I'm trying to upgrade Ubuntu 18.04 to 20.04. Upgrading stops at:
Preparing to configure libgraphene-1.0-0 (amd64)
while the terminal says:
https://www.adobe.com/products/flashplayer/end-of-life.html?platform_type=Linux&platform_arch=x86_64&browser_dist=Chrome HTTP request sent, awaiting response... Read error (Connection timeout) in headers
It happened for the second time today. When I upgraded a week ago everything was fine.
While I was writing this, upgrading continued after half an hour of waiting, so anyway I'm wondering what was happening.
