What are the values of $env:USERPROFILE, $env:HOMEDRIVE, $env:HOMEPATH and $env:HOME in your regular PowerShell?

Anakin-Hao commented 5 years ago 
$env:USERPROFILE
C:\Users\haoa

$env:HOMEDRIVE
H:

$env:HOMEPATH
\

$env:HOME
C:\Users\haoa
dscho commented 5 years ago

And if you open a Git Bash, what does pwd say?

Also, did you edit C:\Program Files\Git\etc\nsswitch.conf or a passwd in the same directory?

Anakin-Hao commented 5 years ago

No longer reproducible due to a new pc build at work.

@dscho Can you please re-open that issue, i get the same error inside vscode/cmd/powershell:

Home dir should be C:\Users\mseele

For the environment variables i go these results:

PS C:\dev\workspaces\eDMRTaskBasedView\git\eDMRTaskBasedView\ManageOneProductDataModelClient> $env:USERPROFILE
C:\Users\mseele
PS C:\dev\workspaces\eDMRTaskBasedView\git\eDMRTaskBasedView\ManageOneProductDataModelClient> $env:HOMEDRIVE

PS C:\dev\workspaces\eDMRTaskBasedView\git\eDMRTaskBasedView\ManageOneProductDataModelClient> $env:HOMEPATH
\Users\mseele
PS C:\dev\workspaces\eDMRTaskBasedView\git\eDMRTaskBasedView\ManageOneProductDataModelClient> $env:HOME
C:\Users\mseele

Git expected home dir to be /home/mseele which is wrong.

Occurs with all repos

dscho commented 4 years ago

Can you paste the output of where git?

dscho commented 4 years ago

(BTW this is technically a new ticket... but let's continue the conversation here.)

mseele commented 4 years ago

where git generates no output:

PS C:\dev\workspaces\eDMRTaskBasedView\git\eDMRTaskBasedView\ManageOneProductDataModelClient> where git

i don't want to create a new ticket because of the

I was not able to find an open or closed issue matching what I'm seeing

checkbox at the beginning of a new ticket. If you mind, i can open a new one!?

mseele commented 4 years ago

i need to correct myself:

where git generates no output under powershell. under cmd i see this output:

C:\Users\mseele>where git
C:\Program Files\Git\cmd\git.exe
dscho commented 4 years ago

If you mind, i can open a new one!?

No, please don't worry about that.

where git generates no output under powershell. under cmd i see this output:

C:\Users\mseele>where git
C:\Program Files\Git\cmd\git.exe

That is the expected output. However, maybe you have a HOME environment variable set already? Like, what does your PowerShell say when you ask echo $env:HOME? Or for that matter, HOMEDRIVE, HOMEPATH and USERPROFILE?

rimrul commented 4 years ago

They already included the values of all those variables in their first comment under "what did you expect..."

mseele commented 4 years ago

powershell:

PS C:\Users\mseele> echo $env:USERPROFILE
C:\Users\mseele
PS C:\Users\mseele> echo $env:HOMEDRIVE
C:
PS C:\Users\mseele> echo $env:HOMEPATH
\Users\mseele
PS C:\Users\mseele> echo $env:HOME

Whoops, I was on my phone and could not find it... Sorry.

powershell:

PS C:\Users\mseele> echo $env:USERPROFILE
C:\Users\mseele
PS C:\Users\mseele> echo $env:HOMEDRIVE
C:
PS C:\Users\mseele> echo $env:HOMEPATH
\Users\mseele
PS C:\Users\mseele> echo $env:HOME
c:\Users\mseele

That looks correct to me.

So that leaves pretty much only one option: that the /etc/nsswitch.conf became incorrect somehow. Can you check that the line talking about db_home lists env first? This is how it should look like:

db_home: env windows cygwin desc
mseele commented 4 years ago

this is my /etc/nsswitch.conf under c:\Program Files\Git\etc\nsswitch.conf:

# Begin /etc/nsswitch.conf

passwd: files db
group: files # db

db_enum: cache builtin

db_home: env windows cygwin desc
db_shell: env windows # cygwin desc
db_gecos: env # cygwin desc

# End /etc/nsswitch.conf
dscho commented 4 years ago

@mseele hrmpf. This looks correct, so it looks very weird to me that your OpenSSH decides to use /home/mseele.

It's just one more weird thing on this already weird day.

When I try to run an integrated terminal in my copy of VS Code, I fail to see the behavior you see. When I call git -c alias.s="!ssh-keygen" s, it shows me a path in my actual home directory (as opposed to /home/<my-username>).

Do you maybe have an MSYS2 or Cygwin on your PATH? Although that should not matter: Git for Windows should prepend its own MSYS2's /usr/bin. So this is disconcerting. Can you ensure (e.g. via the Task Manager, by clicking on the properties of the running process) that the ssh process you see is actually started from C:\Program Files\Git\usr\bin\ssh.exe?

