When I try install the package, this error message show up:
Cannot perform upm operation: 101057795:error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac:c:\pkg-fetch\precompile\node\deps\openssl\openssl\ssl\s3_pkt.c:535:
[NotFound]
UnityEditor.EditorApplication:Internal_CallUpdateFunctions()
Restart Unity doesn’t solve the issue. Happens with Unity 2019.1.0f2
Same error happens when tried install Collections package in Unity 2019.4.3f1
Cannot perform upm operation: Unable to add package [com.unity.collections@0.9.0-preview.6]:
One or more dependencies could not be added to the local file system:

I just downloaded package directly from here:
And did “Add package from disk” from Package Manager, but still the same error message appeared.
What happens if you download the burst package directly e.g. go here in a browser: https://download.packages.unity.com/com.unity.burst/-/com.unity.burst-1.4.4.tgz
Also, what OS are you running and do you have any network setup worth mentioning like proxies or firewalls?
Yes, It worked for me by doing turn off firewall in Windows 10
Had the same issue. Disabling firewall resolves the problem.
Also, make sure to quit and restart Unity Hub after disable.
Disable Firewall or Antivirus for some time to install the package.
