Installing foundationdb on ubuntu fails

I downloaded foundationdb-server_7.1.33-1_amd64.deb file from releases page on github and trying to install on my ubuntu, I have amd cpu.

(base) ➜  pkg git:(master) ✗ sudo dpkg -i ~/Downloads/foundationdb-server_7.1.33-1_amd64.deb 
dpkg: warning: parsing file '/var/lib/dpkg/' near line 15 package 'foundationdb-server':
 empty value for 'Architecture' field
dpkg: error processing archive /home/elbek/Downloads/foundationdb-server_7.1.33-1_amd64.deb (--install):
 package architecture () does not match system (amd64)
Errors were encountered while processing:
(base) ➜  pkg git:(master) ✗ dpkg --print-architecture

What I am doing wrong?

Thank you!

Nothing, the 7.1.33 debian package is invalid, see 7.1.33 official debian package missing Architecture metadata for amd64

Use 7.1.31 or build from sources.
