[Bug] 在 Fedora 43 Workstation 上安装 Forge 失败

问题描述 | Bug Description

问题

在最近发布的 Fedora 43 workstation 上安装 mc 1.20.1 + forge 任意版本都会失败，错误信息为哈希不正确：

猜测原因

该发行版预装 zlib-ng 提供 deflate 压缩算法实现，而不是 zlib 官方库。该库以性能著称，但是输出的压缩数据与官方库不同，而 hmcl 正是通过对比 forge installer 内清单提供的哈希和安装完成后输出 jar 的哈希来校验安装结果，因而误判了安装失败。

HMCL/HMCLCore/src/main/java/org/jackhuang/hmcl/download/forge/ForgeNewInstallTask.java

Lines 155 to 174 in da5bbd2

	LOG.info("Executing external processor " + processor.getJar().toString() + ", command line: " + new CommandBuilder().addAll(command).toString());
	int exitCode = SystemUtils.callExternalProcess(command);
	if (exitCode != 0)
	throw new IOException("Game processor exited abnormally with code " + exitCode);
	for (Map.Entry<String, String> entry : outputs.entrySet()) {
	Path artifact = Paths.get(entry.getKey());
	if (!Files.isRegularFile(artifact))
	throw new FileNotFoundException("File missing: " + artifact);
	String code;
	try (InputStream stream = Files.newInputStream(artifact)) {
	code = DigestUtils.digestToString("SHA-1", stream);
	}
	if (!Objects.equals(code, entry.getValue())) {
	Files.delete(artifact);
	throw new ChecksumMismatchException("SHA-1", entry.getValue(), code);
	}
	}

此外，forge 官方也遇到过类似的问题 MinecraftForge/Installer#77

HMCL 不会调用系统的解压缩工具来处理压缩包，你需要提供完整的启动器日志。

一般来说，该问题由 Lex 更改历史发行版 且 镜像源同步不及时 导致。
