I have a game for android and I want to use Unity Remote 5. Far as i know, it needs JDK, so I went to Preferances seen 2 options. First option was the simplest, go to unity hub and install JDK. In unity hub, it is already downloaded the Android pack and i can expend it. When i do so, it appears two components, one is JDK and it is shown unistalled. Here is the problem, I check JDK, I agree terms and conditions, it takes a while to download, but nothing changes. JDK is still unchecked in unity HUB and it is missing in Unity Editor. Here i need help.
I tried the second option, to browse and download myself JDK. It specific that it accept only JDK 8.0, so I install that version, but when i select the file, a warning apears telling it’s not the good version.
The same problem here - when installing Unity version 2019.3.15f1 it does not install OpenJDK. If I use later Add Modules to install it, it again doesn’t work. It looks like installation started, it is doing something for some time and then it stops. Directory on disk is created, but empty.
Seems that no one cares, that it does not work for many people…
Now, installing 2019.4.0f1 with the same result. I found, that problem is, that Unity Hub downloads corrupted version of JDK. In C:\Users<user_name>\AppData\Local\Temp\unityhub-a6579710-aa82-11ea-adf0-cf0a2e35debf\ I had corrupted install file jdk8u172-b11_4be8440cc514099cfe1b50cbc74128f6955cd90fd5afe15ea7be60f832de67b4.zip. It had about 40 MB and it should be about 70 MB.
Also in log (info-log.json) I hed these two lines:
{"moduleName":"DownloadRequest","level":"warn","message":"[ 'Something went wrong while downloading http://download.unity3d.com/download_unity/open-jdk/open-jdk-win-x64/jdk8u172-b11_4be8440cc514099cfe1b50cbc74128f6955cd90fd5afe15ea7be60f832de67b4.zip Error: ESOCKETTIMEDOUT Error: ESOCKETTIMEDOUT\\n at ClientRequest.<anonymous> (D:\\\\Unity Hub\\\\resources\\\\app.asar\\\\node_modules\\\\request\\\\request.js:816:19)\\n at Object.onceWrapper (events.js:282:20)\\n at ClientRequest.emit (events.js:194:13)\\n at ClientRequest.EventEmitter.emit (domain.js:469:20)\\n at Socket.emitRequestTimeout (_http_client.js:673:40)\\n at Object.onceWrapper (events.js:282:20)\\n at Socket.emit (events.js:194:13)\\n at Socket.EventEmitter.emit (domain.js:469:20)\\n at Socket._onTimeout (net.js:429:8)\\n at listOnTimeout (internal/timers.js:535:17)' ]","timestamp":"2020-06-09T18:55:41.694Z"}

I took link to JDK package and downloaded it manually in browser (link is also in info-log.json) file when it logs download start. Browser downloaded first 40MB, then stopped for long time and after while downloaded the rest.
Then I copied this package into Temp directory before Unity installer downloaded other files.
When installation started, it used fixed package and JDK is installed now!
I tired to download JDK package directly once more, this time through Chrome (previously through Firefox). It again stopped ad 40 MB and took more than minute to continue. It simply looks like there is for some reason lag on Unity server side and Unity Hub fires timeout. Browsers seem to be more patient and download it despite the long lags.
