Description
在 Oracle Linux 9.4 的实验环境中，我们遇到了一个棘手的问题：无法正常使用 dnf 进行软件包管理。以下是详细的故障现象和解决方案。
尝试安装 cmake 时，遇到以下错误。

原因：在某些特定网站上使用 curl 时，不会返回任何输出，而是显示错误消息。当远程端意外关闭 TLS 连接（即未正确关闭）时，Oracle Linux 9 自带的 curl 会失败。
1 2 [shawnyan@ol9 ~]$ curl https://xml-gateway-test.schufa.de curl: (56) OpenSSL SSL_read: error:0A000126:SSL routines::unexpected eof while reading, errno 0
检查确认系统版本和内核信息：
1 2 3 4 5 6 [shawnyan@ol9 ~]$ cat /etc/oracle-release Oracle Linux Server release 9.4 [shawnyan@ol9 ~]$ uname -r 5.15.0-205.149.5.1.el9uek.x86_64 [shawnyan@ol9 ~]$ uname -v #2 SMP Fri Apr 5 11:29:36 PDT 2024
检查 curl 和 openssl 版本：
1 2 3 4 5 6 7 [shawnyan@ol9 ~]$ curl --version curl 7.76.1 (x86_64-redhat-linux-gnu) libcurl/7.76.1 OpenSSL/3.0.7 zlib/1.2.11 brotli/1.0.9 libidn2/2.3.0 libpsl/0.21.1 (+libidn2/2.3.0) libssh/0.10.4/openssl/zlib nghttp2/1.43.0 Release-Date: 2021-04-14 Protocols: dict file ftp ftps gopher gophers http https imap imaps ldap ldaps mqtt pop3 pop3s rtsp scp sftp smb smbs smtp smtps telnet tftp Features: alt-svc AsynchDNS brotli GSS-API HTTP2 HTTPS-proxy IDN IPv6 Kerberos Largefile libz NTLM NTLM_WB PSL SPNEGO SSL TLS-SRP UnixSockets [shawnyan@ol9 ~]$ openssl version OpenSSL 3.0.7 1 Nov 2022 (Library: OpenSSL 3.0.7 1 Nov 2022)
Fix: Upgrade libcurl
解决方案：升级 libcurl，在本地编译安装 curl 源码。
下载 curl 源码
https://github.com/curl/curl/releases/download/curl-7_88_1/curl-7.88.1.zip
编译安装
1 2 3 4 unzip curl-7.88.1.zip cd curl-7.88.1/ ./configure --with-openssl make && make install
声明动态库
1 export LD_LIBRARY_PATH=/usr/local/lib
确认已链接到新版本的 libcurl
1 2 3 4 [root@ol9 ~]# ldd /bin/curl | grep libcurl libcurl.so.4 => /usr/local/lib/libcurl.so.4 (0x00007f73034d6000) [root@ol9 ~]# ll /usr/local/lib/libcurl.so.4 lrwxrwxrwx 1 root root 16 Oct 22 18:31 /usr/local/lib/libcurl.so.4 -> libcurl.so.4.8.0
再次执行 dnf 安装 cmake。
