Runs. But it may have undesired side effects for some distributions.

Only shows a white page though; not sure yet why.

When using http rather than https, then it loads.

https://public-cdn.cloud.unity3d.com/hub/prod/UnityHubSetup.AppImage works; what have they done differently?

They are not shipping the problematic libs:

me@host:~$ find /tmp/.mount_UnityHdCJ1L6/ | grep nss
me@host:~$ find /tmp/.mount_UnityHdCJ1L6/ | grep soft

I met the same problem, how did you solve it? @probonopd

[probonopd]

Maybe @azubieta's https://github.com/AppImageCrafters/appimage-builder can solve this.

Regarding the issue, provably some required lib is not being bundled (maybe a plug-in), strace -ff -e trace=file <your binary> may help you find what's being loaded from the system. Once you find it just add it to the bundle.

appimage-builder does embed that lib and many others, it relies on the knowledge contained the Debian/Ubuntu package system to resolve dependencies (reading the needed section of an ELF binary is not enough).

[probonopd]

@liyuzhao Which distribution are you using? Please retry using Ubuntu xenial. Does the problem also exist there?
