8/25 Linux 32 週年生日。

我在MX Linux可以上網，而apt-get update指令能連線到 https://mirrors.ocf.berkeley.edu/ 。
然而，我用apt-get upgrade卻無法連線到 https://mirrors.ocf.berkeley.edu/ ！
請問，我該如何解決這問題？

# 我成功地 apt-get update，系統能連線到 https://mirrors.ocf.berkeley.edu/

PS:
我電腦規格如下：
Operating System: MX Linux 23
KDE Plasma Version: 5.27.5
KDE Frameworks Version: 5.103.0
Qt Version: 5.15.8
Kernel Version: 6.0.0-6mx-amd64 (64-bit)
Graphics Platform: X11
Processors: 12 × AMD Ryzen 5 3600 6-Core Processor
Memory: 31.3 GiB of RAM
Graphics Processor: AMD Radeon RX 570 Series
Manufacturer: ASUS

連線不到,先check幾個點

1. 查 /etc/resolv.conf 設定的指向 , 通常都是指向ISP的DNS Server , 因為我自行架設DNS Server , 所以我的nameserver指向都是127.0.0.1

2. 用 nslookup mirrors.ocf.berkeley.edu 查一下能否正確解析domain name to ip addr.
以下是我的DNS Server解析的結果

[root@server ~]# nslookup mirrors.ocf.berkeley.edu
Server: 127.0.0.1
Address: 127.0.0.1#53

Non-authoritative answer:
mirrors.ocf.berkeley.edu canonical name = fallingrocks.ocf.berkeley.edu.
Name: fallingrocks.ocf.berkeley.edu
Address: 169.229.200.70
Name: fallingrocks.ocf.berkeley.edu
Address: 2607:f140:0:32::70

先確認這兩點,再決定後面如何走!!

謝謝幫忙∼ 我測試結果如下，似乎很正常。

sparc@Mini:~
$ cat /etc/resolv.conf
# Generated by NetworkManager
nameserver 8.8.8.8
nameserver 2001:4860:4860::8888

sparc@Mini:~
$ sudo nslookup mirrors.ocf.berkeley.edu

Plasma 不是主推 wayland 嗎？
話說，Cube effect 要回歸了。

這也只是先確認DNS 解析是正常而已, 既然DNS解析正常,接下來就來確認
能不能access https://mirrors.ocf.berkeley.edu

這個網站,我用chrome可以直接點開 , 您試看看用chrome能不能瀏覽

順便也把 ifconfig -a 及 route -n 也貼一下 ...

PS: 您是不是有用ipv6 ??

謝謝！

1、我在MX Linux的Brave瀏覽器可以開啟 https://mirrors.ocf.berkeley.edu

2、ifconfig -a

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

3、我使用下列的 hosts，所以才會出現0.0.0.0
https://github.com/StevenBlack/hosts
然而，我清空Hosts後，再次apt-get upgrade後，系統還是說 Failed to fetch https://mirrors.ocf.berkeley.edu/

$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.101.1 0.0.0.0 UG 600 0 0 wlan0
192.168.101.0 0.0.0.0 255.255.255.0 U 600 0 0 wlan0

4、我有用ipv6！

看起來,你這台MX Linux 是透過無線網路直接與AP連線 , IPv4 使用的是Private IP
等於是要有一台NAT FW才能連線出去 , 偏偏又使用IPv6 , 所以不確定NAT FW會不會幫
IPv6 做Routing !!

建議你先把IPv6 給Disable , 僅使用IPv4 , 再試看看!!

通常一般user環境下 , 除非你能確定NAT FW本身能做IPv6 Routing , 不然通常我都會建議
不要使用IPv6 (也不要把它給Enable , 這種還境下沒意義,也增加判斷的困難度) !!

對了, /etc/hosts裡也有相關設定嗎 ?? Domain Name直接去指向 ip addr ?? :ase

有試過 MX Repo Manager 嗎？

https://mxlinux.org/wiki/help-files...x-repo-manager/

我過去用 MX Repo Manager 換過Repo，但無效。

我先把IPv6 給Disable , 然後sudo systemctl restart NetworkManager，僅使用IPv4 , 就能成功更新!!

我的/etc/hosts裡將廣|告、收集情報的Domain Name直接指向 ip addr 0.0.0.0!
