Bug#982678: systemd: journalctl does not repect SYSTEMD_COLORS=0 - colors are still shown

[Jari Aalto]

Package: systemd
Version: 247.3-1
Severity: minor

PROBLEM:

  env SYSTEMD_COLORS=0 journalctl -xe ssh
  ^[[0;1;31mFailed to add match 'ssh': Invalid argument^[[0m

According to manual page, that should not output any colors:

  man journalctl

       (...)

       $SYSTEMD_COLORS
           The value must be a boolean. Controls whether colorized
           output should be generated. This can be specified to
           override the decision that systemd makes based on $TERM and
           what the console is connected to.
