aerc binary package in Ubuntu Jammy s390x

 Some of its more interesting features include:
  - Editing emails in an embedded terminal tmux-style, allowing you to check on
    incoming emails and reference other threads while you compose your replies
  - Render HTML emails with an interactive terminal web browser, highlight
    patches with diffs, and browse with an embedded less session
  - Vim-style keybindings and ex-command system, allowing for powerful
    automation at a single keystroke
  - First-class support for working with git & email
  - Open a new tab with a terminal emulator and a shell running for easy access
    to nearby git repos for parallel work
  - Support for multiple accounts, with support for IMAP, Maildir, SMTP, and
    sendmail transfer protocols
  - Asynchronous IMAP support ensures the UI never gets locked up by a flaky
    network, as mutt often does
  - Efficient network usage - aerc only downloads the information which is
    necessary to present the UI, making for a snappy and bandwidth-efficient
    experience 100% free and open source software!
