Older version of installer 404'd? (2018.2.6f1)

I tried to use the installer (with sudo ./UnitySetup-2018.2.6f1) on xubuntu and the download 404's. The installer took it's time downloading stuff, but when I went to check the folder I put it in (/opt/unity), nothing was there.

I made sure I had the gtk, libsoup, libarchive dependencies and used the little tutorial in the install thread to do it.

Not sure what the problem is, but I assume the file was just removed off the ftp due to it being an older version? Any help?

 

No, that version should still be accessible.
If things are actually being downloaded, then it can't be a not-found error causing the issue.
Did you get any useful error output in the console?

 

I'm getting a similar error. It seems like no matter the version I try the components list is empty after the installer launches. I get:
Download of 'https://netstorage.unity3d.com/unity/23e0e8b5468d/unity-2018.3.0b2-linux.ini' failed

Any ideas?
