Unable to install package post adding ppa
Solution 1:
Update 2020-06-21
The PPA ppa:nilarimogard/webupd8 currently contains packages for Ubuntu up to 20.04 LTS.
So you can install WoeUSB as usual:
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get install woeusb
Also the WoeUSB package exists in ppa:tomtomtom/woeusb PPA:
sudo add-apt-repository ppa:tomtomtom/woeusb
sudo apt-get install woeusb
Note: to prepare this answer I have used special PPA search page on LaunchPad.net - https://launchpad.net/ubuntu/+ppas .
Solution 2:
Dependency is added in version 3.3.0-1 in my ppa.
Thx for reporting the issue.
