The software center of Linux Mint 20.1 Cinnamon Edge offers Viber as a flatpak package. Installation is a breeze and the only downside is that it takes a lot more space than the .deb version from the official Viber homepage. I'm not sure if it is a common problem, but for me, the indicator icon was missing from the cinnamon taskbar.
Janitor is an addon for Kodi that will automatically scan your library for watched movies, TV show episodes and music videos based on criteria such as age, rating or free disk space. I set it up to delete what we already saw after 2 days except if it is in a protected folder. It is a great tool to free up disk space on your device, but if you upgrade to a version of Kodi that is not supported, it will be disabled and you will have to delete stuff manually again.
Just had this happen to me. I didn't really watch what I was doing and issued the "sudo apt-get dist-upgrade" command which for some weird reason removed Kodi from my system. After reinstalling it with "sudo apt-get install kodi" all I got was a black screen instead of the Kodi user interface.
Last weekend I tried to get some work done while staying in the countryside. I hooked up my laptop to the net using my Android phone as a mobile hotspot and did my thing just like in the office. However, during the breaks when I tried to browse Reddit or do anything net related on my phone, there was seemingly no internet available.
