I am experiencing hardware or software problems that I cannot explain, or find a solution for. As part of the troubleshooting process, I have now arrived at running an older version of the OS from a USB stick, and attempting to run the failing applications in this environment. However, I am not sure how to actually run the applications that are stored on the disk.
I always run these from the GUI launcher, so I located the ".desktop" file for one of them, opened it in _Text Editor_, and found a line starting with "Exec=". I then copied this command, and pasted it into the Terminal. For instance, with Steam:
```
>> /usr/games/steam steam://open/games
bash: /usr/games/steam: No such file or directory
```
That fails because the path goes to the USB, not the disk, so I located the mounting folder for the disk, and prefixed the path with that:
```
>> /media/pop-os/<\some-uuid\>/usr/games/steam
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0curl: (6) Could not resolve host: repo.steampowered.com
```
Aha, that fails. Not sure why, so I try another application:
```
>> /media/pop-os/<\some-uuid\>/usr/bin/winetricks --gui
winetricks GUI enabled, using Zenity 3.42.1

```
So, how do I actually run programs stored on the disk, when the OS is on the USB stick?
