error: failed to download from `https://crates.io/api/v1/crates/block-buffer/0.10.1/download`
Caused by:
[60] SSL peer certificate or SSH remote key was not OK (SSL certificate problem: unable to get local issuer certificate)
I tried renaming /etc/ssl/certs/ca-certificates.crt which didn't help. I should mention that cargo build works just fine. Only cargo outdated gives above error.
Nevertheless, it must be a local problem as I tried on another Ubuntu system of mine, and there also cargo outdated works fine.
First, I should add that I have installed rust aso. in ~/.cargo using rustup.
I created a new user and installed cargo using rustup, and here cargo outdated works just fine. My guess is that something in ~/.cargo is causing the cargo outdated error.
