I recently upgraded from 18.04 to 20.04 with Kubuntu. I had to delete Python2 to do it, but it worked.
However, since the update, something strange is occuring with the copy paste function. A piece of copied text can be pasted into an empty place; however, if the text is being pasted in replacement of other text, however, it instead copies the text being highlighted!
For example, say I copy
hello. If I paste it into an empty text field, I get
hello. However, if I copy
world, then highlight
hello and try to paste it there, it will instead copy the text
hello instead, meaning that every paste after that will just be
What could be causing this strange behaviour? The keyboard shortcuts look correct...
