Steam не запускается на Ubuntu 20.04

Недавно переустановил Ubuntu 20.04 и в процессе переустановки некоторых приложений, одним из которых является Steam. Я пробовал выпуск Steam deb и установщик собственного программного обеспечения. При попытке использовать установщик я получаю сообщение: Невозможно установить «Установщик Steam»: следующие пакеты имеют неудовлетворенные пакеты: без отображения пакетов, необходимых для установки. После установки выпуска deb и запуска steam меня приветствует это сообщение об ошибке:

Looks like steam didn't shutdown cleanly, scheduling immediate update check

Любая помощь будет принята с благодарностью. Я некоторое время искал в Интернете, и большинство предлагаемых решений заключается в загрузке и установке пакетов mesa, а также в переименовании или удалении определенных файлов и каталогов lib; ни одно из этих решений не помогло мне. Если кто-нибудь сможет изучить этот своего рода отчет о сбое и помочь мне диагностировать проблему, я был бы очень счастлив. Огромное спасибо!
