Hi All,

During the installation of apache I get this error: "Failed to resolve user 'brltty': No such process"

# pacman -S apache

Re: [SOLV]apache install: Failed to resolve user 'brltty': No such process

Please post the pacman.log for the installation of the brltty package,  also the output of:

Re: [SOLV]apache install: Failed to resolve user 'brltty': No such process

I've added the user and group manually, now the error is gone:

# groupadd brltty -g 964
# useradd brltty -g 964 -u 964

Thanks loqs, it indeed looks like there's something wrong with systemd-sysusers

Please post the output of:

This does not contain any passwords,  those are in /etc/shadow and /etc/gshadow.

Re: [SOLV]apache install: Failed to resolve user 'brltty': No such process

In /etc/group an entry is separated into four parts by three colons.  The user lists is delimited using commas.  Change

tty:x:5:cedric:lestirk
uucp:x:987:cedric:lestirk
wireshark:x:150:cedric:lestirk

To

tty:x:5:cedric,lestirk
uucp:x:987:cedric,lestirk
