Re: git clone fails with error chmod on config.lock failed: Invalid argument


My passwd and groups files got automatically renamed. I can't identify the exact date. Last update of cygwin I did yesterday, but the rename could happen a long time ago.

> ls  passwd* groups*
passwd.backup groups.backup

> groups
groups: cannot find name for group ID 10749228312
10749228312 ZTB+Group(513) Administrators Users ..... ZTB+Group(1298252)...

ZTB is my AD domain. Seems that any of the groups that I have assigned on the domain level was not resolved.

In the old groups.backup there is a record:

BTW: My machine is Windows Server 2008, yesterday I also run the Windows update procedure before I notified the chmod error. A months ago, I had to migrate to the new AD account. The cygwin was installed using my old account, which is deleted now. Is it possible that the query to AD runs under my old account?

What I see from the strace, chmod fails to request group information:

299755  597014 [main] chmod 5840 internal_getlogin: group not found in group DB

So it looks like either your /etc/passwd or your /etc/group file is
broken.   The new account handling is a bit more sensitive to broken
passwd and group files.  For more information on the changes in account
handling see

For a start, just move both files out of the way, stop your Cygwin
processes and try again.
