Low graphic, PC couldn't start

[satimis]

Hi all,

Host Ubuntu 12.04 desktop 64bit
VM Ubuntu 12.04 server 64bit
Virtualizer Oracle VirtualBox

I followed;
Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 12.10)
http://www.howtoforge.com/virtual-users-and-domains-with-postfix-courier-mysql-and-squirrelmail-ubuntu-12.10

installing the LAMP server on the VM running remote installation on the host terminal vis ssh. It worked without problem. After having finished "1 Preliminary Note" I took a break with the PC switched off.

After the break I started the PC and the server on the VM. Unfortunately I forgot to run;
$ ssh user@192.168.0.101
on the host terminal to login on the server.

Then I followed "2 Install Postfix, Courier, Saslauthd, MySQL, phpMyAdmin" installing;

$ sudo apt-get install postfix postfix-mysql postfix-doc mysql-client mysql-server courier-authdaemon courier-authlib-mysql courier-pop courier-pop-ssl courier-imap courier-imap-ssl libsasl2-2 libsasl2-modules libsasl2-modules-sql sasl2-bin libpam-mysql openssl phpmyadmin apache2 libapache2-mod-php5 php5 php5-mysql libpam-smbpass

installing those packages on the host terminal and finished up to "4 Create The MySQL Database For Postfix/Courier".

Then I realised having made this mistake installing those packages on the host. I started removing the installed packages on host terminal by;

1)
$ apt-get remove postfix
(no problem)

2)
$ sudo apt-get phpmyadmin apache2 libapache2-mod-php5 php5 php5-mysql
(also no problem)

3)
IIRC on running;
$ sudo apt-get openssl

I was NOT allowed to remove it, suggesting to run "autoremove"

On running;
$ sudo apt-get autoremove openssl
Suddenly I saw it starting removing GNOME packages.

I could not stop the action even with the terminal closed.

I switched to F3 (Text Mode) and rebooted PC. But I could not started the host, warning low graphic.

I think I could start rescue mode dropping to shell. Please help how to rescue this PC. There are about 20 VMs running on this box.

TIA

B.R.

Try reinstalling the packages you removed with the autoremove command. To see what exactly got removed check /var/log/dpkg.log, If you can't get an Internet connection in recovery mode check if the packages you need are still present in /var/cache/apt/archives. Then you can install them using:

dpkg -i packagename.debAs for the VMs I think it's possible to backup them from a LiveCD.

Hi,

Thanks for your advice.

I already fixed the problem with following steps;

1) Booted to Init-1
2) Ran;
$ sudo apt-get install --reinstall ubuntu-desktop
$ sudo reboot

Ubuntu desktop is now coming back.
