Hi Vegeta,

I suggest following the instructions from this article. The main point is that you need to find this exact expired key and renew it using the apt-key command.

Let me know whether it worked out for you.

Liudmila, thank you and got it to work with an additional step, for anyone who would find this:

E: Repository ‘Index of /raspbian buster InRelease’ changed its ‘Suite’ value from ‘stable’ to ‘oldstable’
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.

Hi Vegeta,

Glad to hear that you found a complete solution for your case! I hope it will work for the users that faced the same issue too.
