There can be a number of reasons for this. One common reason is that the SID belongs to a domain account and the domain is not accessible. Another is that the SID belongs to a local account on a different computer (e.g., a removable disk is moved between computers and local accounts are in the ACL). This is essentially what happened (removable disk moved from one computer to another). Well-known SIDs (e.g., S-1-5-32-544 for the local Administrators group, etc.) should resolve from any computer. I would think so too, but that doesn't appear to be happening.If it makes a difference, the SID actually starts with S-1-5-21. I have to manually take ownership in order to even access the files at all. - Brent -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

This will ensure that all permissions are set correctly, and all programs are rebased correctly as well. This is because Windows uses a very different file access control that that of simple POSIX permissions, on top of which Cygwin emulates them. If you want your pain to be somewhat less in the future, move your home away from Cygwin directory and use noacl flag on it, which will defer permissions control to the underlying OS layer. I'm using my Windows profile as Cygwin home, but your mileage may vary. Thanks, I did try a clean install of cygwin. This has not resolved the issue. I think what's happened is that some of all files modified by by various command line programs (git, rsync, etc.) in cygwin have ended up with permissions that didn't carry across with the new Windows installation. In the [Security] tab for these files or directories, under "Group or user names", it lists the owner as "Account Unknown(S-...)".

Re: Continued rsync failures
Sorry, my silly mail client doesn't reply to the list by default. -- It might be worth noting that these rsync commands run using an on-demand script to manage sync jobs. Generally, it will execute rsync once with `--dry-run` to gather a list of files for me to preview: rsync -avi --progress --no-perms --no-owner --no-group --delete --dry-run -s --exclude-from='/cygdrive/d/my/exclusion/file' --exclude-from='/cygdrive/d/my/additional/exclusion/file' /cygdrive/d/path/to/source'/. '/cygdrive/d/path/to/target' trace file: http://cygtestdata.ddnsfree.com/strace.exec1.out Then it can run rsync a consecutive time: rsync -avi --progress --no-perms --no-owner --no-group --delete -s --exclude-from='/cygdrive/d/my/exclusion/file' --exclude-from='/cygdrive/d/my/additional/exclusion/file' /cygdrive/d/path/to/source'/.

RE: Is there a way to clone-install Cygwin?
Fair enough. I don't think I've encountered any scripts that modify the system in my use of cygwin, so I didn't think of it. You're correct, "mostly portable" is more accurate.

Re: Is there a way to clone-install Cygwin?
Sorry, this reply was meant to go the list but I was using a different mail client and it replied directly. __ Cygwin is totally portable! You can simply copy the installation folder to another PC, copy the shortcut (edit target if needed) and it will work. I've done this numerous times for this exact reason. You may also want to copy the package directory and setup log if you want to update the installation on the clone.

Re: mintty window flashes open and immediately closes
Hello Andrey, The way I ended up "solving" this is by restoring a backup of cygwin I had from a few weeks ago. Almost nothing had changed with my working files, so I considered it good enough and called it a day. However, I kept a copy of the failed/corrupted install and put it in a VM so I can continue to diagnose the failure. Interestingly, it exhibits the same failure within the VM, so now we know it's not something within the specific Windows environment. Also worth noting, the host environment is Windows 7, the VM guest is Windows 10. I took your suggestion and ran `rebase-trigger full`, closed cygwin windows, and re-ran setup. It has not resolved the problem, unfortunately. - Brent On 2019-12-21 08:31, Andrey Repin wrote: Greetings, Brent Epp! I've been using cygwin for years with no problems.

Re: mintty window flashes open and immediately closes
This is interesting: I have a backup copy of my cygwin installation from
2 days ago. I restored it to another folder, made a shortcut... and it
works.
I'll have to run some diffs to double-check, but I'm pretty certain the
only thing that's changed in the past two days is that I ran the latest
installer today to update.

Probably a problem with your bash init scripts.
Try (for the shortcut): C:\cygwin64\bin\mintty.exe --noprofile --norc -
If that works, then start spelunking those init files (.bashrc,
.profile, /etc/{profile,bash.bashrc}).
BTW you don't need to call bash in the shortcut, mintty by default opens
bash with those parameters; but the "-" at the end is required.
