getting this error when trying to build anchor even tho my rustc version is updated

USER:/mnt/c/solana/program$ anchor build
error: package `solana-program v1.18.15` cannot be built because it requires rustc 1.75.0 or newer, while the currently active rustc version is 1.68.0-dev
Either upgrade to rustc 1.75.0 or newer, or use
cargo update -p [email protected] --precise ver
where `ver` is the latest version of `solana-program` supporting rustc 1.68.0-dev

solana-cli 1.17.25
rustc 1.78.0
rustup 1.27.1
anchor-cli 0.30.

You need to update your solana-cli, you can do so by:

solana-install init 1.18.15

See solana-labs/solana#31428 for an explanation.
