Chipiri chapfuura, Canonical yakakanda itsva kernel shanduro dzeUbuntu 19.04 uye Ubuntu 18.04. Kunyangwe chikamu cheicho chakaburitsirwa Bionic Beaver chakaendeswawo kuXenial Xerus, iyo vhezheni yeUbuntu yakaburitswa muna Kubvumbi 2016 yakanga isati yawana imwe vhezheni, kusvika nhasi: iyo kambani inomhanya naMark Shuttleworth yaburitsawo kernel kugadzirisa kweUbuntu 16.04 kugadzirisa zvikanganiso zvitanhatu, chimwe chazvo kubva 2018 uye hapana chakanyanya kukomba.
Kusiyana neshanduro dzakaburitswa musi wa23, zvakaburitswa nezuro zvinongowanikwa kune vashandisi veUbuntu 16.04, kunyanya avo vachiri kushandisa iyo Linux 4.4 kernel. Vashandisi vakagadziridza kune yemberi vhezheni yeUbuntu kana kernel yayo haina kukanganiswa. Izvi ndizvo zvakagadziriswa neshanduro nyowani.
