Ah the 416 should be fine if the content range is correct (*/complete size) then apt should realise that it has a complete file.
If there is an issue somewhere else this might need further investigation at a later point. -- 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/1849368 Title: apt-get update issues invalid range requests for previously completed downloads Status in apt package in Ubuntu: New Bug description: When an apt-get update fails, for instance due to a mismatch between the Release and Packages.gz due to a mirror sync/index update, it leaves files in the /var/lib/apt/lists/partial for the distribution: 15466565 16 -rw-r--r-- 1 root root 13860 Oct 22 12:50 /var/lib/apt/lists/partial/ourhost_internal_repo_dists_main_Release 15466663 4 -rw-r--r-- 1 root root 475 Oct 22 12:50 /var/lib/apt/lists/partial/ourhost_internal_repo_dists_main_Release.gpg 15471150 0 -rw-r--r-- 1 root root 0 Oct 22 12:52 /var/lib/apt/lists/partial/ourhost_internal_repo_dists_main_main_binary-amd64_Packages.gz.FAILED In this case both Release and Release.gpg were complete, however when running apt-get update again it issues the revalidation requests for these resources with Range headers that are the length of the file resulting in '416 Requested Range Not Satisfiable': GET .../Release HTTP/1.1 Cache-Control: max-age=0 Accept: text/* Range: bytes=13860- If-Range: Tue, 22 Oct 2019 12:50:05 GMT User-Agent: Debian APT-HTTP/1.3 (1.6.12) HTTP/1.1 416 Requested Range Not Satisfiable It appears: - There's no way for apt-get to know if the file is complete so this logic will always be hit if the file exists https://github.com/Debian/apt/blob/master/methods/http.cc#L956-L962 - The logic for determining whether a server supports range requests is only entered if an Accept-Range header exists, however an absence of this header means support is not available - https://github.com/Debian/apt/blob/master/methods/basehttp.cc#L251 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1849368/+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
