[SOLVED] FTP service installation error

s0pan · 01-20-2012, 02:59 AM

I'm trying to remove the ftp service so I can reinstall it. Using apt-get remove and apt-get purge didn't remove it properly and apt-get install won't overwrite it. Here's what I get now:

"
:~# apt-get remove vsftpd

...After rebooting run a couple of more commands:

..? Please advice

Open a terminal, become root and then:

Code:

cp /etc/shadow /etc/shadow.bak
gedit /etc/shadow

Replace gedit with nano if you're on a cli (gedit doesn't work on a cli, it needs a GUI)

Find the ftp entry and remove that line, and ONLY THAT LINE, from the file. But before you do, create a copy, the code above does just that. Re-run the purge command.

For some reason there was no ftp entry in etc/shadow. It did exist in etc/passwd though.
I copied one of lines in etc/shadow ("ntp:*:14638:0:99999:7:::") and edited it to "ftp:*:14638:0:99999:7:::" then ran "apt-get purge vsftpd". It worked, vsftpd was removed and ftp entries in both "/etc/passwd" and "/etc/shadow" vanished, excellent!
Now to install anew:

:~# apt-get install vsftpd

Sorry but you didn't think it would be that easy huh?
OK checked last modified file date it's 2011-05-07 so indeed overwrite did not happen, here's the contents of "/etc/logrotate.d/vsftpd":

Code:

/var/log/vsftpd.log
{
   create 640 root adm

   # ftpd doesn't handle SIGHUP properly
   missingok
   notifempty

}

Great so I figured if I run mv "/etc/logrotate.d/vsftpd" "/etc/logrotate.d/vsftpd.bak" to rename the file it doesn't have to overwrite.
But, it made no difference! "apt-get install vsftpd" gives the same output as above, even when "/etc/logrotate.d/vsftpd" does not even exist.
Unpack seems to fail, how to proceed?

Try apt-get with the ' -f ' option.

Code:

apt-get -f install

Good to see you've made such good progress on your own!

Apt is using the package from its cache to install, and that might be obsolete or corrupt. Clear the cache so apt is forced to fetch the latest version. Btw, did you removed it with the remove or purge option? In case of the former, try the latter first, as it'll remove any associated config files with it. Your message also shows an unfulfilled dependency and a conflict with the wd-nas package. Unless you explicitly need it, I'd suggest to purge it from the system too, to avoid such conflict. But it may be a dependency of the vsftpd package, I don't know...

PS: I assume you've already refreshed the package list with apt-get update... If you haven't, do so before continuing!!

Thanks for the guidelines, finally got it installed!

dpkg -i --force-overwrite /var/cache/apt/archives/vsftpd_2.3.2-3+squeeze2_powerpc.deb
