Question I can't install the Unity on Linux Mint... (Cause of some random internet problem)

So, i had the Unity Hub Installed on my Linux Mint 21, and when i try to install a Unity Editor version, it shows me: "The Hub is unable to load Editor versions. Please check your Internet connection." (and i clicked the button where it said "Try Again" but it did not work.)

i have internet connection on my browser, i had disconnected and reconnected to wifi, i had already reseted my pc, i have installed unity without it (but it sent me some "license error" cause i had my free personal license on my unity hub...), and i had uninstalled and reinstalled my Unity Hub but it still did not work...

... is there any solution for that?

 

I'm using Ubuntu, and have the exact same issue...
I just installed UnityHub on new ubuntu installation and when I try installing editor I get "The Hub is unable to load Editor versions. Please check your Internet connection"
can't be the internet connection... when I click on learn tab.. it shows tutorials I can click on and get to on the Unity learn...

 

Experiencing the same here.

Ubuntu MATE 22.04
Unity Hub 3.5.0

Interestingly, the same version of Unity Hub on two other Ubuntu MATE machines on the same network have no issue connecting. Have not figured out the root cause yet, but will update if I do.

A workaround that did the trick for me was to open a project, and click on the missing editor warning and install from the resulting popup. Hopefully this helps somebody in the meantime.

Very odd issue...

 

The workaround I ended up with was SCP the editors from old machine /Unity/Hub/Editors/ to the new machine and then instead of 'install editor' I used 'Locate' navigated into the editors folders til I found 'unity'

 

Update: I'm able to install from the archives, choosing the Hub option there.

I'm facing the same issue on Pop OS 22.04. I tried installing the PopShop version of the Hub and also using the method mentioned here:

https://gist.github.com/bladeSk/0fd443f9721f222551e0ed2611681c1a

Both have the same issue. I'm able to open the Hub and sign in and activate license properly. The only problem is not able to view or install any editor.

The Hub is unable to load Editor versions. Please check your Internet connection.

These are the last couple of logs I get when I click on the Install Editor button:

I don't have any firewall installed and I'm not behind a proxy.

 

So here is something interesting: I was having a few more weird network-related issues and tracked them down to my wifi card's power-save mode, which NetworkManager will enable by default. When I fixed that, Unity Hub suddenly started working for me as well. If you're on a flavor of Ubuntu you should be able to check like so:

Code (csharp):

1. sudo vim /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Change the value

Code (csharp):

1. wifi.powersave = 2

This will disable powersave altogether. After updating the conf file, NetworkManager needs to be restarted.

Code (csharp):

1. sudo systemctl restart NetworkManager

Not 100% sure this'll work for everyone, but figured I would come back and drop it here.
