Ubuntu 26.04 issue

[Mike20242]

Tried running the install command on latest Ubuntu version (Resolute Raccoon) and it shows these errors:
Could not find official Antigravity 2.0 tarball for linux-x64 in Google download bundle
bash: line 1: tmpdir: unbound variable
How do I fix it?

same issue here in opensuse tumbleweed, looks like download pages changed and it can't extract download URL
