Experiment: Mint 18 KDE upgrade to 19

[kukamuumuka]

Abstarct: This is not a tutorial, and I do not recomment to follow my experiment!

Mint 18 KDE does not upgrade to the version 19, but if manipulating the system thinking itself to be something else that KDE distro, upgrade can do. I edited /etc/linuxmint/info file as

Code: Select all

RELEASE=18.3
CODENAME=sylvia
EDITION="MATE 64-bit"
DESCRIPTION="Linux Mint 18.3 Sylvia"
DESKTOP=MATE
TOOLKIT=GTK
NEW_FEATURES_URL=http://www.linuxmint.com/rel_sylvia_kde_whatsnew.php
RELEASE_NOTES_URL=http://www.linuxmint.com/rel_sylvia_kde.php
USER_GUIDE_URL=`yelp help:linuxmint`
GRUB_TITLE=Linux Mint 18.3 MATE 64-bit

After editing, upgrade went the next way:

Code: Select all

sudo apt-get clean
apt install mate-desktop-environment-core mintmenu timeshift lightdm lightdm-settings slick-greeter
apt remove --purge mdm mint-mdm-themes*
sudo dpkg-reconfigure lightdm
sudo reboot

I ran Timeshift at once and disabled scheduled backups during an upgrade. Then I backed up /etc/apt/sources.list.d folder

Code: Select all

cp -ar /etc/apt/sources.list.d sources.list.d.bak

Then I ran

Code: Select all

apt install mintupgrade
mintupgrade check
mintupgrade download
mintupgrade upgrade

Mintupgrade ran until ended to error, when I ran it again

Code: Select all

mintupgrade upgrade

Again error, so I ran

Code: Select all

sudo dpkg --configure -a

And when configure was ready, I ran

Code: Select all

sudo reboot

X did not appear, so I login into tty and ran startx

Desktop appeared and I opened mintupdate and installed a huge amount of updates.

Happy end and Mint KDE 19 is running.
