Until we switch our dedicated server rack out for our new virtualization server, we are left with providing updated ISO’s on a monthly basis. We have found that with certain size updates of certain packages, command line intervention is required. This has been happening for ISO images older than one month. Sometimes sooner, sometimes later. The correct procedure to fix this is to…

Open “konsole” and type the following…

sudo su

apt update

apt upgrade -y

Answer all questions presented. Use default options when asked, or say yes when asked questions. Some of the questions will be along the lines of certain services require a restart to function correctly, would you like to restart now, or to specify grub boot device. After the upgrade is completed, you can reboot the system and it will work like normal. In the future, we will be providing nightly install images. Using a confirmed “working” build ISO will solve this issue as it will already be up to date.

Also, the KDE devs have dropped the ball with Plasma Discover (The official PackageKit front end for KDE). Plasma Discover will sometimes not present the update button in some test cases. Also, packagekit in debian sometimes crashes causing crashes in Discover. Apper has been included as a graphical alternative to discover and is quite easy to use. Apper is a direct KDE frontend for Debian Apt. If you require a graphical package manager and Discover does not work, use this instead. In a later version of TTOS Linux, we will provide a package that makes Apper the default package manager and update manager for KDE in the event Discover stops working for some users. We found that this happens on some updates and is fixed with some following updates however it is an ongoing issue in some test cases (not all). The KDE team is aware of the issue as bug reports have been files with numerous other distros but I have complete confidence that they will eventually figure it out.
