I trying to update my orange pi4 armbian.

 

this error occur after all the ubuntu arm source are upgraded. I check the source.list there aren't these links?

Run armbian-config and choose an alternate mirror 

Do you have apt-transport-https installed?

 

$ dpkg-query -l apt-transport-https

 

And/or try again in few minutes?

 

But what lanefu said might be better advice, he knows more about it than me.

anyway I think i solve it using sudo apt-get upgrade --fix-missing

@Josephjo I had also connect problems via apt to https://mirrors.nju.edu.cn
and changed via armbian-config to the EU-Mirros - problem for armbian update was solved for me....

 

But it seems that the problem is more via apt then via a webbrowser, because in the webbroswer I (mostly) have no problem to connect to https://mirrors.nju.edu.cn

you can manually edit your mirror to use http.. but yeah some of the asian mirrors can be un predicatable

 

If any pythonistas wanna help add support to persist http and https request with the redirect tool that'd be great
