Comment 1 for bug 1930741

ubuntu-advantage-tools has incorrect syntax in its apt.conf.d snippet; missing the semicolon at the end of the options for the new options introduced recently:

APT::Install::Pre-Invoke {
        "[ ! -f /usr/lib/ubuntu-advantage/apt-esm-hook ] || /usr/lib/ubuntu-advantage/apt-esm-hook pre-invoke || true";
}

AptCli::Hooks::Upgrade {
        "[ ! -f /usr/lib/ubuntu-advantage/apt-esm-json-hook ] || /usr/lib/ubuntu-advantage/apt-esm-json-hook || true";
}

This causes aptdaemon's parser to stumble over it; while apt's is too badly written to notice :)
