Minimal zshrc (with less than 30 lines)

source ~/.zplug/init.zsh

zplug "zsh-users/zsh-history-substring-search" # This problem is not related to specific plugin

if zplug check || zplug install; then
  zplug load --verbose
fi

Step to reproduce

1. Install only mawk (no gawk).
2. Empty .zplug/repos
3. Run zsh

% zsh -i                                                                                       [~]
[zplug] Start to install 1 plugins in parallel

 ✘  Unknown error         zsh-users/zsh-history-substring-search

Problem

It seems that zplug is checking awk availability in __zplug::core::core::prepare.

        if ! __zplug::utils::awk::available; then
            __zplug::io::print::f \
                --die \
                --zplug \
                --error \
                'No available AWK variant in your $PATH\n'
            return 1
        fi

But this error does not occur, and "Unknown error" is displayed during installation.

According to the readme, mawk is not supported https://github.com/zplug/zplug/blob/master/README.md#requirements

I solved this by installing gawk: sudo apt install gawk. Hope this helps.

This issue is about error message when proper awk is not installed.

• The error message currently displayed is Unknown error, and there is not enough information to read that the necessary awk is not installed.

• The source code contains a more appropriate error message 'No available AWK variant in your $PATH \n' that seems to have been prepared for this case, but this is not displayed for some reason.

Reproduced this error. It's taken me quite a while to track down this problem. Would be very good if the correct error message mentioned above by @crhg were displayed instead of "Unknown error".
