Well, my reason for doing so is to create a linux environment in which I have installed only those applications that I would actually be using.
I appreciate your input, and I will work on my syntax. That issue notwithstanding, I am still having persistent issues unaddressed. I cannot access the bootloader menu and switch to other bootable devices.
What I have been told, and read in the other forum posts, is that the ‘esc’ key is what is pressed to access the boot menu. That simply is not true on my machine. I am looking into the comment made by user FranklyFlawless, concerning reflashing the coreboot firmware, as stated here.
What I see upon system startup is the following:
- Hard drive decryption prompt;
- Loading bar with no text;
- PureOS splash graphical overlay;
- User profile select/login;
and between steps 2-3 I can press the ‘esc’ key to access the kernel init script (black screen, green text, etc.), nothing more.
As I have already stated earlier, upon attempting to update PureOS and/or any of the preinstalled apps via the ‘Software’ application, it declared that there were unmet dependencies; furthermore, that the packages cannot be found for individual applications. As adding/removing programs is the sole purpose of the ‘Software’ application, if it is non-usable for that intended purpose, I have no use for it. I seek to optimize the system.
Switching to the terminal and inputting:
sudo apt update
sudo apt upgrade
I found that the ‘Software’ application still listed the PureOS update as pending. When trying to complete the update via the app, it would display a similar message of “unmet dependencies”, but fail to display what those dependencies were, for the message being cut off.
This was addressed by help from the technical support staff, as stated earlier, here. I am also experiencing erratic behavior of the operating system, such as the ‘Software’ program being opened while I am running ‘Tweaks’, specifically when I am in the “extensions” menu. I do not know what to attribute these all to.
Edit: my mistake on that last one (see edits).
