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

[WheezyE]

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 termux/proot-distro#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

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

Thank you very much! User account creation in 32-bit (arm) Ubuntu-hirsute proot is now working
