Problems with apt with Ubuntu 16.04

[ghost]

Hey. can someone help me. i setup an Ubuntu 16.04 chroot environment and it seems there's a problem with apt but new versions works fine and idk why:

I tested both Xenial and Trusty and gives me about apt can't open security status channel

Tested on my Android 9 Device

Haven't tested myself but it seems that you should be able to workaround this by LD_PRELOAD'ing library with following code

int is_selinux_enabled(void) { return 0; }

gcc sefake.c -o sefake.so -shared
LD_PRELOAD=/root/sefake.so apt update

@michalbednarski it seems there's an compilation error

sefake.c:1:66: error: stray ‘\240’ in program

Am i missing something?

Looks like some (nonprintable?) characters were added on copy-paste, try retyping sefake.c into new file

@michalbednarski It does work but it seems there's an error:

(Xenial):

dpkg (subprocess): cannot set security execution context for maintainer script: Permission denied

But Ubuntu Trusty works without errors. but it gives me symlink size changed then closed with errors when upgrading packages

(Trusty):

But This error occurs on new versions like Debian 10 when upgrading packages and didn't crash at all

Try add -L flag when starting proot

-L Correct the size returned from lstat for symbolic links.

Does that work with arm64?

I used pelya's libandroid-shmem-disableselinux.so from debian Noroot and it installs fine with -L option

[ghost]

Reopening it, seems i got failure about symlinks, even with -L when proot'ing into xenial rootfs

Although i haven't run Ubuntu 16.04 insid e proot for a while now, although I don't exactly remember how it got worked again

However in 32-bit, Ubuntu 16.04 apt upgrade works fine with -L flag but not in arm64
