ohhhmmm what image you used for installation? Forky is the next Debian version that will not be released before 2027. I wonder how you end up with a Forky system but still using Trxie repository configuration.
If you have a backup or not a complicated setup to recreate, I would restore the backup or start fresh over. Debian unstable/Sid is a developer playground, not meant for production. If you want to stay on edge, knowing the consequences well, Debian testing/Forky is the farthest I would go for a usable system (but you are on unstable/Sid). It is sadly moreless impossible to downgrade a Debian release, since this would mean to downgrade each and every package, which they are not really meant for in general.
Check back where you got that suggestion from to add https://deb.debian.org/debian sid or https://deb.debian.org/debian unstable to your repository lists and ban that guide/instructions . And remove the file in /etc/apt/sources.list.d which contains it.
But let’s check the keys to see what’s wrong beside that:
I am new to dietpi and was just testing.
I want to install tunerstudio dach and have a 5” LCD display connected.
Don’t remember why I did that.
But since it is just a test set-up and me not having anything important running I will just start over and see where I go from there and then come back and report.
I locked myself out. I was changing all my wireless passwords yesterday because I was giving them to people instead of creating a guest network on my openwrt routers.
The process of switching my pi via command line to the new SSID and password didn’t go as exptected.
I have a LCD connected and could change config via USB keyboard if I can find an USB adapter somewhere.
Or I could take the SD card out and configure it in the computer?
But I probably just start from scratch and not waste more time with this corrupted configuration?
Could be interesting to see (for me) what the problem with the APT keys is, but otherwise there is probably not much reason to invest time.
This one?
So installing Java, then
java -jar /path/to/TSDash/TSDash.jar
If there are any issues with the Java version being too old or too new, the Adoptium repository we add when installing Java JRE via dietpi-software offers plenty of Java versions which can be installed concurrently: JFrog
b. Ensure that “TunerStudio.sh” shows up in the results. If it is not, re-install
Note: you MAY need to install JAVA... if so, type
`sudo apt-get install openjdk-8-jre`
To set default Java runtime
`sudo update-alternatives --config java`
I think to have read that TS is a bit picky regarding the java version.
root@DietPi:~# sudo apt-get install openjdk-8-jre

Package openjdk-8-jre is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'openjdk-8-jre' has no installation candidate
I installed java via dietpi-software but I am not sure how to add Adoptium repository
This is also outdated information . apt-key is deprecated since 4 years or so and has been removed with Debian Trixie. And AdoptOpenJDK does not exist anymore, now it is Adoptium, which the Java version you already have is from. There is nothing else needed, just download, extract and start TSDash.
Java 21 is the current LTS, should be best supported in general. Only if TSDash unexpectedly requires an older or newer one (which it would print to console on startup), there would be a reason to install other version.
mm reving this, Ive recently been having issues with apt updates since last bookworm update before Christmas. I know see its showing version as Forky not Bookworm. No idea how this happened as I dont mess with repo’s. I take it no way to go back other than a re-install?
. And remove the file in
