Flutter SDK installation fails because gpgv crashes on Ubuntu 25.10 (Questing)

[nox-rael]

Hello,

I found a reproducible issue while trying to install the Flutter SDK using the built-in installer.

Environment:

• AndroidCodeStudio Lite
• Ubuntu 25.10 (Questing Quokka)
• ARM64

Steps to reproduce:

1. Open the integrated terminal.
2. Run:

android_sdk_setup --install --flutter

The installation fails because APT cannot verify repository signatures.

After further investigation, the root cause appears to be that gpgv crashes.

Running:

gpgv --version

produces:

gpgv: FATAL: error reading '/proc/sys/crypto/fips_enabled' in libgcrypt: Function not implemented
Aborted

As a result:

• apt update fails
• repositories are reported as unsigned
• package installation fails
• Flutter SDK installation cannot continue

Additional information:

The filesystem itself appears to be functional:

pwd
/root

ls /
(works normally)

Creating directories under /home also works.

This seems to be related to the compatibility layer used by AndroidCodeStudio, where access to:

/proc/sys/crypto/fips_enabled

returns "Function not implemented", causing gpgv to abort.

Could you please investigate whether this is a compatibility issue with the current Ubuntu 25.10 image or the ACSIDE runtime?

Thank you.
