**Apt-cache show only "near-future Sci-Fi roguelike and tactical squad game".**

According with [dists](http://ppa.launchpad.net/qameta/allure/ubuntu/dists/) directory on PPA package exist but [packages information](http://ppa.launchpad.net/qameta/allure/ubuntu/dists/bionic/main/binary-amd64/Packages.xz) is missed(compare with [package for trusty](http://ppa.launchpad.net/qameta/allure/ubuntu/dists/trusty/main/binary-amd64/Packages.gz)). I also don't see package in [pool directory](http://ppa.launchpad.net/qameta/allure/ubuntu/pool/main/a/allure/).

This issue sound's like already exist [Support Ubuntu Bionic (18.04)](https://github.com/allure-framework/allure2/issues/828), but for me it's look like bug created by fix.

Compare the PPA's bionic directory and package metadata with the working trusty entries linked in the issue. Start by checking why the bionic Packages.xz and pool entry are missing, then verify that apt-cache identifies the Allure package rather than the unrelated Ubuntu package and that installation provides the allure command.