No, there is not MSYS2 or Cygwin on the path. when i run git push, process_explorer generates tree processes in this order:

That is most strange. Maybe you can log verbosely by passing a couple -v flags, and maybe that will tell us where this home directory is configured?

mseele commented 4 years ago

which commands can i run with -v? We can also do a screensharing session if that helps!?

dscho commented 4 years ago

ssh -v -v -v ... should log verbosely. (sorry, I'm still struggling with the v2.25.1 release, and won't have time for screensharing today)

no problem and no rush for that, i just thought that would help to solve that strange problem...

dscho commented 4 years ago

running .\ssh.exe -v -v -v ghlx06.guh-local.de from C:\Program Files\Git\usr\bin gives me that

PS C:\Program Files\Git\usr\bin> .\ssh.exe -v -v -v ghlx06.guh-local.de

This part would have been enough to determine that ssh does not really read any other configuration file before trying to use /home/mseele as your home directory. At this point, I am at a loss what it could be.

maybe important: when i run ssh from somewhere else, i get:

PS C:\Users\mseele> ssh -v -v -v ghlx06.guh-local.de
OpenSSH_for_Windows_7.7p1, LibreSSL 2.6.5
[...]

This is most likely the native Windows OpenSSH:

C:\>where ssh.exe
C:\Windows\System32\OpenSSH\ssh.exe

no problem and no rush for that, i just thought that would help to solve that strange problem...

Given that this is a rather rare problem, and given that it would take some debugging skills on the part of somebody who has a setup where the problem can be reproduced, I think this is low priority.

If you want to investigate further, I would suggest trying to analyze the output of strace -o ssh.trace ssh.exe ghlx06.guh-local.de; maybe there is some clarity to be gained from that strace.

mseele commented 4 years ago

The output of strace -o ssh.trace ssh.exe ghlx06.guh-local.de is

PS C:\Program Files\Git\usr\bin> .\strace.exe -o ssh.trace ssh.exe ghlx06.guh-local.de
Could not create directory '/home/mseele/.ssh'.
The authenticity of host 'ghlx06.guh-local.de (192.168.100.87)' can't be established.
ECDSA key fingerprint is SHA256:6NYrSy8LS0RjSFHOUrTbyuF/ycc/dv8xhCm9IgXP0qM.
Are you sure you want to continue connecting (yes/no/[fingerprint])?

Is there a way to use another ssh client instead of the included ssh client? GIT_SSH is ignored in git for windows (https://git-scm.com/book/en/v2/Git-Internals-Environment-Variables), right? Or is there any other way to configure the home path for ssh? This is a real stopper for us :/

rimrul commented 4 years ago

Isn't that just the output of the ssh command? Looks to me like the strace output landed in a file C:\Program Files\Git\usr\bin\ssh.trace.

mseele commented 4 years ago

You're right, sorry for that. I've attached the ssh.trace file:

ssh.trace

rimrul commented 4 years ago

Lines 86-88 seem interesting. Line 88 is the first occurence of /home/mseele in pwdgrp::fetch_account_from_windows and the lines before it mention a windows error 1355 in sec_auth.cc:367.

Windows error 1355 seems to be related to authentication against a domain controller.

mseele commented 4 years ago

I Know that our company has a domain controller and linux home directories for every user. But is it not possible to override this or detect that we are under windows and should use the windows home dir...not the remote linux one?

dscho commented 2 years ago

Closing this as stale.

OscarL commented 1 year ago

This is an old issue, but... For what it's worth...

I was having that same Could not create directory '/home/<USER_NAME_HERE>/.ssh' issue.

I solved it by making sure that the etc\ssh\ssh_config file on my local copy of MinGit includes a line at the end pointing where I want:

IdentityFile D:\<USER_NAME_HERE>\ssh\id_ed25519

Now I can git push from my weird cmd.exe+click+GoW+MinGit setup, if I need to, and I'm happy :-)

DouglasRoyds commented 1 year ago

FWIW, an strace excerpt from the same error on my machine attached: could-not-create-dir-ssh.txt

I am logged in to this machine via an LDAP domain. The machine has previously had cygwin installed.

I attempted a directory symlink as C:\Program Files\Git\home\roydsd\.ssh, which silenced the Could not create directory error, but then public key authentication failed, probably due to file permission errors (ssh is fussy about that).

I tried putting /c/Windows/System32/OpenSSH to the front of the PATH, to use the built-in ssh client, but this also failed:

Pseudo-terminal will not be allocated because stdin is not a terminal.
CreateProcessW failed error:193
ssh_askpass: posix_spawnp: Unknown error
Host key verification failed.
