
-rw-r--r-- 1 anrdaemon None 32212 янв  1 14:32 ./Localization.lua

$ /usr/bin/d2u ./Localization.lua
dos2unix: Failed to change the permissions of temporary output file ./d2utmpEBELkH: Permission denied
dos2unix: problems converting file ./Localization.lua

$ getfacl . ./Localization.lua
getfacl: .: Not supported

getfacl: ./Localization.lua: Not supported

cygcheck output attached.
