Cisco ASDM “Unable to launch device manager”

Seems every time theres a Java update ASDM breaks…

A simple fix is to access via Firefox https://(your IP) and run the ASDM through the browser. Once you successfully connect you will have a new shortcut on the desktop for the ASDM, fixed!

If for some reason you don’t have the shortcut, open Control Panel->Java Control Panel and under Temporary Internet Files select View, click ASDM and on the top toolbar there a button to create a shortcut on your desktop.

Note: don’t bother with IE11 as the quantity of hoops you need to jump through to get it to work will just drive you nuts.


Upgrading Ubuntu to 14.04 “not enough free disk space” on ‘/boot’

While upgrading Ubuntu to 14.04 you receive the error “not enough free disk space” on ‘/boot’ you need at least 57m free.

Check your space:

fdisk -l &&df -h

List unused images:

dpkg -l | grep linux-image

The fix, this removes all unused kernels:

dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/(.*)-([^0-9]+)/1/")"'/d;s/^[^ ]* [^ ]* ([^ ]*).*/1/;/[0-9]/!d' | xargs sudo apt-get -y purge

Check space, reboot and rerun upgrade:

fdisk -l &&df -h
