Could you try to log in to your site via FTP or CPanel, and delete the existing Jetpack plugin folder, and reinstall the plugin manually as explained here:

You’ll find the Jetpack plugin folder here:
wp-content
plugins
jetpack - DELETE THIS FOLDER
If you’re not sure how to do this, you can ask your hosting company for help. They should also have documentation explaining how to edit or remove files from your site using FTP or a File Manager in your admin panel.
Let me know how it goes.
Thank you so much.
I was successfully able to delete the Jetpack folder using FTP and then I did a reinstall with no problem.
I am now having the same problem going from Jetpack 4.2.1. to 4.2.2. 🙂
I don’t think it’s the plugin though.
This afternoon I tried updating another plugin, AMP by Automattic, as well as Jetpack. I am using version 4.6 of WordPress. I think its my version of WordPress that is not allowing me to update plugins in the usual manner?
Thanks for any suggestions that you may have.

It could be, if you’re running an old version of WordPress.
The problem could also be linked by your server configuration, or the amount of resources available on that server.
If this keeps happening on future releases and for multiple plugins, I’d recommend getting in touch with your hosting provider and letting them know about the issue. They might be able to help you with this.
