Upgrade between Linux Mint versions

Upgrade from 19.2 to 19.3: by means of the terminal (emergency measure)

Sometimes upgrading by means of Update Manager doesn't succeed, for unclear reasons. Even in cases when the official upgrade feature has already been made available.

In that case you can do the upgrade as follows, by means of the terminal:

a. Launch a terminal window.
(You can launch a terminal window like this: *Click*)

b. In your sources list, replace the Tina source by the Tricia source. For that, use copy/paste to transfer this line into the terminal (it's one line):

sudo sed -i 's/tina/tricia/g' /etc/apt/sources.list.d/official-package-repositories.list

Press Enter. Note that your password remains entirely invisible, not even dots will show when you type it, this is normal.

c. Then you update the packages list, like this:

sudo apt-get update

d. Then you perform the actual upgrade, in this way:

sudo apt-get dist-upgrade

NOTE: I did the first command (replacing sources) in normal terminal. For extra safety I did the other commands in tty/VT outside Xorg/desktop (CTRL-ALT-F1)

—  on those safety reasons SEE ANSWERS UNDER THIS QUESTION
