LibraZiK-4 manual - Installing LibraZiK-4 - method 2
Here we will see how to upgrade a LibraZiK-3 audio studio to a LibraZiK-4 audio studio.
Launch the Synaptic software and go to synaptic menu→ Configuration → Repositories.
In the end, you should have these repositories:
Then click on the “Accept” button, then on the “Reload” button in the main Synaptic window. Synaptic will then update the repository indexes. This may take a few minutes.
Then click on the “All Upgrade” button of Synaptic, then on the “Add to Selection” button.
Finally, click on the “Apply” button.
Now click on “Apply”.
During the update, you may be asked several things.
A summary of important changes will be presented to you. You can read them if you are curious. In any case, you will have to click on the “Close” button to continue the update process.
The installation of the libc6 package will ask you whether to restart the services automatically.
If you do not know how to choose here, write “yes” to the question: Restart services during package upgrades without asking? [yes/no] and then press the [ENTER] key.
It is possible that Synaptic will warn you of the presence of duplicates in the repositories:
However, this message will reappear every time if we don't fix the problem now, so let's do it once and for all.
What happens is that some of the repositories addresses are filled in twice. That's all. As a reminder, these repositories addresses are (to make a long story short) addresses on the Internet where Synaptic will look for lists of installable software.
To do this, you can delete the following files:
/etc/apt/sources.list.d/LZK-PAP-users.list. BE CAREFUL to delete ONLY the files with PAP in their names, and not those with BAP.
To remove them, you can use one of the following commands (depending on how you installed your system, you will use “su” or “sudo” to switch to admin account) :
su -c 'rm /etc/apt/sources.list.d/LZK-PAP-users.list'
sudo rm /etc/apt/sources.list.d/LZK-PAP-users.list'
Then close Synaptic, and restart it. You will no longer get the above message.
Manually delete the
~/.config/qt5ct/qt5ct.conf file, the system will recreate a clean (and compliant!) one the next time it starts.
Reboot: LibraZiK menu → System → Shutdown… then choose “Restart”.
Once the machine is restarted, you will see that the graphic theme is not completely restored. To do this:
Note that the update will not remove the kernels that were installed on your LibraZiK-3 system. So you have to do it manually.
To finish installing your LibraZiK-4 audio studio, you will want to add some configurations to your system.
