在 Raspberry Pi (32-bit) 上安裝 Tor

在 Raspbian (bullseye) 裡面的 Tor 版本太舊 (0.4.5.16-1)：

0.4.5.16-1 (/var/lib/apt/lists/raspbian.raspberrypi.org_raspbian_dists_bullseye_main_binary-armhf_Packages)
 Description Language: 
                 File: /var/lib/apt/lists/raspbian.raspberrypi.org_raspbian_dists_bullseye_main_binary-armhf_Packages
                  MD5: 9106e8e4b3843ebd532ba2b89615a92e
 Description Language: 
                 File: /var/lib/dpkg/status
                  MD5: 9106e8e4b3843ebd532ba2b89615a92e

這個版本試著連上線的時候會發生像是這樣的錯誤訊息：

Oct  4 10:55:58 myserver Tor[991]: http status 400 ("Tor version is insecure or unsupported. Please upgrade!") response from dirserver 1.2.3.4:80. Please correct.

本來想說可以裝 Tor 官方的版本 (官方有提供 apt repository)，結果發現官方不支援 Raspberry Pi 一代用的 armhf 了，只好另外找...

然後翻到「http://raspbian.raspberrypi.org/raspbian/pool/main/t/tor/」這邊有看到新版的 deb 檔案，但拉下來後發現 dependency 需要 libssl3，在 bullseye 上面沒辦法跑。

後來在 Reddit 上翻到有人貼出來的 workaround：「How do I update my TOR relay on a 32-bit armhf bullseye system (Raspberry Pi 3) to the latest version?」，方法是去 Debian 那邊挖 bullseye-backport：「Debian -- Package Download Selection -- tor_0.4.7.13-1~bpo11+1_armhf.deb」。

拉下來以後直接 dpkg -i 幹進去，然後重跑 Tor 看 /var/log/syslog 內容，發現就連上了。

不是最新版 0.4.8.x，但至少能用...？

Ubuntu 改變放掉 i386 的計畫

先前在「Ubuntu 19.10 要放掉 i386 架構」這邊提到 Ubuntu 要放掉 i386 的計畫，因為造成的迴響很大，現在官方決定修改本來的結論：「Statement on 32-bit i386 packages for Ubuntu 19.10 and 20.04 LTS」。

在本來的計畫裡，是完全放生 i386 架構 (完全不管)：

While this means we will not provide 32-bit builds of new upstream versions of libraries, there are a number of ways that 32-bit applications can continue to be made available to users of later Ubuntu releases, as detailed in [4]. We will be working to polish the 32-bit support story over the course of the 19.10 development cycle. To follow the evolution of this support, you can participate in the discourse thread at [5].

現在則是打算透過 container 技術支援 32-bit library & binary，算是某種緩衝方式：

We will also work with the WINE, Ubuntu Studio and gaming communities to use container technology to address the ultimate end of life of 32-bit libraries; it should stay possible to run old applications on newer versions of Ubuntu. Snaps and LXD enable us both to have complete 32-bit environments, and bundled libraries, to solve these issues in the long term.

但應該還是會有程式沒辦法在 container 環境裡跑，看起來官方決定放掉了...
