Over the past two days, I've noted that https://packages.ubuntu.com/ has been having a couple of issues. Currently this question is looking for a package which should exists in xenial (libasm-java) and does exist in trusty and bionic.

I would tell the OP where to download the .deb file from directly, but cannot find a good link...

  • This any help??? – Fabby Feb 13 '19 at 20:13
  • No we don't have one canonical answer/question combo because of the insane multitude of potential problem causes, esp. when you start going to country mirror levels. – Thomas Ward Feb 13 '19 at 20:24

I think this is a package-specific issue, something to do with libasm-java not existing in Xenial. There might be a reason, and there may be a way to step around this specific problem.

That said, I have submitted a rather generic answer about what I would do. Essentially torturing and executing every package blocking the upgrade. Once I'm on the other side, just reinstall what I need. It requires an amount of technical confidence and there are cases where you would not want to follow it blindly.

I wouldn't suggest it's canonical. As Thomas said in the comments, I think there is just a bit too much variation out there to suggest one way of doing things.

  • Thanks Oli - This one seems strange to me because the libbluray-bdj exists both before and after xenial, but the dependencies are not the same between Ubuntu versions - Trust does not require libasm, Xenial requires libasm4-java, and Bionic requires libasm-java... Personally I just reinstall rather than update, but again I'm a little lazy! – Charles Green Feb 14 '19 at 15:44
  • Yeah I'll happily concede there is something weird going on. It might be temporary, it's probably worth a bug report, but for the purposes of a release-upgrade it's easily remedied. – Oli Feb 15 '19 at 9:59
