[Bug 2091882] Re: do-release-upgrade too talkative, bloated output

[Julian Andres Klode]

do-release-upgrade automatically starts a screen instance you can attach
to should your SSH connection die, so you can just run it over ssh and
only later attach to your screen. It also runs a 2nd ssh server for you
for emergency access, but of course you could access it over the web
terminal.

It's unclear where we'd run a pager, and the it already runs inside the
screen, so in essence you can just ctrl+a and backscroll already, making
this a bit of a non-issue.

Title:
  do-release-upgrade too talkative, bloated output

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  Hi,

  I'm currently upgrading a cloud machine from 22.04 to 24.04 with do-
  release-upgrade.

  Since upgrading can interrupt the root ssh session the upgrade is
  running on, I am not using an ssh connection, but a virtual console.

  Unfortunately, this web-based virtual console does not support
  scrolling up or down or enlarging the screen, just as physical
  consoles in the old days of 80x25 text screens did.

  The problem:

  do-release-upgrade issues a lot of nice, but talkative and useless
  bloated blah blah, filled with empty lines, when beeing started, to
  make the admin feel good and taken care for.

  But this causes more text to be printed than fits on a console screen,
  and it can't be scrolled up when on a virtual old-style console.

  And this is error prone, since not all printed text can be seen, and
  possibly important hints could have been missed.

  Therefore, do-release-upgrade should either

  - make sure that the output text fits into a 80x25 screen view,
  - or use a pager

  to make sure the admin can read the important stuff.

  regards
