Run armbian-config and choose an alternate mirror 

[TRS-80]

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.

[Josephjo]

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

[lanefu]

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

 

[lanefu]

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