i am new in fedora, today i installed and all work fine, but when i update the system with:
sudo dnf update
i reboot my computer and after that i cant enter in https://github.com/ but all others pages works.
Hi, Michel, and welcome to the forum. Sorry to hear you are having this issue.
Since all other sites work, the first thing I’d be checking is to see if github.com is down, as indicated. I’d try
curl https://github.com, I’d try
ping github.com, I’d try using a different device or browser.
If other devices can access that site but not this Fedora system, then I’d start poking at this system. I’d try
nslookup github.com to see if this system knows how to reach it.
Have you tried any of these, and if so, with what results?
When pasting command results in, please use the </> button to ensure the formatting is readable. And for
curl output, which if successful will be rather long, just show the first and last few lines, please.
Thks to helpme,
i can enter with others pc and phones in the same red.
I tryed with chrome and firefox with fedora but i cant do it after the update of the system.
imutes@fedora ~ nslookup github.com Server: 127.0.0.53 Address: 127.0.0.53#53
✘ imutes@fedora ~ ping github.com ping: github.com: Name or service not known
imutes@fedora ~ curl github.com curl: (6) Could not resolve host: github.com
Interesting. So the issue here is that the system’s DNS lookup of this address fails. Do you have any failed services?
systemctl status In particular you should check systemd-resolved. Oh, and is this Fedora 35? Also please show the output of
Have you modified /etc/hosts?
Yes, i am using Fedora 35.
I didnt change host.
I only install fedora 35, later install zsh and ho my zsh.
Later sudo dnf update and it break my system.

and my host file

Can you resolve
github.com by using another DNS resolver. Try:
nslookup github.com 22.214.171.124
126.96.36.199 part to a well-known DNS resolver as you wish.
thanks you a lot, works
