[Bug 1982660] Re: 'foreground=darkred' can make text illegible

[Chris Guiver]

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Please execute the following command only once, as it will automatically
gather debugging information, in a terminal:

apport-collect 1982660

When reporting bugs in the future please use apport by using 'ubuntu-
bug' and the name of the package affected. You can learn more about this
functionality at https://wiki.ubuntu.com/ReportingBugs.

Please note: `ubuntu-bug`, `apport` & bug reporting tools are provided
with Ubuntu by default, many require manual addition for some releases
of downstream OSes based on Ubuntu (eg. Linux Mint). You should check
with your distribution first.

Also be aware the Debian Installer is deprecated in recent releases,
being replaced by `subiquity` (server installs) and `calamares` (flavor
installs no long offer alternate ISOs which is where di was used). It
was supported in focal & earlier but may not be used in future ISOs
having been replaced by subiquity.

Title:
  'foreground=darkred' can make text illegible

Status in debian-installer package in Ubuntu:
  Incomplete

Bug description:
  The Ubuntu release at issue: 22.04 (but also some or all subsequent
  versions?).

  Version of package: unclear or not quite applicable; please see below.

  Expectation: all text in the installer is legible.

  Reality: not all text in the installer is legible.

  Details area as follows.

  To the best of my limited knowledge, the Ubiquity installer can end up
  rendering some text - including some rather important text - in a
  hard-to-read dark red on black. 'To the best of my knowledge' because
  I gather, from a bug report that I filed against Linux Mint, that this
  problem _in some way_ owes to the Ubiquity installer. I attach a
  screenshot that shows the problem.

  The bug report that I mention is here:
  <https://github.com/linuxmint/mint21-beta/issues/79#issuecomment-1193125018>.
  The report describes how, in a version of Ubiquity used by Mint, an
  important warning is very hard to read when using dark mode (and the
  report gives the aforementioned, and here attached, screenshot). In
  responding to the report, the chief maintainer of Linux Mint wrote as
  follows.

  [Start of quotation. Abridgement and interpolation mine.]

  I agree with you. If this was our installer I'd replace this
  foreground=darkred with weight=bold. However this is Ubiquity, the
  pango markups are part of the translations, there are 1729 occurences
  of them in PO files, some taking multiple lines, some using
  backslashes in front of the quotes. I don't want to risk an l10n issue
  just for this or even worse an installer crash. [. . .] This is indeed
  a bug and it should be fixed but the way ubiquity is coded, this isn't
  worth risking a regression [in Linux Mint 21] for.

  [End of quotation.]

  The Mint installer at issue is from Linux Mint 21.0, which is based
  upon Ubuntu 22.04. The Mint installer is hosted at
  <https://github.com/linuxmint/ubiquity>.
