Hi, I am trying to free up space on my laptop, which is running Linux Ubuntu 16.04, so have been uninstalling software packages, which is something I am quite new to. Because the xSane scanner program has been inoperative, and furthermore because my printer's packed in altogether, I decided to remove xSane and found advice here I used the command sudo apt remove xsane(I am vague about why it is sometimes called Sane and sometimes xSane, but my system seemed only to recognise the latter) and I deleted xSane successfully. Do I need to delete dependent packages? I thought this meant software that is useless without xSane, but when I issued the command sudo apt-get remove --auto-remove xsaneI got a warning message telling me that gimp was among the dependent packages it would remove and I decided not to go ahead with it, because gimp is a program I use a lot, often just because on my laptop, ImageViewer usually fails to show images (which would be another thread in itself). The article I was following also mentioned using sudo apt-get purgeand sudo apt-get purge --auto-remove to remove data and configuration files. Is this something that would help me free up memory too? Apologies for long-windedness and also for asking questions that have probably been asked umpteen other times on other threads.
