"Function not implemented" Android Pie

Followed instructions here https://wiki.termux.com/wiki/Debian And got the below error

Same here. Just after an upgrade (Android 8.1 to 9) chrooted Debian started having similar issues. Example:

$ enter_deb_sid
root@localhost:~# apt update
E: setegid 65534 failed - setegid (38: Function not implemented)
E: setegid 0 failed - setegid (38: Function not implemented)
Reading package lists... Done
E: setegid 65534 failed - setegid (38: Function not implemented)
E: setegid 0 failed - setegid (38: Function not implemented)
E: Method gave invalid 400 URI Failure message: Failed to set new group ids - setresgid (38: Function not implemented)
E: Method https has died unexpectedly!
E: Sub-process https returned an error code (112)

EDIT: Running debootsrap anew rendered similar problems when installing packages Just in case, some info about my system (That's Samsung Galaxy Note 9 with Knox and some UI modifications by Samsung):

I think it's the kernel update that broke it not sure what exactly it broke though.

Partial fix commited in 60f9151b19ef498e2c7b609d13a6d55bb7d715a6, but might not be ready yet.

If that's of any help, prooted Ubuntu on UserLAnd works smoothly without any errors of this kind, but I guess the commit does a thing according to this knowledge, too :)

[gmkbenjamin]

Tested the new commit and looks like it's working again yay. Thank you.

Strange.... getting IO error when trying to import pgp key. Will do more testing

Not sure if it's proot related. See log below.

dump.txt

Same errors when running tigervnc. Strangely, running Xvnc as root works fine, however running Xvnc as an unprivileged user returns errors, also in dump.txt, however it worked fine on Oreo.
