Updating Linux

The time has come to update from wasta 16.04 to something newer.

The reasons I'm dissuaded are that things have been stable for almost 7 years.

  • I'm not sure what will break.
  • I'm not sure which applications I don't want anymore.
  • I have several programs that require custom install. These include:

  • xlingpaper - which is fine

  • zotero – which is working on the new version.
  • kla which is a custom headache
  • unicode tools written in perl which is a custom headache.
  • GrassGIS which I rarely use.
  • My installed version of Hugo
  • My installed version of GoLang

Why I need to move.

  • I need to use obsidian and the snap package won't work.
  • Chromium is out of date.
  • slack is out of date and not updating.
  • Browser based warnings that I am using an old browser on some websites/services.
  • JuypterStudio / tools wont run

I want to get rid of:

  • Rstudio
  • Anaconda
  • brew

I'm thinking about following these instructions:

Before I do that I need to bet a list of the various software I have installed:

OK I did update on may 29th... it took 10 hours. Now I'm sorting out all the visual theme stuff I lost in the process something about unity vs gnome. Chromium updated fine, brave installs. I had to uninstall vivaldi, and signal Tom get the upgrade to work. Obsidian and slack now work. There is the question on if i should just move up the ladder to 22.04.

Extracting images from PDFs

Every now and again I need to extract some images from a PDF. The best solution I have found is to use pdfimages on the command line in linux.


Get the tool in poppler set of tools as XPDF is out of date.
