Hi All, 
Thanks for the feedback, but I'm not getting there yet. 

I tried vipw, but this doesn't work. It was not on my system, installed it with opkg install shadow-vipw. But then running vipw gives me: 

vipw: /opt/etc/passwd: No such file or directory 
vipw: /opt/etc/passwd is unchanged 

Neither does adding a shell to the user (/sbin/nologin) change anything. 

Thanks for any additional idea's!

Dear list, 
I have an issue installing backuppc on my new network disk running Linux 4.2.8 ARMv71. I think I have managed all preconditions in perl (v5.28.1) and are ready to install, but I run into an issue with configure.pl [1]. It doesn't let me set the user to run BackupPC with. See the snapshot of the script output below: 

--> BackupPC should run as user [backuppc] 

getpwnam() says that user backuppc doesn't exist.  Please 
check the name and verify that this user is in the passwd file. 

But the user does exist on my system, see: 

[/.../BackupPC-4.3.1] # grep backuppc /etc/passwd 
backuppc:x:1000:1000::/share/homes/Backupuser/: 

I cannot seem to workaround this problem. Does anyone have any leads? 

Thanks a lot! 


For what it's worth, I've seen this behavior when shadow hasn't properly been 
updated, and it took (takes?) running vipw, then rebooting.  YMMV


hi, 

Might need an entry where the shell for the user normally goes. 

This is what my entry looks like: 

backuppc:x:988:983::/var/lib/BackupPC:/sbin/nologin

What vipw does is set the appropriate locks and prevent corruption while
editing the password file -- under the covers, it's often vi or vim,
anyway.  Depending on the platform, this will help trigger the shadow
update (thus my suggestion to use vipw and reboot.)  In your case, it
seems the package for vipw doesn't fit with the actual location of
passwd and shadow on your system. 


Usually it's best not to directly interact with either file, as a syntax
error can result in accounts not working, instead it is better to use
tools like adduser and passwd.  Officially, authconfig (on Linux) is
probably the right way to update whatever files must be coordinated. 
You could also just use "passwd backuppc" as root.

Hi All,
Thanks for the feedback, but I'm not getting there yet.

I tried vipw, but this doesn't work. It was not on my system, installed it
with opkg install shadow-vipw. But then running vipw gives me:
vipw: /opt/etc/passwd: No such file or directory
vipw: /opt/etc/passwd is unchanged

Neither does adding a shell to the user (/sbin/nologin) change anything.

Thanks for any additional idea's!
