** Description changed: + [Impact] + + * Failing to do error checks on `snap-tool info` calls while determining + the bases of snaps can lead to inconsistently-seeded images as reported + in the original bug report below. + + * This affects all stable releases which use automatic detection of the + base snap during image builds. + + * The changes proposed introduce extra error checking which should + result in a build error, if the `snap-tool info` call fails, thus + preventing distribution of a broken image. + + [Test Case] + + * It may be tricky to reproduce the exact error on demand. But it should + be clear by looking at the code path in + + https://code.launchpad.net/~tobijk/livecd-rootfs/+git/livecd- + rootfs/+merge/370096 + + that the scenario described below may arise. + + * A way to test that the changes have no *negative* impact on + functionality is to run a script such as + + https://pastebin.ubuntu.com/p/wQknctr6ys/ + + and compare it against the expected result + + https://pastebin.ubuntu.com/p/N8PXRJJV9b/ + + (In this case both core and core18 should have been seeded.) and + + [Regression Potential] + + * The regression potential for these changes is low, as they only add + extra error checking but do not change the existing logic. + + --- Original Bug Report --- + Alway fails in both 18.04.2 and 19.04 Reporting the bug failed too yesterday. - As a consequence LivePatch and everything else fails that is based on snapd. + As a consequence LivePatch and everything else fails that is based on snapd.
