Try removing "$PREFIX/etc/apt/sources.list.d/termux-adb.list" first. It seems you already have a conflicting package source configured.

I did

rm $PREFIX/etc/apt/sources.list.d/termux-adb.list

Still same issue

[nohajc]

What else do you have in sources.list.d? You shouldn't need to delete anything else but I'm just curious.

You could also download my install script, try to run all the commands one by one and see which one doesn't work. One of the commands should fetch the public key. I suspect it's not being executed right now.

Anyway, the real question is whether you installed anything related before. I can't replicate the issue on a clean setup... But I remember somebody already reported a similar thing before.

[nohajc]

There is https://github.com/RohitVerma882/termux-miunlock which also ships termux-adb (an old version) but the package is renamed so I can't see how that could be a problem.

[nohajc]

Ok, does it fail when you just run apt-get update?

If it reports the GPG error, we need to find where the broken configuration is.

cd $PREFIX/etc/apt
grep -r "https://nohajc.github.io"

Running apt-get update outputs this:

The error only occurs after adding the ADB repo to the sources

echo -e "deb https://nohajc.github.io termux extras" > $PREFIX/etc/apt/sources.list.d/termux-adb.list

Running

wget -qP $PREFIX/etc/apt/trusted.gpg.d https://nohajc.github.io/nohajc.gpg

Then

apt update

Outputs this:

I am doing further investigation since it's working fine on my other device.

[nohajc]

Are there any other keys in $PREFIX/etc/apt/trusted.gpg.d which apt already detects?

[nohajc]

You could also try explicitly setting the path.

deb [signed-by=/data/data/com.termux/files/usr/etc/apt/trusted.gpg.d/nohajc.gpg] https://nohajc.github.io termux extras

Or whatever else the $PREFIX variable resolves to.

Deleting unnecessary keys and running

curl -o $PREFIX/etc/apt/trusted.gpg.d/nohajc.gpg https://nohajc.github.io/nohajc.gpg

seems to fix the issue, but now i'm getting

Update:

Fixed, it was just a conflicting package pkg uninstall r-termux-adb fixed the issue

[nohajc]

Yep, I was about to suggest that. This package is pulled by https://github.com/RohitVerma882/termux-miunlock I believe and it's just an older version of my tool.

Unfortunately, it causes this conflict. The package was renamed but all its contents would have to be renamed too.
