Cannot upgrade dfx

I tried to upgrade from 0.6.26 to 0.7 with dfx upgrade but ran into this error message:

Current version: 0.6.26
Fetching manifest
Invalid data: unable to fetch manifest: Forbidden

Can someone help?

This worked for me.

DFX_VERSION=0.7.0 sh -ci "$(curl -fsSL"

Found out where the issue was. I was trying to upgrade dfx in a subfolder path. When I returned to the parent folder and ran dfx upgrade again, it worked out just fine.
