The issue is not present in Ubuntu 20.04 or later. The question is if dropping the patch retroactively as a bionic stable release update should be done. I discussed this with Sebastien Bacher in the ubuntu- desktop team, and we concluded that we are not able to tell that no bionic user depends on the patch, so we won't drop it for bionic.
In case of libvirt-qemu you provided a nice workaround, which may be useful for other users who encounter the issue. ** Changed in: accountsservice (Ubuntu) Status: Triaged => Fix Released -- You received this bug notification because you are a member of DX Packages, which is subscribed to accountsservice in Ubuntu. Matching subscriptions: dx-packages https://bugs.launchpad.net/bugs/1903449 Title: accountsservice displays "Libvirt Qemu" Status in accountsservice package in Ubuntu: Fix Released Bug description: Installing libvirt-manager results in account libvirt-qemu being created. This user has config in /etc/passwd like follows: libvirt-qemu:x:64055:125:Libvirt Qemu,,,:/var/lib/libvirt:/usr/sbin/nologin The "nologin" should be pretty clear signal that this account is not usable for logging in. Despite this, this account is offered in visual login (e.g. lightdm). The computation for possible user accounts is handled by package accountsservice. A workaround is to manually list this user as system user: echo -e "[User]\nSystemAccount=true" > /var/lib/AccountsService/users/libvirt-qemu However, as this user cannot be logged in (/etc/shadow contains "!" as the password hash, too) it never makes any sense to show this in login screen even without the above manual configuration.
