sometime wrong when i use proot on andriod10 （huawei mate30 Pro with emui10.0.0.182）

[black-A]

$apt install proot -y
......
.....

$termux-chroot
proot error: execve("/usr/bin/bash"): No such file or directory
proot info: It seems that termux-exec is active and is prepending /data/data/com.termux/... to executable paths
If this is path is not available inside proot, please "unset LD_PRELOAD"
fatal error: see proot --help.
proot error: trying to remove a directory outside of '/data/data/com.termux/files/usr/tmp', please report this error.
proot error: can't chmod '/data/data/com.termux/files/usr/tmp/proot-19463-v1QCNP': No such file or directory

so ，what is going on？I am just a newbie。

[oxr463]

If this is path is not available inside proot, please "unset LD_PRELOAD"

Did you try this?

[black-A]

thanks for you help@oxr463，do you mean just Enter this command （unset LD_PRELOAD）directly？
I just tried it ，and Now it looks like this：

$ unset LD_PRELOAD
$
$
$ termux-chroot
proot error: execve("/usr/bin/bash"): Function not implemented
proot info: possible causes:

• the program is a script but its interpreter (eg. /bin/sh) was not found;
• the program is an ELF but its interpreter (eg. ld-linux.so) was not found;
• the program is a foreign binary but qemu was not specified;
• qemu does not work correctly (if specified);
• the loader was not found or doesn't work.
  fatal error: see proot --help.
  proot error: trying to remove a directory outside of '/data/data/com.termux/files/usr/tmp', please report this error.
  proot error: can't chmod '/data/data/com.termux/files/usr/tmp/proot-32151-QMa1Cw': No such file or directory
  $

if I did someting wrong？thanks again！

Is this a general problem with running proot under Android 10? Reproduced by me on a Mate 20 pro, by @Grimler91 on a samsung device and also by me on an Android 10 emulator.

Seems to be -ARGS="$ARGS -r $PREFIX/.. which is not working?

Using this diff: https://gist.github.com/fornwall/e2cb15e77f49d3ff176ab5f2fb8b4caa, termux-chroot starts to work somewhat (no /bin folder, and / cannot be listed as it's the root of the Android file system).

@michalbednarski Any idea what is going on?

Happens to me too on Galaxy s9+ Android 10, clean install.

[michalbednarski]

On Android 10 /system/bin/linker (which is neccessary to execute dynamically linked executables) has became symlink to /apex/com.android.runtime/bin/linker, it will be neccessary to add /apex to bind mounts.

@michalbednarski I can confirm adding:
ARGS="$ARGS -b /apex:/apex" to termux-chroot fixed the problem, thanks!

[azadlaw11]

@michalbednarski can u explain i dont understand

[RalfWerner]

it will be neccessary to add /apex to bind mounts

@michalbednarski -b /apex solves the problem of termux with compileSdkVersion 28 but not with 29 or android-R on a Q10/R11 device. Has anyone successfully checked this yet?
