| Mehul | I am following https://help.ubuntu.com/lts/serverguide/kernel-crash-dump.html to enable kernel crash dump for Ubuntu-16.04. I want to automate entire configuration process through shell script, but as mentioned in the above doc, when "apt install kdump-tools" is run, it prompts a dialog asking "Should kdump-tools be enabled by default?". Is there any way to answer any prompted question in "YES" through script? | 05:29 |

| apw | Mehul (N,BFTL), I am sure you can, that is a debconf prompt, and i believe you can pre-answer them as you feel fit. you might ask on #ubuntu-devel they might well know better than me. | 07:39 |
| oSoMoN | re- that libreoffice unit test failure: it’s not just the build that fails, the actual application crashes on x86, see bug #1702165 (and https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=865303) | 09:40 |

| smb | The problem is that the tests we got so far include one that does a simple jsvc run. And I checked this morning on a Xenial 32bit installed VM with the 4.4.0-83 kernel and at least that does work ok. Which puts us back at: what are exactly these java incantations/tests trying to do. | 09:56 |
| LocutusOfBorg | but since the regression seems to be in the kernel, can't we forcebad tests for it? | 10:00 |
| LocutusOfBorg | a lot of stuff will migrate if we exclude that bad test | 10:00 |
| cascardo | I can try running a libreoffice install... that should take less time than the build itself | 11:00 |
| apw | LocutusOfBorg, as we are saying it is likely the kernel is now "right" and anythign which does not work is broken, this might be the wrong approach | 11:24 |

| oSoMoN | smb: that libreoffice crash is happening there: https://cgit.freedesktop.org/libreoffice/core/tree/jvmfwk/plugins/sunmajor/pluginlib/sunjavaplugin.cxx?h=libreoffice-5-3-1#n831. The way LO instantiates a JVM is clearly much more complex than the simple jsvc run | 16:12 |
| smb | oSoMoN, Been watching the Debian side and they found a suspicious piece of code in jdk which might end up trying to use exactly that bigger area of code which is now forbidden (specifically for 32bit) | 16:16 |
| smb | I mean that bigger guard area | 16:16 |

| oSoMoN | aha | 16:19 |
| smb | cascardo, were you looking deeper into that? I was kinda distracted by trying to cope with netplan and my not that simple network setup | 16:21 |
| cascardo | smb: yes, I am looking at that, trying to write a reproducer that would help us understand what is happening | 17:05 |
| cascardo | if not, I have managed to run libreoffice on i386 and get a segfault | 17:06 |
