File permission issues on Cygwin directories and files can sometimes be
clarified by running `setfacl -b|--remove-all` which removes all *extended* ACL
entries, and reduces ACLs to match effective POSIX permissions, which can then
be fixed by `chmod -c|-v perms files`.
I use `lsattr -adl ...` on directories, `ls -adl ...` on directories and files,
`getfacl ...` on directories and files, and `icacls $(cygpath -am ...)` to look
at permissions.
If `chmod -c|-v perms files` does not fix an issue, I carefully use
`setfacl -m acls files` to make ACLs look normal.
[I have found running `setfacl -k|--remove-default` which removes all default
ACL entries DACLs on Cygwin or non-Cygwin directories means nothing can create
anything under those directories as no DACLs are there to define default
permissions.]
Eventually I booted to knoppix, deleted the offending file, booted to
windows and reinstalled the cygwin package.
That fixed the problem.
Good to hear.
You could just launch MS Windows File Explorer `cygstart .` or `cygstart /` and
delete the offending file(s).
Thanks for your help.
Most such problems happen because something has been running and not yet
terminated before running Cygwin Setup, or Windows Scheduled Tasks running
Cygwin processes while running Cygwin Setup.
I start Task Manager, tab Details, sort by Image path name, check for anything
running from Cygwin install paths, and kill them, then run Cygwin Setup.
After checking all Cygwin postinstall processes have completed, as above, I
check thru /var/log/setup.log.full for any significant issues, and rerun Cygwin
Setup if required.
My Cygwin login profile checks for not-yet-replaced binaries:
/usr/{{,s}bin,lib}/*.{dll,exe}.new
and not-renamed non-permanent postinstall scripts:
/etc/postinstall/[!0z][!pqrst][!_]*.*sh
and their existence tells me something did not complete successfully.
