Hi
everyone, how's it going? After you have initially installed Peppermint, you
need to run a post-installation update and upgrade. Running these simple commands can and will in many cases resolve the little niggling issues a fresh installation can throw at you. Since the time when your installation ISO was originally created, the kernel and the supplied software packages will have gone through several upgrades.
Peppermint, like other Linux distributions is a very dynamic and rapidly evolving operating system. Consequently, it needs to be kept as current as possible for optimal performance.
Please open a terminal window with the following keystrokes:
Ctrl+Alt+t. Enter the following commands into the terminal window.
Tip: Linux is case sensitive. To reduce the possibility of typographical errors please use the
Code: [Select] function below to highlight the contents. Click on the centre mouse button/wheel while in the terminal window to paste the contents.
Note: For enhanced security, passwords are entered invisibly. There is
NO indication of any user input. You may enter an incorrect password
3 times before you have to repeat the action you are trying to execute.
apt update && apt upgrade
Hit enter and enter your user password when asked. Follow the on screen instructions. After this has completed, continue with:
Hit enter and enter your user password if asked. Follow the on screen instructions. This last process can take a long time depending on your machine's performance. You may be asked to re-enter your user password again during the
dist-upgrade process. Again, this depends on your machine's performance. Its a good time to get a cup of coffee or tea - a slice of cake maybe

.
After the upgrade has completed, reboot your machine because it is highly likely that there will be kernel upgrades. Now that this is completed, everything is up to date and your software is synced. Hopefully, any issues you were experiencing will now be resolved. I hope this helps - have fun
