Gentoo更新portage记录
2024-05-20 10:45:23
小记一下这两天更新服务器版本遇到的各种问题。
服务器系统： Gentoo
第一天
其实本来不打算更新系统的，因为最近想试试免费的SSL证书，于是自然而然搜到了letsencrypt，跟着他们的流程需要安装
$ sudo emerge -av app-crypt/certbot app-crypt/certbot-nginx
运行了下，结果给出的错误是：
!!! The following installed packages are masked: - sys-devel/gcc-4.4.5::gentoo (masked by: package.mask) /usr/portage/profiles/package.mask: # Michał Górny <mgorny@gentoo.org>, Andreas K.

看到这个错误我还是懵的状态，不懂什么意思，然后网上一通乱搜之后，糊里糊涂的觉得是不是应该更新一下portage树，于是运行如下命令：
$ sudo emerge --sync $ sudo emerge --depclean $ sudo emerge --update --newuse --deep --with-bdeps=y @world
前两个命令没有报错，最后一个命令肯定是没成功的，但是的错误信息跟之前的类似，意思就是要我去更新Protage版本。
第二天
又开始来折腾了，我这不达目的不罢休的精神也是可嘉。
网上开始搜索如何更新portage
$ sudo emerge -1v portage
打开man emerge, -l 的选项意思如下
--changelog (-l)
Use this in conjunction with the --pretend option. This will show the
ChangeLog entries for all the packages that will be upgraded.
上面命令的结果还是关于 EAPI
!!! Repository 'x-portage' is missing masters attribute in '/usr/local/portage/metadata/layout.conf' !!! Set 'masters = gentoo' in this file for future compatibility* IMPORTANT: 5 news items need reading for repository 'gentoo'.* Use eselect news read to view new items.These are the packages that would be merged, in order:Calculating dependencies... done!!!! All ebuilds that could satisfy "app-eselect/eselect-pinentry" have been masked. !!! One of the following masked packages is required to complete your request: - app-eselect/eselect-pinentry-0.7::gentoo (masked by: EAPI 7)The current version of portage supports EAPI '6'. You must upgrade to a newer version of portage before EAPI masked packages can be installed. (dependency required by "app-crypt/pinentry-1.1.0-r2::gentoo" [ebuild]) (dependency required by "app-crypt/gnupg-2.2.10::gentoo" [ebuild]) (dependency required by "sys-apps/portage-2.3.51-r1::gentoo[-build,rsync-verify]" [ebuild]) (dependency required by "portage" [argument]) For more information, see the MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook.
参考了https://forums.gentoo.org/viewtopic-t-1087032.html?sid=fc9d72cb8cbb9deac2142bfa542cc06f，照着运行了下面四个命令
sudo emerge --sync sudo emerge -qav python sudo USE='-rsync-verify' emerge -qavO portage sudo emerge -qav portage
第一个命令没有什么知道参考的结果，下面从第二个命令开始
$ sudo emerge -qav python
这一步虽然有warning消息提示我有几个package被masked了，但是最终python还是安装成功了，结果如下：

然后运行

上面的错误信息我先关注到的点是：
!!! The following installed packages are masked: - sys-libs/glibc-2.25-r10::gentoo (masked by: package.mask)
mask的意思如下：
package.mask
The package.mask file primarily blocks the use of packages that cause
problems or are known to have issues on different systems. It resides
in /usr/portage/profiles.
所以可能是这个包太旧了，过期了，所以我就更新了这个包

红色标注的话意思是想要安装的包被 sys-devel/bison-2.7 给阻塞了，所以我打算先更新 sys-devel/bison
sudo emerge sys-devel/bison
上面命令运行没报错，bison更新完了，那再次更新 glibc
sudo emerge sys-libs/glibc
?glibc也更新成功了, 感觉离成功不远啦！
Note: 更新完glibc，要记得去重启cron，不然会cronjob会如下错误：

跟刚才的错误消息类似，glibc包的错误没有了，但是gcc的错误依然在：
- sys-devel/gcc-4.5.4::gentoo (masked by: package.mask)
那就更新 gcc吧，运行了命令：
sudo emerge sys-devel/gcc
这个命令运行了很久很久~~~
最后成功了安装了gcc的最新版本 sys-devel/gcc-7.3.0-r3
再次运行
sudo emerge -qav portage
然而结果还是跟没安装gcc之前一样，没有变化。
查看gss版本：
emerge -p --depclean sys-devel/gcc
结果如下
Calculating dependencies... done! >>> Calculating removal order...>>> These are the packages that would be unmerged:sys-devel/gccselected: 4.5.4 4.8.5 5.4.0-r3 6.4.0-r1 protected: none omitted: 7.3.0-r3 All selected packages: =sys-devel/gcc-5.4.0-r3 =sys-devel/gcc-4.8.5 =sys-devel/gcc-6.4.0-r1 =sys-devel/gcc-4.5.4>>> 'Selected' packages are slated for removal. >>> 'Protected' and 'omitted' packages will not be removed.Packages installed: 361 Packages in world: 85 Packages in system: 43 Required packages: 357 Number to remove: 4
没辙了，毅然决然删除旧版本gcc
sudo emerge -C sys-devel/gcc-4.5.4 sudo emerge -C sys-devel/gcc-4.8.5
成功删除！
再再再次运行
sudo emerge -qav portage
恩，这下结果有变，gcc的错误没有了

这下改更新binutils了
sudo emerge sys-devel/binutils
binutils从 2.29.1-r1 更新到 2.30-r4，下面就删除旧版本
sudo emerge -C sys-devel/binutils-2.29.1-r1
再再再再次运行
sudo emerge -qav portage
这下错误信息只剩一种了：

这个里面的重点错误消息是：
!!! Multiple package instances within a single package slot have been pulled !!! into the dependency graph, resulting in a slot conflict:
于是google了第一句出错消息，果然有很多人遇到类似情况，看着大家建议更新标注的那些包, 我这边就是 dev-python/setuptools:0 和 dev-python/certifi:0
于是乎就一一更新
sudo emerge dev-python/setuptools
运行结果跟上一个命令 ` sudo emerge -qav portage ` 一样，没有变化。
傻傻又更新一次另外一个包:
sudo emerge dev-python/certifi
还是同样结果~~
不能放弃，眼看就要成功了！
又google了下，运行
sudo emerge --ask --oneshot dev-python/setuptools-30.4.0 dev-python/certifi-2016.9.26
提示如下，这个错误有点low：
!!! 'dev-python/setuptools-30.4.0' is not a valid package atom. !!! Please check ebuild(5) for full details.
我有点病急乱投医了，整个过程都是在尝试，尝试。
恩，再试，更新 setuptools
sudo emerge -u dev-python/setuptools

哇，竟然没有错误了，这么神奇
再再再再再运行那个万恶之源的命令
