Fix conflicts for git pull using theirs

Command:

git pull

Output:
error: Pull is not possible because you have unmerged files.
hint: Fix them up in the work tree, and then use 'git add/rm <file>'
hint: as appropriate to mark resolution and make a commit.
fatal: Exiting because of an unresolved conflict.

Solution:
git reset --mixed -> this unstage all files that are in conflict
git add -> all the files that you have fixed fo the conflict
git commit
git reset --hard
git merge --strategy=recursive -X theirs origin/master

SOLUTION

1. Update chromedriver manually to the latest version in our case 2.25
sudo webdriver-manager update --versions.chrome 2.25
2. Start webdriver-manager but old chromedriver is used
webdriver-manager start
 I/start - java -jar /usr/local/lib/node_modules/protractor/node_modules/webdriver-manager/selenium/selenium-server-standalone-2.53.1.jar -Djava.security.egd=file:///dev/./urandom -Dwebdriver.chrome.driver=/usr/local/lib/node_modules/protractor/node_modules/webdriver-manager/selenium/chromedriver_2.22

3. update config.json from /usr/local/lib/node_modules/protractor/node_modules/webdriver-manager/built/config.json and update "chromedriver" to be "2.25"
Sample of /usr/local/lib/node_modules/protractor/node_modules/webdriver-manager/built/config.json
{
  "webdriverVersions": {
    "selenium": "2.53.1",
    "chromedriver": "2.25",
    "iedriver": "2.53.1",
    "androidsdk": "24.4.1",
    "appium": "1.5.3"
  },
  "cdnUrls": {
    "selenium": "https://selenium-release.storage.googleapis.com/",
    "chromedriver": "https://chromedriver.storage.googleapis.com/",
    "iedriver": "https://selenium-release.storage.googleapis.com/",
    "androidsdk": "http://dl.google.com/android/"
  }
}

4. Start again "webdriver-manager start" and correct version of chromedriver is used

I/start - java -jar /usr/local/lib/node_modules/protractor/node_modules/webdriver-manager/selenium/selenium-server-standalone-2.53.1.jar -Djava.security.egd=file:///dev/./urandom -Dwebdriver.chrome.driver=/usr/local/lib/node_modules/protractor/node_modules/webdriver-manager/selenium/chromedriver_2.25
