Hello,  
my Rocket.Chat server looks like this:

### Server Setup Information

- Version of Rocket.Chat Server: 3.6.0
- Operating System: Ubuntu 18.04 LTS
- Deployment Method: tar
- Number of Running Instances: 1
- NodeJS Version: 12.22.1
- npm: 6.14.12
- MongoDB Version: 3.6.3

I try to upgrade my Rocket.Chat to `version 4.1.1` because it has the same requirements as mine, according this document [Updating Rocket.Chat - Rocket.Chat Docs](https://docs.rocket.chat/deploy/deploy-rocket.chat/updating-rocket.chat).

There is a step  
`cd /tmp/bundle/programs/server && npm install`

when I execute command `npm install` I get

```auto
npm WARN deprecated node-pre-gyp@0.14.0: Please upgrade to @mapbox/node-pre-gyp: the non-scoped node-pre-gyp package is deprecated and only the @mapbox scoped package will recieve updates in the future
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142
npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm WARN deprecated uuid@3.4.0: Please upgrade to version 7 or higher. Older versions may use Math.random() in certain circumstances, which is known to be problematic. See https://v8.dev/blog/math-random for details.

Could you help me to fix this problem?
