Of course, the image source is used domestically. Domestic, Tsinghua, University of Science and Technology of China, Ali, NetEase. It's all right.
Although I don't want to be the mirror source of Amway University of Science and Technology here, I have to say that they have a tool that is very easy to use.
Here you just need to choose https access (save the operator to block http) ipv6/ipv4 depending on your protocol support.
However, mobile ipv6 is really problematic. If you don't know, you can choose ipv4
I see the U.S. image source for each version of Debian and Ubuntu. Save yourself the trouble of changing the version every time.
raspberry PI 4B+
Let's take a look at this faction (only 4b+ supports which systems are available)
- openWrt (soft routing)
- Official Debian
- Official Ubuntu server 19.10 (
this is a pit)
- BalenaCloud (Internet of Things, probably and Windows lot that thing connected to azure, like a joke, you think about the domestic network environment, basically lost 90 percent of the packets. The results were found. On this network environment, exploded in situ)
Windows lot(4B not supported) Windows 10 ARM(does not support 4B) this thing 4B + UEFI compatible I have not seen.
- Kodi (TV box, die hard. It's 2020 now. Kodi 2019 domestic plug-ins are basically wasted. Do you still expect kodi not to scientifically access the Internet to work? , but you can also M3U8 PVR stream to see TV)
- Ubuntu Mate (4B is not supported, don't ask, just can't get in.) Didn't fit. No signal for connecting HDMI)
- mozilla iot. (Same joke as Balena, but I didn't configure it, I think Firefox's server can still be used domestically.) But it looks fit. I really don't need it. ）
- NAS (you think about how much you toss, if you are really extremely geeky, then I believe you, you will succeed)
In a word, the official Debian is best used. Others can upset you very much. Too tired to find the information. I had no choice but to burn other OS.
By the way, I found that the recent CF Unicom, the telecom node computer room is very explosive. Access to the home page is weakly prepared to update the next parsing.
