Setup

  • Which version of Git for Windows are you using? Is it 32-bit or 64-bit?
$ git --version --build-options

git version 2.20.1.windows.1
cpu: x86_64
built from commit: 7c9fbc07db0e2939b36095df45864b8cda19b64f
sizeof-long: 4

  • Which version of Windows are you running? Vista, 7, 8, 10? Is it 32-bit or 64-bit?
$ cmd.exe /c ver

Microsoft Windows [Version 10.0.17763.253]
  • What options did you set as part of the installation? Or did you choose the
    defaults?
# One of the following:
> type "C:\Program Files\Git\etc\install-options.txt"
> type "C:\Program Files (x86)\Git\etc\install-options.txt"
> type "%USERPROFILE%\AppData\Local\Programs\Git\etc\install-options.txt"

  • Any other interesting things about your environment that might be related
    to the issue you're seeing?

I have PuTTY release 0.70 installed

Details

  • Which terminal/shell are you running Git from? e.g Bash/CMD/PowerShell/other

Bash

git clone ssh://git@bitbucket.linaro.org:7999/its/project-portal-scripts.git
  • What did you expect to occur after running these commands?

I expect the system to use my SSH key hosted in Pageant to authenticate and then clone the repository.

  • What actually happened instead?
Cloning into 'project-portal-scripts'...
plink: unknown option "-p"
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
  • If the problem was occurring with a specific repository, can you provide the
    URL to that repository to help us with testing?

This happens with all of the repositories on bitbucket.linaro.org because of the use of a custom port number.

Syntax output from plink is below - note that to connect to the specified port requires an upper-case P, not a lower-case p as reported in the unknown option error.
