After last update of Ubuntu 18.04 LTS to newest kernel 4.15.0-55-generic 23.7.2019 I started to receive daily automatic notifications after each booting that I should install ttf-mscorefonts-installer.
But when I made command 'sudo apt-get install ttf-mscorefonts-installer' in the Terminal, I get reply that it is already installed in newest version (3.6ubuntu2).
In which program or service this ttf-mscorefonts-installer is needed ? What can I do to stop / prevent these automatic announcements ?
Purge it and install it again.
That will make it ask for the EULA again. Could it be you neglected to accept the EULA the 1st time? Because that is possible and would stop fetching the actual fonts (the package does not contain the fonts but makes a webrequest to fetch them).
