How can I add 'main/dist-upgrader-all' to '/etc/apt/mirror.list' so that my apt-mirror downloads the files for a release upgrade?

I maintain an apt mirror by using apt-mirror. It works fine for the packages of bionic and focal. Now, I want to add the files, that are needed to be able to perform release upgrades using this mirror. In /etc/apt/mirror.list I added main/dist-upgrader-all to all update sources that contain these folders.

Libre Writer showing only blank icons, how to get the file menu (and tools to change setting)
in flag

I recently opened Libre Write (LibreOffice), and noticed that the entire top bar is just a set of icons. I can get to a more contextual menu by right clicking the top bar, but "file", "tools", "settings" are all missing, doesn't seem to be a way to change the top bar to not be icons.

How would I go about changing this to contain a context menu?

Where are the quick launch entries of the top bar saved in Ubuntu 18.04 Mate 32-bit?
in flag

I am running Ubuntu 18.04 Mate 32-bit. Sometimes when I add a program shortcut to the quick launch section of the top bar, it will be gone after a restart. I hope to bypass that by manually editing the respective configuration file. I am rather new to Linux and do not want to simply edit some file by my own choice. So can you tell me which is the correct file to edit?

I pressed the Windows key, type Simplescan, see the icon come up and it's selected, and press enter. The mouse icon turns into the "loading" icon (a circle) but then nothing happens after that.

How to modify the gdm3 greeter's texts?

I'd like to change, for example, the "Sorry, that didn't work" to something else. Are the texts of the gdm3 greeter available and modifiable somewhere in the system?

I am aware that this might cause problems if I need to debug my system in the future, since I can't use the defaut messages anymore. However, the default messages are so easily attainable that I don't see this as a problem.
