Jonte YH's questions

I have done sudo do-release-upgrade from 21.10 to 22.04 Ubuntu and suddenly i get this errror when i startup my computer below:

[    0.004902] __common_interrupt:1.55 No irq handler for vector
/dev/sda2: clean, 3697434/45760512 files, 55603510/183012096 blocks

What does it mean is this a serious error or can i leave it is there someone that knows something about this error?

It came up after i upgrade Ubuntu 21.10 to 22.04? I' am curious is this serious and has to be fixed or should i leave it? My computer starts normally it is just this confusing error?

Or must it be fixed i'am confused?

I want to upgrade but i get this below:

It should be released today 21 April i don't get it?

I have upgraded from Ubuntu 20.10 to 21.04 and i have to write my password two times. And the login now appears two times and i have to write my password 2 times.

And i have used the program Passwords and Keys and wrote in my old password and let the new passwords become blank and it only disable the key-ring?.

I didn't solve my problem i still have 2 keyrings and i don't understand why? I have tried to remove Key-Server but it dosen't either work? How can i solve this with only one key-ring and to enter the password only once?

One of the KeyRings is Google Chrome Key ring is it possible to merge it so i can only login once?

What is the difference between Gnome-Keyring and Chrome-Keyring?

I have upgraded from Ubuntu 20.10 to 21.04 and now when I run:

sudo apt update
sudo apt-get upgrade

I get this error below related to PostFix.

How can I solve this problem?

Is there a way to automate updates and upgrades with apt or some other package manager: Instead of writing these commands below: sudo apt update sudo apt upgrade sudo apt-dist upgrade.

I mean like the system updates or upgrades automatically ever there are some have changed?

I got this before that if flushed the apt-cache:

I have solved but i wonder does someone knows what these errors means? I don't need any solution just to interpret these error-messages?

I'm using Ubuntu 20.10 and I'm trying to get the latest signature-key and when I do that I get these lines:

root@kubernetes-worker:/home/jonteyh# curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -

Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
OK

I get a warning message here that apt-key is deprecated. How do I solve this?

Is there some way I should remove the file trusted.gpg.d or edit it?

I have tried with sudo apt-get update and sudo apt-get upgrade. And i get this error with kubernetes error: I have tried with these following commands below:

sudo rm /var/lib/apt/lists/* -vf

sudo apt-get clean

sudo apt-get update

sudo apt-get upgrade

But it hasn't worked! How can i fix this? Is it that i must get the key somehow?

How can i solve these errors or is it something with my hardware?

When i run sudo apt update i got problem with VSCode:

W: Skipping acquire of configured file 'main/source/Sources' as repository 'https://packages.microsoft.com/repos/vscode stable InRelease' does not seem to provide it (sources.list entry misspelt?)

Why does VSCode have problems?

I ran sudo apt update and and so on in the terminal, and then I got this error. I can't copy and paste this error code, so I wonder what could be the problem. Is it some permissions issue or something else?

An error occurred, please run Package Manager from the right-click menu   
or apt-get in a terminal to see what is wrong  

Error message:

This usually means that your installed packages have unmet dependencies.

My question is this error dangerous or is my computer too old and what does this error means i just wondering what i cannot do or what this means?

I have an Acer Chromebook with model-number CB3-132-C971 and it will be reach end of support in June 2022. I don't want to throw this computer away. Is it possible to install Ubuntu on this computer with an ISO-file?

How do I remove Chrome-OS totally and install Ubuntu instead? what are the steps?

I get this problem when i am trying to upgrade my Ubuntu 19.10 to 20.04.

What do these terms mean?

• End of Standard Support
• End of Life

Does this mean that I can't use this specific Ubuntu version, or something else?

Does someone knows if it exists some ppa packages source for the newest Ubuntu version 19.10 i had problem with that when i upgraded from Ubuntu 19.04 to 19.10 i didn't work?
