The software avidemux seems to be no longer available in Ubuntu 18.04.
The command
sudo apt install avidemux
gives the prompt
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package avidemux is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'avidemux' has no installation candidate
So what is the GUI alternative of avidemux?
