Bug Description

While I am generally happy with LTS being stable, oftentimes I find myself in the need to upgrade one package to a more recent version.

Most of the times the version I seek is not included in backports and instead published by individuals or orgs via ppa.

Eventually this version gets included in the second next LTS release, so an alternative to third party sources is to perform a LTS upgrade.

But Ubuntu only supports this LTS version to immediately next LTS release, while I have installed version N and the current version is N+2, so I must perform two upgrades to get that newer package, thus double the effort and time spent.

I wish Ubuntu offered even unsupported a method to skip one intermediary LTS upgrade and allow direct LTS to LTS+2 upgrades, or find a way to provide LTS+2 popular packages to LTS releases.

In my particular case I am struggling with a previously not reported issue of samba that crashes; their wiki asks to reproduce on a maintained version, while my current LTS and even the LTS+1 both ship discontinued versions. I tried running a maintained version from a third party ppa, but that doesn't ship a debugging package containing symbols which are required by upstream when submiting issues. I'd like to avoid getting dirty resorting to the ultimate solution of compiling from source.

deleted two attachments containing kernel logs that were literally only netfilter LOG target which included IP addresses - you should anonymize these in the ubuntu-bug!

also ubuntu-bug only reads dmesg ring buffer which is full of useless netfilter logs, it should read using `journalctl -kb` instead!

sample of correct journalctl method for this machine https://linux-hardware.org/?probe=aa6db2ed41&log=dmesg.1
