While building anchor project, I faced the follow error:

"error: package `toml_edit v0.21.1` cannot be built because it requires rustc 1.69 or newer, while the currently active rustc version is 1.68.0-dev Either upgrade to rustc 1.69 or newer, or use cargo update -p [email protected] --precise ver where `ver` is the latest version of `toml_edit` supporting rustc 1.68.0-dev"

My current project is: rustc 1.75.0 (82e1608df 2023-12-21) anchor-cli 0.28.0 solana-cli 1.16.13

I tried solana-install init 1.16.13. But it didnt help me.

I am not sure what the reason and solution of this error.

My OS is ubuntu 22.04. Thanks

solana-install init 1.18.1 

You may also need to upgrade to anchor 0.29.

Similar issue the 1.18.1 fixed here.
