Yes, I am. When I download the file myself via firefox, I get a file that matches the hash it is supposed to be and this also matches the file in /var/lib/apt/lists of which the file in /var/lib/apt/lists/partial is merely a symlink.
I ran an ISP transparent proxy test and it came up negative. And the ISP is not involved in DNS at all, because Firefox uses Cloudflare DoH and I'm using Cloudflare DoT otherwise for the system currently. For DNS lookup, I get: ; unsigned answer us.archive.ubuntu.com. 3200171710 IN A 91.189.91.38 us.archive.ubuntu.com. 3200171710 IN A 91.189.91.39 And Firefox is using the latter. (If Ubuntu served these files over https, there would be no possibility of interference by a proxy.) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1880222 Title: ubuntu bionic-backports Hash Sum mismatch Status in apt package in Ubuntu: Incomplete Status in update-manager package in Ubuntu: Incomplete Bug description: # apt-get update (proceeded normally until...)

They have been ignored, or old ones used instead. $ apt-get -v apt 1.6.12ubuntu0.1 (amd64) Also, Software Updater (version 1:18.04.11.12) after hitting "Install" gives pop-up: "Requires installation of untrusted packages This requires installing packages from unauthenticated sources." Only options: "Settings..." and "OK" And it is not OK; I have not configured any unauthenticated sources! This occurs when enabling updates from Ubuntu Base (but not Security updates). I expected to not get such errors and updating to occur normally. $ lsb_release -rd Description: Ubuntu 18.04.4 LTS Release: 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1880222/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
