Bug description:
Hello!
I actually tried rustc-1.85, 1.89, 1.84, 1.83, and all of them fail.
Looks like only 1.82 version (cargo-1.82) works and < 1.82 including
default 1.75.
Checked both Ubuntu 22.04 and 24.04. Both are the same.
The problem happens when git-ssh dependencies are used. Looks like
this may be related to incompatibility of cargo and libgit versions.
