Clean up Your Boot Partition Ubuntu

If you constantly run out of space in the boot partition, you might need to run the following command to cleanup the boot partition.

First, list all installed kernels

dpkg -l linux-image-* | grep ii

Second, delete the chosen old kernel 

apt-get purge linux-image-4.4.0-XXXX*

Other command worth noting:

apt-get autoremove

or 

apt-get --purge autoremove

Cleanup this file below by removing old kernel entries.
/etc/apt/apt.conf.d/01autoremove-kernels

or

Remove the old kernels files manually
You can also remove the old kernels manually. I suggest leaving the older one and the latest.
Delete the kernels in between.

Pulse Secure Setup Wizard ended prematurely

If Juniper pulse secure will not install on your computer in my case windows 10, chances are you are running into a driver issue.
Here is how to solve it:

First Step

Open CMD as an administrator and run the following:

pnputil -e > pnplist.txt
this command enumerates the driver packages that are currently in the driver store

Second Step

then open the txt file and locate anything that says Juniter in the “Publisher name” and run the following command:


pnputil -d "Publisher name" 

in my case

pnputil -d oem8.inf

Third Step

Reinstall Juniper pulse secure
