• VSCode Version: 1.25.1
• OS Version: Ubuntu 16.04.4 amd64

Steps to Reproduce:

1. Run:

git init --bare origin
git init --bare upstream
git clone origin clone
cd clone
git remote add upstream $(readlink -f ../upstream)
touch hello.txt
git add hello.txt
git commit -m "Initial Commit"
git checkout -b hello-text
echo 'Hello, World!' > hello.txt
git add hello.txt
git commit -m 'Add Hello, World! text'
git checkout master
git push -u origin master
git push -u origin hello-text
git push upstream master
git push upstream hello-text
git branch -D hello-text
code .

2. Execute Git: Checkout to... on origin/hello-text.
3. You get an error Git: pathspec 'hello-text' did not match any file(s) known to git..

The cause is VS Code running: git checkout q <branch-name>, which only works when the branch exists in exactly one remote (See git-checkout(1)), instead of something like: git checkout -q -t <remote>/<branch> , or any alternative more verbose/explicit git checkout command.

Does this issue occur when all extensions are disabled?: Yes
