Error : Askpass.exe: No such file or directory
Asked by Reza:

Hi All,

After updating sourcetree I seem to be getting this error

```
git -c diff.mnemonicprefix=false -c core.quotepath=false fetch origin
fatal: HttpRequestException encountered.
An error occurred while sending the request.

error: cannot spawn C:\Users\Reza Seedin\AppData\Local\SourceTree\app-3.0.5\tools\Askpass.exe: No such file or directory
bash: /dev/tty: No such device or address
error: failed to execute prompt script (exit code 1)
fatal: could not read Username for 'https://github.com': No error

Completed with errors, see above.
```

I have tried to re-adding my username password as well. Any thoughts?

This should improve the situation significantly and we'd recommend upgrading.

comments: author: Reza
body: Hi Michael, Does this come automatically with Source tree (version 3.0.8?) or do we need to update this separately as per your link above. I have have fallen back to 2.6.10


author: minnsey
body: It is not in 3.0.8.  

Deepening on how quickly it gets bundled into a Git release it will get put into a future Sourcetree release.


author: Mark Graves
body: Windows Credential Manager: 1.18.3

SourceTree: 3.0.8

Git: 2.19.1

EVERYTHING WORKS NOW!!


author: Reza
body: Hi [@minnsey](/t5/user/viewprofilepage/user-id/502201),

Can confirm that after the update to the GMC manually <https://github.com/Microsoft/Git-Credential-Manager-for-Windows/releases/tag/1.18.3> this work fine with SourceTree: 3.0.8 with embedded GIT for me.

Thanks all and thanks to the team at Sourcetree. Keep up the good work

body: Thank you. Now it works.


author: Thilo Enters
body: Had the same issue today, the following workaround helped:

1. Go to an old installation of SourceTree, for me it was here:  
   C:\\Users\\\<username\>\\AppData\\Local\\SourceTree\\app-2.6.10\\tools
2. Select the following files and copy them  
   Askpass.exe  
   Askpass.UI.Wpf.dll  
   SourceTreeShared.dll
3. Paste the files you copied in the following directory:  
   C:\\Users\\\<username\>\\AppData\\Local\\SourceTree\\app-3.0.6\\tools

body: This work-around worked for me. I have two connections setup VSTS and a Githhub account. VSTS worked fine and Github worked fine when accessing repositories I created, but when trying to access a private repository I have contributor access to the above work-around was needed.


author: bpiec
body: This workaround works but still outputs an error:

```
fatal: ArgumentException encountered.

?? An item with the same key has already been added.
```


author: Daniele Tullo
body: hi,

had the same issue.

Switching to git version "system", updating embedded and going back to "embedded" seemed to fix it...

with each update, i need to pray all divinities that everything is still working...

comments: author: Reza
body: I made the infortunate mistake of hitting update on a Friday before I went on vacation. I didn't realise it was a version 2 to 3 change. I'm back to 2.6.10 and happy days again


author: Mark Graves
body: I encountered this same problem today after updated my system Git version to 2.19.1. I also updated SourceTree to 3.0.6 at the same time. When pushing a branch, I get the following error:

fatal: ArgumentException encountered.

An item with the same key has already been added.

error: cannot spawn C:\\Users\\mark.graves\\AppData\\Local\\Sourcetree\\app-3.0.6\\tools\\Askpass.exe: No error

When pushing in this state, I received no prompt to provide credentials to my Git Credential Manager. Once I changed to use the embedded Git version 2.18.0, I DID get a prompt to provide credentials to the Git Credential Manager, and everything started working.

body: How do you change to use the embedded Git?


author: Mark Graves
body: Tools =\> Options =\> "Git" tab =\> click the "Embedded" button.


author: Gary Miner
body: Ran into this issue today with git 2.19.1 and SourceTree 3.0.8. Switching to the embedded git version works.


author: Mark Graves
body: I can also confirm this happened to me on 3.0.8 today after upgrading from 3.0.6. I switched back to using embedded git version 2.18.0 to fix the issue again.


author: Gary Miner
body: I think the issue with 2.19.1 is due to this <https://github.com/Microsoft/Git-Credential-Manager-for-Windows/issues/774> which isn't a sourcetree issue per se. I updated my git-credential manager as suggested in this link and I'm working fine with 2.19.1 again.


author: Simon_Thom?
body: Updating Sourcetree to 3.0.8 and system Git to 2.19.1 I still have the same problem, I can also confirm it is working on embedded Git 2.18.0


author: minnsey
body: Hi  

Firstly thanks for flagging this up, it does look like a bug that we will look into.  

However Askpass.exe should only be used if the Git Credential Manager, GCM, has failed to retrieve credentials, either from storage or by prompting you the user.  

I think that is why we missed this bug because we never hit that state.  

Were you prompted at all with a Graphical UI for your GH credentials?  

If you haven't already can you try installing Git 2.19.1 as this contains the latest GCM version and then switch Sourcetree to use it as a System Git in the Tools/Options/Git tab

comments: author: atompkins
body: I had the same problem. No prompt. Git already 2.19.1.

I have rolled back.


author: Simon_Thom?
body: Hi,

I also have a similar problem. I updated Sourcetree to 3.0.6 and simultaneously changed our repositories to use SSL. I am using System Git 2.19.1, I get the following error:
> fatal: ArgumentException encountered.
>

Switching to embedded Git 2.18.0 seems to fix it for now.


author: Maxim Beliy
body: Neither embedded 2.18.0 nor system 2.19.1 worked. Still no prompt and error "No error".

Uninstalling sourcetree 3.0.6 and installing latest from sourcetree site (2.6.10!) helped.


author: Steve Esson
body: Same as Maxim, steer clear of v3!


author: Reza
body: I was not prompted, I have reverted back to 2.6.10. Embedded git worked for my oragansations GIthub but I am a contributed to one of my clients which still did not work.

Reverted and now up and running.


author: minnsey
body: A fix for this will be in Sourcetree 3.0.8 which should be rolling out this week.

comments: author: Ultroman
body: It was clearly not. Please get on this ASAP. Apparently, one has to install extra software, to make this software stop throwing errors.


author: Ahmed Tarek
body: Same Problem with me after updating from 2.6.10 to 3.0.6


author: John Lewin
body: Also running into this error on fetch in SourceTree. Fetch command line via git works as expected without error

\>Were you prompted at all with a Graphical UI for your GH credentials?  
No prompts at all, just an endlessly spinning 'Fetching' dialog box

Switching to embedded works around the issue for now


author: bpiec
body: Two weeks and the bug is still not fixed (but it breaks one of the main features of Source Tree for many users). I also filed a bug: <https://jira.atlassian.com/browse/SRCTREEWIN-9318> but didn't get **any** response. What's wrong Atlassian Team?

comments: author: minnsey
body: We will be rolling out fix this week.  

I'm afraid <https://jira.atlassian.com> has been hit by huge number of spam issues in recent weeks so we are a bit behind in our triage.


author: Simon_Thom?
body: Thanks Michael
