Tips & Tricks

Although we’re in the business of helping organisations make the most of technology, we recognise that you may sometimes encounter issues which you’d like to deal with yourself, if only you could find useful documentation to guide you.

Documentation on almost everything exists on the internet, the problem is finding what you want; searching can be effective but what we hope to provide here is easy access to guidance to achieve useful tasks.

We are keen to expand this by adding information that is useful to our clients. Sometimes we write a howto, other times we provide links to good sources.

If you don’t find help on a particular issue that concerns you, by all means drop us an email and we’ll try to point you in the right direction.

Show/hold/unhold packages

Sometimes, for various reasons not covered in this post, you may need to stop a package/program from upgrading to a later version. Here’s how to do it. In these examples I’ll use teamviewer as the package. Obviously you need to change the package name to suit you!

To hold a package:

sudo apt-mark hold teamviewer

To show held packages:

sudo apt-mark showhold

To unhold a package (allow it to install to latest version):

sudo apt-mark unhold teamviewer
