[Bug 2139436] Re: cargo fetch fails with "invalid version 0 on git_proxy_options" error

[Brent Kerby]

@neotryum Would rustc-1.91 work for your use case? This package has the
fix and is now available in Ubuntu 24.04. Because of the Rust
toolchain's backwards compatibility, switching to an updated toolchain
should generally work without issue.

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.
