# APT updates notifier
2+
3+
This applet monitors if updates are available for systems using APT tool (like
4+
Debian). It also allows viewing available updates and installing them through
5+
the popup menu.
6+
7+
In order to have updates count refreshed, some external way to do this is
8+
needed (e.g. enabled automatic updates checking in `gnome-software`, or some
9+
other way to periodically run `apt update`).
10+
11+
## Settings
12+
13+
You can:
14+
15+
- change refresh timeout
16+
- change default (`apt update/upgrade`) commands to your own.
17+
- enable showing three (configurable) levels of icon to show how many packages
18+
are waiting for the upgrades.
19+
- hide applet if there are not updates available
20+
21+
## Dependencies
22+
23+
- `gnome-terminal`
24+
25+
## Icons
26+
27+
Icons are based on [Papirus icon theme](https://github.com/PapirusDevelopmentTeam/papirus-icon-theme).
