In Ubuntu 18.04, I have added some applications/softwares as "Add to Favorites" to Dock. On reboot, it got resets, and I need to do the same again.
changes happens to manually added ones. For example, chrome, gedit etc.
I have removed Thunderbird,Amazon from dock, but, they doesn't come back.
Now I have added chrome to dock, but on reboot it shows only apps that were left to the chrome.
How can I solve this?
