How can I disabled the signature verification

[ghost]

I want to install termux in Android Virtual Machine.
But I'm having a problem.
I can't install or update any packages.
APT return a error message:

W: GPG error: https://mirrors.tuna.tsinghua.edu.cn/termux/apt/termux-main stable InRelease: At least one invalid signature was encountered.
E: The repository 'https://mirrors.tuna.tsinghua.edu.cn/termux/apt/termux-main stable InRelease' is not signed.
N: Metadata integrity can't be verified, repository is disabled now.
N: Possible causes: unstable or tampered Internet connection, wrong sources.list, outdated keyring or host is down currently.
N: Please note that all hosting problems or other serious issues we announce on our social media pages.
N: Use termux-change-repo for switching to a mirror.

It seems like the gpg key signature verification is no pass
I try to use --allow-unauthenticated to disabled signature verification,but it's not working(Maybe my operation was wrong)
The app version is v0.118 and system version is Android 10
My mobile phone is not root because I afraid of the phone will be break down when I make mistakes(such as rm -rf . /*(. and / has a space))

In your case verification fails due to silent crash of GnuPG verification utility. This is not a bug of Termux but rather issue of your runtime environment.

Noting that applications VMOS, F1VM and their equivalents are not supported by Termux. It is not possible for us to provide support for non-standard environments, especially when they are proprietary.

These apps are not virtual machines and run a highly modified version of Android OS under proot-like software container. This implies possibility of issues which can't happen under normal circumstances.

Verification failure is not only issue which happens on VMOS/F1VM.
