Ubuntu 20.04 updated some security policies which has the effect that some connections might not work anymore. This happened for instance with connections to AWS Aurora 5.6 recently. Background AWS Aurora 5.6 only supports TLSv1 for encrypted connection. This TLS protocol version is considered insecure for some time now and has been disabled in Ubuntu 20.04 and MySQL Client 8 respectively. If MySQL configuration permits TLSv1, TLSv1.1, and TLSv1.2, but your host system configuration permits only connections that use TLSv1.
In a recent articleI wrote about the old Raspberry Pi, which serves its duty as my daily Web radio. The Pi MusicBox natively supports a bunch of streaming services, which improves the experience if you already have a streaming account, by providing your custom playlists on any HDMI capable hifi system. Unfortunately, the passwords are stored in plaintext, which is not a recommended practice for sensitive information. Especially if you use your Facebook credentials for services such as Spotify.
The average computer users needs to memorize at least 17 passwordsfor private accounts. Power users need to handle several additional accounts for work too and memorizing (good and complex) passwords quickly becomes a burden if not yet impossible. To overcome the memory issue, there exists a variety of tools, which allow to store passwords and associated metadata in password stores. Typically, a password manager application consists of a password file, which contains the passwords and the metadata in structured form, and an application, assisting the user in decrypting and encrypting the passwords.
