Cannot create a new user account in Ubuntu hirsute (using DISTRO_ARCH="arm" or linux32 proot-distro) #191

Closed WheezyE closed 3 years ago

Problem description

Whenever I try to create a new user account in Ubuntu hirsute in 32-bit mode (arm) I get

Adding new group `user' (1000) ...
groupadd: /etc/group.15184: lock file already used
groupadd: cannot lock /etc/group; try again later.
adduser: `/sbin/groupadd -g 1000 user' returned error code 10. Exiting

I also can't use sudo (tty errors).

This behavior didn't exist in Ubuntu-20.04, where I could create user accounts under 32-bit mode.

I asked about this in https://github.com/termux/proot-distro/issues/159, but xeffyr suggested I ask @michalbednarski about it here. They suggested "the latest Ubuntu version use newer syscalls in glibc or somewhere else and proot really need a fix. There are chances that other distributions soon will be affected as well."

Steps to reproduce

In a fresh Termux install, I installed proot-distro, ran cp $PREFIX/etc/proot-distro/ubuntu.sh $PREFIX/etc/proot-distro/ubuntu-32bit.sh and then edited ubuntu-32bit.sh so that DISTRO_ARCH="arm" was at the top, then ran proot-distro install ubuntu-32bit which successfully installed the 32bit armhf packages. When I log into proot though with proot-distro login --isolated ubuntu-32bit and run try to create a user account, I get the errors.

I have also tried 

pkg install proot-distro git -y
linux32 proot-distro install ubuntu
proot-distro login --isolated ubuntu
# In proot:
adduser user

(though xeffyr suggested that linux32 proot-distro install ubuntu is not a recommended method for installing proot-distro's)

Expected behavior

User account creations used to work in Ubuntu-20.04

Additional information

Termux fresh install from F-Droid, installed today. My goal is to run box86 (not qemu) on armhf Termux Ubuntu proot.

Ok, I've just fixed it, update should be available in Termux apt repo as proot 5.1.107-44
