Additional context
Perhaps it's because cloudflare is blocked in my country, and the problem can be solved by installing a vpn or proxy. But I do not know how to implement it. I will be glad of any help, thanks in advance.

Does your network support IPv6? If not, try to force apt to use IPv4 first:

sudo apt-get -o Acquire::ForceIPv4=true update
sudo apt-get -o Acquire::ForceIPv4=true install cloudflared

Otherwise, if you need a proxy or VPN just to download the package from pkg.cloudflare.com, it is highly likely that your network also blocks the Cloudflare edge IPs. This means that even after you successfully install cloudflared, the service itself will likely fail to establish its outbound connections to the Cloudflare network, hence the cloudflared service traffic (which uses HTTP/2 and QUIC) would also need to be routed through your VPN or proxy.
