Linux Mint 21.1 “Vera” is a significant release that includes many new features and improvements. The Cinnamon desktop environment has been updated to version 5.6, bringing numerous performance and stability improvements and introducing a convenient new ISO verification tool – conveniently located in the context menu for easy access when right-clicking on your downloaded ISO images, guaranteeing the authenticity and integrity of every file.
Some other features include better support for high-resolution displays, an updated look and feel, and improved in-house tools such as the Driver Manager and Software Sources. The Driver Manager is now easier to use and can run in user mode, so it won’t ask for your password when launched. Additionally, the configuration of removed drivers can now be easily purged. Software Sources has also been updated, with better handling of PPA keys. These improvements make Linux Mint 21.1 “Vera” a more polished and user-friendly release, making it an excellent choice for newcomers to the Linux world.
The following tutorial will teach you how to upgrade to Linux Mint 21.1, codenamed Vera from Linux Mint 21.0, Vanessa, using the terminal with CLI commands. The Linux Mint team does not recommend this method, but it does work well for your standard Linux Mint system, given it is only a minor upgrade and not a major release.
