I can see that the VPS's and SSH2 are installed and I did access so the port 22 must be open in the firewall or a public IP/ and I assigned the port to my server. I think it was already available, so I tried at the command prompt and saw if I got a usage help message, and I can see that I did it and prove that I already had it.

Few months ago, I didn't know that installing Python 3 on a Linux Server using RPM isn't too much of a hassle, Infact, I wanted to enable software collections (SCL) to get access to the newer version of Python, using sudo yum install centos-release- scl and hitting enter. I actually did see that it was enabled, then I decided to install Python 3 and keep that in mind every time , I would sudo yum to install rh- Python35. After the Python installation I've decided to enable the Python version I had installed and I did this using the command scl enable rh Python 35 bash and I've finally seen that Python 35 was installed on my Linux Server using RPM.

I actually manage to use SSH 'pair' on the user and server I have seen that I can connect securely to the Server without sending across the password that could be intercepted, I had realize that the private key belongs to the user and is encrypted, I could see that the public key was on the Server and is used to decrypt the private key when it reaches the Server during the initialization of an ssh session and that is how I manage to master it and prove this will continue to improve my skills.

Talking about the VPS's and SSH2, last time I couldn't see that access possible that the port 22 must be open in the firewall or a public IP and the port should have been assigned to my Server, but later on I've decided to ask my colleague about this.

I was concerned about using Centos Linux not (stream) because for me it is a reliable and stable system. Centos stream really surprised me because Fedora is the guinea pig for all experimental stuff and I have Centos stream for the same reason.

I was trying to handle unmet dependencies with Python 3.9 (package management, Python, Dpkg Linux), I had catch an error and disable the functionality of my program, loading the string library and couldn't find it, so I've decided to disable all functions of my program that use strings and this has helped me and I didn't struggle that much.

Last year I was using Kubuntu, there is an update that pops up when there are updates available. The results is update that are on time and effortless. When I choose to apply the available updates, I can leave the updates process running in the background and go right ahead with whatever I was doing. The only thing that I didn't know and my colleague had told me about is that the only time an update requires a reboot is when a kernel has security issues, unlike windows that reboot is at my discretion, not when the OS deems necessary.

Two years ago, I was using this approach to install software with a package manager as I've tried using a prebuilt package using script and my colleague had told me that most Linux distributions use the former.

The package names of the dependencies dpkg list and try to reinstall them. I found out the quickest and the easiest way, to do this is to use synaptic. If I locate the original deb package name and Mark for Reinstallation, the system will pull in and install the missing dependencies.

Most often it's because I forgot to elevate with sudo, I guess will be held packages, then I think we odd circular dependency problem which usually involves manually removing the offending packages, one of my friend shad told me that I must never enter commands in the Terminal unless I know what they do and he told about the web search to find out what they do, or open the terminal and type.

I was just thinking if I want to install a movie player and the programmer didn't seem to write a code for all of it's functions, but I've decided to use the libraries for them, audio, video, codecs, subtitle,formats and graphical widgets to read files from the file system. I can see that in programming this is usually the case, I had to reuse someone else's library to fit my needs and this is also called dependencies.
