Manjaro 手动降级 AUR 应用
2018-12-31 · 775 chars · 4 min read
平时工作用的笔记本装的 Manjaro 系统，然后公司有一些必须的办公软件并不支持 Linux，所以极其依赖 Virtualbox。就在昨天，看到 yay 提示有软件可升级，随手升了下，悲剧的升级 virtualbox-ext-oracle 时报错，之后发现虚拟机启动不了了：

排查后发现是 virtualbox-ext-oracle 升级到了 6，而 virtualbox v6 依然处在测试阶段：
解决方案只有两个：
- 等 virutalbox 相关应用全部升级到 6
- 手动将 virtualbox-ext-oracle 降级到 5
因为是 virtualbox 中跑的 windows 7 系统是日常必备的，所以没辙，只能手动降级。
downgrade#
首先想到的就是 downgrade，使用 downgrade 降级十分简单，以 firefox 为例，执行 DOWNGRADE_FROM_ALA=1 downgrade firefox ：
$ DOWNGRADE_FROM_ALA=1 downgrade firefox Downgrading from A.L.A. is disabled on the stable branch. To override this behavior, set DOWNGRADE_FROM_ALA to 1 . See https://wiki.manjaro.org/index.php?title=Using_Downgrade for more details. Available packages: 1) firefox-64.0-1-x86_64.pkg.tar.xz (remote) * 2) firefox-64.0-0-x86_64.pkg.tar.xz (local) * 3) firefox-63.0.3-1-x86_64.pkg.tar.xz (remote) * 4) firefox-63.0.3-1-x86_64.pkg.tar.xz (local) * 5) firefox-63.0.3-0-x86_64.pkg.tar.xz (local) * 6) firefox-63.0.1-1-x86_64.pkg.tar.xz (remote) * 7) firefox-63.0.1-1-x86_64.pkg.tar.xz (local) 8) firefox-63.0-2-x86_64.pkg.tar.xz (remote) * 9) firefox-63.0-1-x86_64.pkg.tar.xz (remote) * 10) firefox-63.0-1-x86_64.pkg.tar.xz (local) * 11) firefox-63.0-0-x86_64.pkg.tar.xz (local) 12) firefox-62.0.3-2-x86_64.pkg.tar.xz (remote) * 13) firefox-62.0.3-1-x86_64.pkg.tar.xz (remote) * 14) firefox-62.0.3-1-x86_64.pkg.tar.xz (local) * 15) firefox-62.0.3-0-x86_64.pkg.tar.xz (local) 16) firefox-62.0.2-1-x86_64.pkg.tar.xz (remote) * 17) firefox-62.0.2-0-x86_64.pkg.tar.xz (local) * 18) firefox-62.0-1-x86_64.pkg.tar.xz (remote) * 19) firefox-62.0-1-x86_64.pkg.tar.xz (local) * 20) firefox-62.0-0-x86_64.pkg.tar.xz (local) * 21) firefox-61.0.2-1-x86_64.pkg.tar.xz (remote) * 22) firefox-61.0.2-1-x86_64.pkg.tar.xz (local) 23) firefox-61.0.1-2-x86_64.pkg.tar.xz (remote) * 24) firefox-61.0.1-1-x86_64.pkg.tar.xz (remote) * 25) firefox-61.0.1-1-x86_64.pkg.tar.xz (local) * 26) firefox-61.0-1-x86_64.pkg.tar.xz (remote) * 27) firefox-60.0.2-1-x86_64.pkg.tar.xz (remote) * 28) firefox-60.0.1-1-x86_64.pkg.tar.xz (remote) 29) firefox-60.0-1-x86_64.pkg.tar.xz (remote) 30) firefox-59.0.2-3-x86_64.pkg.tar.xz (remote) select a package by number:
选择一个版本安装即可，然后 downgrade 并不是任何时候都有效，例如我现在想降级的 virtualbox-ext-oracle 就不行。下面是 downgrade 的介绍
It is a very easy to use terminal program that enables you to downgrade packages from your system cache or from the Arch Linux Archive – A.L.A (formally the Arch Linux Rollback Machine – A.R.M) database.
而 virtualbox-ext-oracle 是 ARU 软件
手动降级#
首先找到 virtualbox-ext-oracle 的 git 仓库：
clone 下来后，查看 git log：
* 424217e - (2 days ago) commit virtualbox-ext-oracle 6.0.0-1 - Christian Hesse (origin/master, origin/HEAD, master) * 495258d - (7 weeks ago) commit virtualbox-ext-oracle 5.2.22-1 - Christian Hesse (HEAD) * 10d3b74 - (2 months ago) commit virtualbox-ext-oracle 5.2.20-1 - Christian Hesse * 21fc976 - (5 months ago) commit virtualbox-ext-oracle 5.2.18-1 - Christian Hesse * 05cc4fb - (5 months ago) commit virtualbox-ext-oracle 5.2.10-1 - Christian Hesse * a3cb846 - (6 months ago) commit virtualbox-ext-oracle 5.2.10-1 - Christian Hesse * 4672c55 - (8 months ago) commit virtualbox-ext-oracle 5.2.12-1 - Christian Hesse * 8f463cf - (9 months ago) commit virtualbox-ext-oracle 5.2.10-1 - Christian Hesse * 142e487 - (10 months ago) commit virtualbox-ext-oracle 5.2.8-1 - Christian Hesse * 5d991fb - (12 months ago) Bump 5.2.6 (really this time, fix typo) - Christian Hesse
checkout 到 5.2.22-1 这个 commit，然后执行 makepkg :
之后就可以在当前目录下看到 virtualbox-ext-oracle-5.2.22-1-any.pkg.tar.xz 文件。
卸载掉 virtualbox-ext-oracle 6
sudo pacman -Rsn virtualbox-ext-oracle
然后直接安装 virtualbox-ext-oracle-5.2.22-1-any.pkg.tar.xz 即可：
sudo pacman -U virtualbox-ext-oracle-5.2.22-1-any.pkg.tar.xz
