instalation via cargo does not work for me in ubuntu 20.04

[aemiranda7]

After doing all steps that were mentioned in the ubuntu 20.04 and when i do cargo install rdedup the instaltion gives the folowing error: Updating crates.io index Installing rdedup v3.1.1 error: failed to compile rdedup v3.1.1, intermediate artifacts can be found at /tmp/cargo-installxHlhJS

Caused by: failed to select a version for the requirement crypto-mac = "^0.5" candidate versions found which didn't match: 0.11.1, 0.11.0, 0.10.1, ... location searched: crates.io index required by package blake2 v0.7.0 ... which is depended on by rdedup-lib v3.1.0 ... which is depended on by rdedup v3.1.1

:S

Some yanked dep versions probably. Some dependency updates are going to be required.

[dimitarvp]

Exactly the same here on latest macOS and stable Rust. You might indeed have to bump your dependency versions a bit.

Really want to start using rdedup. 😃 It would be nice if you fix the build.

[dpc]

Please help, fill a PR. :pray:

The strange thing is I am able to build from the source code locally.

rdedup on  master is 📦 v3.1.1 via 🦀 v1.54.0
❯ ./target/debug/rdedup --version
rdedup

I think we should make a new release.

Update 1:

Even though I can build the binary, it can't be installed.

I've published v3.2.0

I am using sccache though, I'll check if it builds fine without it.

[dimitarvp]

Nope, the same problem is present when disabling sccache as well (and emptying its cache).

@dpc Any suggestions how to further troubleshoot this?

[dimitarvp]

Looking at @azzamsa's comment above, I tried building rdedup locally (after a git clone). It succeeded. cargo install --path . did indeed fail with the same error as above however.

If that helps, here are the contents of my ~/.cargo/config:

[build]
rustflags=["-C", "target-cpu=native"]

[profile.dev]
split-debuginfo = "unpacked"

[dpc]

Published v3.2.1 . clap version was pinned to beta2 and resolution of version between clap and clap_derive went wrong. When building locally for some reason this is not happeniung.

[dimitarvp]

Yep, now it installed correctly through cargo install rdedup. Thanks!
