Hello community, perhaps someone can help me? I accidentally shut down my laptop while it was updating and now it doesn't boot properly, it stops at the kubuntu flashing screen. I tried to turn off automatic updates (https://www.garron.me/en/linux/turn-...ic-update.html) and also remove the memory cache (free && sync && echo 3 > /proc/sys/vm/drop_caches && free) but nothing helped. Any ideas? Thanks in advance. K

Did you try booting into the recovery mode (selected via grub)? You could then try to restart the upgrade with
apt-get update
apt-get upgrade
You may need to run
dpkg --configure -a
to fix the partially installed packages.Using Kubuntu Linux since March 23, 2007

Two ways to make a WIFI connection via the CLI:
First;
$ sudo iwlist wlan0 scan
# this generates a list of ESSID's like "MyConnection"
$ sudo iwconfig wlan0 essid "MyConnection"
# this will connect to the access point called "MyConnection"
$ sudo dhclient wlan0
# this will set up DNS.
# In case of WPA encryption:
$ wpa_passphrase YOURSSID YOURWIFIPASSWORD
Now you should have access.
=============================
Second;
1. Turn the interface on with the following command:
sudo ifconfig wlan0 up
2. Scan for a list of all the available access points:
$ iwlist wlan0 scanning
3. Select the access point with the following command:
$ sudo iwconfig wlan0 essid ACCESSPOINT
4. Set WEP or WPA passphrase, if needed:
$ sudo iwconfig wlan0 key PASSPHRASE
5. Finally, connect to DHCP server and obtain an IP address:
$ sudo dhclient

Unfortunately, in the first case the shell never recovers after the command
$ sudo dhclient wlan0
and in the second after i hit
$ sudo iwconfig wlan0 key PASSPHRASE
i get the message
$ Error for wireless request "Set Encode" (8B2A): invalid argument "MY PASSWORD"

The command for activating WPA is "wpa_supplicant -i wlan0 -c passphrase_file". This puts it in the foreground and you can see its messages. Press CTRL-Z to go background, type "bg" and then enter "dhclient wlan0" when you are connected. I always have WPA keys, it's the most common scenario.Last edited by xennex81; Jun 29, 2015, 02:48 AM.
