I tried the apt provided by focal-proposed. At least sudo apt-get update -eany gave exit status 100, if I disabled networking. Without -eany it gave 0.
I got the source code by 'apt source'. I could not run test-apt-update-failure-propagation: $ sudo ./apt-2.0.5/test/integration/test-apt-update-failure-propagation Cannot find build directory, you might want to set PROJECT_BINARY_DIR E: Looks like the testcases ended prematurely with exitcode: 1 -- 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/1693900 Title: apt-get update should return exit code != 0 on error Status in apt package in Ubuntu: Fix Released Status in apt source package in Xenial: Confirmed Status in apt source package in Bionic: Fix Committed Status in apt source package in Focal: Fix Committed Status in apt source package in Groovy: Fix Committed Status in apt package in Debian: Fix Released Bug description: [Impact] There is no way for scripts to run apt update and be sure that it was entirely successful. We introduce a new flag, --error-on=any that makes apt update also error out on transient errors. [Test plan] We have included a test in the test-suite in test-apt-update-failure-propagation that ensures that warnings become errors. [Where problems could occur] If there's an issue some warnings for transient errors could become errors, or worse I suppose it's possible but unlikely for errors to be reported as warnings... Since the new behavior is behind a flag, regression potential for existing scripts is low if there is no bug. [Original bug report] When running 'apt-get update' (e.g. on a container install post- install script), apt-get return with exit code 0, even so it wasn't able to "update" properly.

They have been ignored, or old ones used instead. It should be corrected to return useful exit code, so that scripts can take the appropriate actions ...
