Sparky of the testing ((semi-)rolling) line is based on and uses Debian “testing” packages.
Users of Debian “testing” branch should add Sparky sisters (testing) and core repositories to get access to Sparky repos:
sudo nano /etc/apt/sources.list.d/sparky.list
and paste into the file:
deb [signed-by=/usr/share/keyrings/sparky.gpg.key] https://repo.sparkylinux.org/ sisters main deb-src [signed-by=/usr/share/keyrings/sparky.gpg.key] https://repo.sparkylinux.org/ sisters main deb [signed-by=/usr/share/keyrings/sparky.gpg.key] https://repo.sparkylinux.org/ core main deb-src [signed-by=/usr/share/keyrings/sparky.gpg.key] https://repo.sparkylinux.org/ core main
Create a preference file:
sudo nano /etc/apt/preferences.d/sparky
and paste into the file:
Package: * Pin: release o=SparkyLinux Pin-Priority: 1001
Otherwise, install 'sparky-apt_YYYYMMDD~sparky8' packages to do so.
Download the Sparky's Public Key as a “deb” package from:
http://us2.repo.sparkylinux.org/pool/main/s/sparky-keyring/
Then install it:
sudo dpkg -i /path/to/sparky-keyring_VERSION_all.deb
or get the key manually ('wget' has to be installed):
wget -O - https://sourceforge.net/projects/sparkylinux/files/repo/sparky.gpg.key | sudo tee /usr/share/keyrings/sparky.gpg.key
