Changing Git remote URL updates fetch but not push

From git-remote manual:

set-url    Changes URL remote points to. Sets first URL remote points to matching regex <oldurl> (first URL if no <oldurl> is given) to <newurl>. If <oldurl> doesn’t match any URL,    error occurs and nothing is changed.    With --push, push URLs are manipulated instead of fetch URLs.

So you should additionally execute:

git remote set-url --push origin ssh://user@example.com:XX/package/name.git

As long as the config file for the repo in question contains an entry for the push URL, set-url will only update the fetch URL by default.

[remote "origin"]    url = fetch.git    fetch = ...    pushurl = push.git

As the answer of running.t explains, you can use set-url --push to change this entry. However, you will have to keep doing this every time the URL changes.

To restore the default behavior of set-url (which changes both URLs at once), just delete the entry from the config. Or delete it using set-url --delete:

git remote set-url --delete --push origin push.git

As for why a repository would ever contain a separate push url without you adding it: Some git clients like Sourcetree "helpfully" do this.
