debian – Ansible package module keeps installing packages

We hava a mixture of CentOS, RedHat, Debian and Ubuntu servers all over the place. I am trying to install generic packages that have the same name for all Distros. The package module seems to work only on CentOS / Redhat boxes, but on Debian boxes it keeps on installing the package. After the script completes the packages are not installed. Rerun the script and same thing. I am running Ansible on the latest Mac OS and the version is 2.9.11

What am I missing to get this to work on Debian systems?

I know that as a workaround I can use when: ansible_distribution and determine what version I am running, but that means I have to make the script longer and type the packages twice.

Ubuntu 18.04 won’t boot after installing steam

Yesterday I installed steam to play some game. The installation went well. Now as I opened the application it opened the terminal and required me to enter a password so more libraries could be installed. The only thing I remember about these libraries is that one of them had the name lib-mesa-* . I turned off my laptop fine and slept. Today in the morning my Ubuntu can’t boot. It’s either stuck on the screen where services are being started or it gets stuck on the dev sda clean 12498/49480004737 screen. What can I do to fix my Ubuntu?

redhat – Problem installing Oracle 19c to symlinked directory from RPM

I’ve created destination directory and linked it to default install path:

$mkdir /u01/oracle
$ln -s /u01/oracle /opt

Then I’ve changed the owner:

$sudo chown -R oracle:oinstall /opt/oracle

But when I tried to install RPM I got an error:

$sudo rpm -i ./oracle-database-ee-19c-1.0-1.x86_64.rpm
warning: ./oracle-database-ee-19c-1.0-1.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY

(SEVERE) The install cannot proceed because ORACLE_BASE directory (/opt/oracle)
is not owned by "oracle" user. You must change the ownership of ORACLE_BASE
directory to "oracle" user and retry the installation.

error: %prein(oracle-database-ee-19c-1.0-1.x86_64) scriptlet failed, exit status 1
error: oracle-database-ee-19c-1.0-1.x86_64: install failed

How to properly fix this problem?

boot – No grubloader menu after installing Ubuntu Budgie with windows 10 Pre-Installed (Different Drives)

(advance sorry about my English. I’m not a native English speaker)
This is the First time I’m doing the Dual Boot thing, and I am new to Linux as well. I followed some YouTube procedure. Everything went well. But the grub loader is missing. When I turn on the System it directly boots into Windows 10.

During startup, if I press F11, then windows 10 and Ubuntu shows up there in the boot options menu, and i can log into Ubuntu no problem. and the grub menu also shows up before it boots into Ubuntu OS and both Ubuntu and windows 10 is present in that menu.
But it doesn’t appear automatically without pressing F11 during Boot up process.

I tried to reinstall/repair the grub menu by inside Ubuntu by using boot-repair commands(Recommended repair option). It didn’t work for me.

I am using an MSI B450 motherboard and I tried to change the boot order by moving the hard drive in which I installed Ubuntu, but there only hard disk on which I installed windows 10 shows up and the other hard drive doesn’t appear at all.

when I logged-in to windows 10 I opened advanced system settings and checked default OS, there only windows 10 option is there. Ubuntu is not there either

Please help me with this problem.

software installation – Installing Ubuntu server create problem in my Dell R540

My problem is that when i started install ubuntu server in my server machine(Dell R540), it starts showing me the problem that “there was a problem completing the installation” and it restart with same language prompt again. so I detect the problem and it is not with my hardware machine but it is because of the ISO fie I downloaded from the ubuntu official website.
I firstly downloaded the iso from here :
enter image description here

so this iso file is responding with “there was a problem completing the installation”
after that I downloaded another ISO from here :

It smoothly worked so the question is why these two are behaving differently.

apt – Can installing .deb package which is not part of official repository , result in package dependencies problem?

As far as my understanding,

  1. If we install package from only official repository (sudo apt, installing from software center, sudo apt install ./official-deb ), all the package dependencies will be properly handled by apt and no dependencies problem will occur.
  2. Installing using PPAs, and building from the source, might lead to dependency problem.

How about if I install a .deb package which is not part of official repository (like Chrome .deb package), by doing sudo apt install ./chrome.deb Can it lead to dependency problem? If yes, is it possible to configure it so that dependencies will be handled by apt?

P.S. Sorry if it is basic question.
