关于ubuntu18.04升级内核到6.1.22版本总结

首先按照以下教程直接安装官网的deb，但是出现内核头文件报错无法安装的问题，很多高版本的内核都需要依赖libc6到2.34版本以上，libssl3版本需要3.0.0以上，但这两个系统库网上很难找到安装教程，就此作罢。

然后想到可以从源码编译内核，

按照第一个链接，报错，于是又转到第二个链接，直接修改 .config 文件，把CONFIG_MODULE_SIG_ALL,CONFIG_MODULE_SIG_KEY和CONFIG_SYSTEM_TRUSTED_KEYS三项注释掉，编译时系统会自动生成一次性密钥来加密，另外记得把CONFIG_DEBUG_INFO=y去掉，不然新内核带debug信息超大。

修改后编译，又报了其他错误，错误如下:

make[5]: *** No rule to make target 'debian/canonical-revoked-certs.pem', needed by 'certs/x509_revocation_list'. Stop. scripts/Makefile.build:500: recipe for target 'certs' failed make[4]: *** [certs] Error 2 Makefile:2012: recipe for target '.' failed make[3]: *** [.] Error 2 debian/rules:7: recipe for target 'build-arch' failed make[2]: *** [build-arch] Error 2 dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2 scripts/Makefile.package:76: recipe for target 'deb-pkg' failed make[1]: *** [deb-pkg] Error 2 Makefile:1656: recipe for target 'deb-pkg' failed make: *** [deb-pkg] Error 2

解决办法：

修改后编译，继续报错：

make[4]: *** [vmlinux] Error 1 Makefile:1255: recipe for target 'vmlinux' failed make[3]: *** [vmlinux] Error 2 debian/rules:7: recipe for target 'build-arch' failed make[2]: *** [build-arch] Error 2 dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2 scripts/Makefile.package:76: recipe for target 'deb-pkg' failed make[1]: *** [deb-pkg] Error 2 Makefile:1656: recipe for target 'deb-pkg' failed make: *** [deb-pkg] Error 2

解决办法：

禁用CONFIG_DEBUG_INFO_BTF

修改后编译，编译成功，如图

接下来按照原来的链接开始安装，完美安装成功如图：

立刻重启，检测版本：
