RPM dependency `fuse2-libs` is unavailable on Fedora 44

RPM dependency fuse2-libs is unavailable on Fedora 44

Environment

• OS: Fedora 44
• Architecture: x86_64
• Tuttle: 4.2.1
• Package: Tuttle-4.2.1-Linux-x86_64.rpm

Problem

Installing the RPM on Fedora 44 fails because the package declares a dependency on fuse2-libs:

Error:
 Problem: conflicting requests
  - nothing provides fuse2-libs needed by Tuttle-4.2.1-1.x86_64

I checked the RPM metadata with:

rpm -qpR ./Tuttle-4.2.1-Linux-x86_64.rpm | grep -i fuse

which reports:

fuse2-libs

However, Fedora 44 provides the FUSE 2 library through the fuse-libs package:

rpm -q --provides fuse-libs | grep -i fuse

which includes:

fuse-libs = 2.9.9-25.fc44
fuse-libs(x86-64) = 2.9.9-25.fc44
libfuse.so.2()(64bit)

I also traced the dependency to ui/package.json, where the RPM configuration currently specifies:

"rpm": {
  "depends": [
    "zlib",
    "fuse2-libs"
  ]
}

The dependency appears to have been introduced in commit 0b706cc53c765d6cfbf6db8f32c08f80f3bc22c9 as part of the Linux packaging changes.

Question

Is fuse2-libs intentionally required for the RPM package?

If so, is there a recommended way for Fedora users to satisfy this dependency?

If Fedora's fuse-libs package provides the required FUSE 2 ABI, would it be appropriate to change the RPM dependency, or is there a more portable RPM dependency/capability that should be used to support multiple RPM-based distributions?

I haven't made any changes yet because I wanted to confirm the intended packaging approach first.

@ARUNMANIKANDAN-C thanks for raising this issue. What I can contribute to Linux distribution issues is quite limited. I have recently successfully installed the app (app image) my own Asahi Linux (arm64). The dependency may have been required to make this work. I would appreciate more input from the Linux user community to resolve this.

[ARUNMANIKANDAN-C]

Thanks! I'd be happy to investigate this. I've confirmed on Fedora 44 that fuse-libs provides the FUSE 2 ABI (libfuse.so.2), while the current RPM explicitly requires fuse2-libs. I'll look into whether the application actually requires libfuse.so.2 and whether using the RPM capability rather than a distribution-specific package name would provide a more portable solution. I'll test the packaging change on Fedora 44 before proposing a PR.

Thanks @ARUNMANIKANDAN-C. Do we need additional testing, CI/CD infrastructure etc. to ensure compatibility with various Linux distributions?

[ARUNMANIKANDAN-C]

@clstaudt Yes, additional CI/CD testing would be useful. The RPM should be tested across major RPM-based distributions, including Fedora, RHEL/CentOS/Rocky/AlmaLinux, and openSUSE, since dependency names and availability can differ between them.

[ARUNMANIKANDAN-C]

Hi, I’ve checked the root cause of the fuse2-libs dependency issue on Fedora/RHEL-based Linux distributions and updated the necessary RPM dependencies required for Tuttle to run correctly. The changes have also been tested on Fedora 44.
