I’m a complete noob about Ubuntu and use it on my office PC. These are the details of my release: Distributor ID: Ubuntu Description: Ubuntu 16.04.3 LTS Release: 16.04 Codename: xenial
I’ve used it without encountering any problem for the past 6-9 months. I have the habit of updating the system once a week or so (sudo apt-get update, sudo apt-get upgrade and sudo apt-get dist-upgrade) and everything seemed to work perfect till about 2 weeks ago.
Over the last 2 weeks though, running those commands started returning a host of errors. MY libreoffice was corrupt too and I uninstalled it to install a clean one, but to my shock I can’t install a new version either. I followed a lot of threads here and did a dozen things, which I’m afraid exacerbated my problem. I tried changing the servers and all, and in the process my “Software and Updates” stopped working completely.
Only my Synaptic Package Manager and it too returns the following error when I tried to reload packages.
Thanks in advance guys.
This is the message I get in Synaptic Package Manager.
