I bought an Acer Nitro 5, and I'm stuck in the EFI Shell version 2.70 screen.As a not-tech guy, I have no idea what to do from here.I've been Googling to find an answer, but it just doesn't seem to be working.So far, I have set a supervisor password, and that's it.I've tried typing exit and then enter, but that leads me to a Boot Manager screen, with UEFI_SHELL as the only Boot option menu.Thank you so much for reading, and I hope to hear from you tech people soon.
I want to install and use a particular extension which only supports up to shell version 3.36. I have it installed on the Zorin's default 3.38 and have most of the functionality, so it works.... just the one function I really wanted isn't available. I don't know for sure if installing 3.36 will bring me the function I want, but I was hoping to try.
I am looking for someone to tell me it should or should not be done and the reason why. For instance, "it shouldn't be done because it would break Zorin's [insert package-name or other system function here]."
Integrated screenshot tool: A new built-in screenshot tool was added to GNOME Shell 3.38, allowing users to capture screenshots of their desktop and specific windows without having to install additional software.
That extension is for casting the GNOME DE to a chromecast device for larger screen viewing/secondary screen joining. Just like if you were to hook up an HDMI connection to your HDMI capable television.
I have trouble focusing on the smaller screen of my laptop and also prefer large screens which can display much more information side-by side. I do a lot of writing and researching for content to implement in my stories/writing project.
I would be interested to know if there's some built-in function (which works) that I'm missing. Or, if there is another extension or application package install process I can try as an alternative. Thank you for taking an interest!
I attempted to set it up a while back using Network Displays (available as flatpak, installed by default in ZorinOS Pro) but I couldn't get it to work. Unfortunately I still didn't have the time to try the suggestion by Aravisian as it's not in my home, but maybe some of them may help you.
More people have had luck with that than I, it seems. I can't even get the Network Displays to load correctly as it freezes & kills my network connection. I've already posted a reply to an old thread detailing the same issues that were happening with another user in one of the other posts here on this forum.
My apologies for very late reply. The problem is solved by my senior. He said he removed the incorrect apt file in /etc/apt. Now the mongo shell version and mongodb version is 3.6. As you said, I should consider using mongo 4.4 now. Thanks for your help and I really appreciated it !
If you are only concerned with running the mongo shell, you should install the correct version to match your server release (i.e. a 3.6.x mongo shell for use with a MongoDB 3.6.x server release) or use an administration tool which is not as closely tied to the server release version:
There are some other server upgrade approaches as discussed on Replace mongodb binaries all at once? - #3 by Stennie_X, but typically admins want to upgrade without downtime so follow the documented upgrade path recommended by @chris.
But how would I go about and really pin the specific Ruby version I want, e.g. 2.7.4 or even an older 2.6.10? I found Hydra - nixos:release-21.11:nixpkgs.ruby_2_7.x86_64-linux - which seems to be job that builds the packages, but how would that translate to my shell.nix?
By just specifying ruby_2_7 it could mean 2.7.3, which is already a year old or 2.7.6 which was released last week. So if I forget to run a nix-channel --update before entering nix-shell I could end up with a different patch version than a fellow team member. To reproduce failures, especially with third-party libraries I would say the patch version differences are meaningful.
There are a couple of alternatives. With ruby_2_7_4 = import (fetchTarball ..., while the ruby version is now fixed, different people on the project might still have different versions of, say, zlib. You could even get into situations where ruby was built with a different version of zlib than your project - which might lead to problems in some cases.
One solution is to avoid import entirely and take everything from that import (fetchTarball .... That locks things down further, and requires you to update the nixpkgs commit hash in the shell.nix each time you want to update the environment. This could be an advantage, but is also rather rigid (and leads to merge conflicts if you do it a lot - which also might or might not be an advantage depending on your viewpoint ).
Following the instructions to install a new image I was able to access and back up my files (I created a full backup image of the USB as well) then wrote a fresh 3.13 image (same version that it had been running previously) to the USB drive using GNOME Disks on a Ubuntu Laptop.
Well, It appears I have resolved this issue. I stuck the original USB stick back into the control box and for whatever reason it just worked. Maybe the contacts in the USB port just needed some exercise.
Whether you're downloading from a repository (e.g. GitHub, GitLab) or installing from the GNOME Extensions Website, extensions are distributed as Zip files with only two required files: metadata.json and extension.js.
Note that GNOME Shell has a configuration setting, disable-extension-version-validation, which controls whether unsupported extensions can be loaded. Before GNOME 40 this was true by default (users could install extensions regardless of the shell-version), but because of the major changes it is now false by default.
This field is an array of strings describing the GNOME Shell session modes that the extension supports. Almost all extensions will only use the user session mode, which is the default if this field is not present.
This field SHOULD NOT be set by extension developers. The GNOME Extensions website will override this field and GNOME Shell may automatically upgrade an extension with a lower version than the GNOME Extensions website.
The value MUST be a string that only contains letters, numbers, space and period with a length between 1 and 16 characters. It MUST contain at least one letter or number.
extension.js is a required file of every extension. It must export a subclass of the base Extension and implement the enable() and disable() methods. If your subclass overrides the constructor() method, it must also call super() and pass the metadata argument to the parent class.
Here you will have access to live code running in GNOME Shell, but fatal errors or mistakes will affect the stability of the desktop. It also means you will be using the Clutter and St toolkits.
Here you will not have access to code running in GNOME Shell, but fatal errors or mistakes will be contained within that process. In this process you will be using the GTK4 and Adwaita toolkits.
The Secure Shell Version 2 Support feature allows you to configure Secure Shell (SSH) Version 2 (SSH Version 1 support was implemented in an earlier Cisco IOS software release). SSH runs on top of a reliable transport layer and provides strong authentication and encryption capabilities. The only reliable transport that is defined for SSH is TCP. SSH provides a means to securely access and securely execute commands on another computer over a network. The Secure Copy Protocol (SCP) feature that is provided with SSH allows for the secure transfer of files.

The configuration for the SSH Version 2 server is similar to the configuration for SSH Version 1. The ip ssh version command was introduced so that you may define which version of SSH to configure. If you do not configure this command, SSH by default runs in compatibility mode; that is, both SSH Version 1 and SSH Version 2 connections are honored.
The ip ssh rsa keypair-name command was also introduced in Cisco IOS Release 12.3(4)T so that you can enable an SSH connection using the RSA keys that you have configured. Previously, SSH was linked to the first RSA keys that were generated (that is, SSH was enabled when the first RSA key pair was generated). The behavior still exists, but by using the ip ssh rsa keypair-name command, you can overcome that behavior. If you configure the ip ssh rsa keypair-name command with a key pair name, SSH is enabled if the key pair exists, or SSH will be enabled if the key pair is generated later. If you use this command to enable SSH, you are not forced to configure a hostname and a domain name, which was required in SSH Version 1 of the Cisco IOS software.
The Cisco IOS SSH implementation has traditionally used 768-bit modulus, but with an increasing need for higher key sizes to accommodate DH Group 14 (2048 bits) and Group 16 (4096 bits) cryptographic applications a message exchange between the client and the server to establish the favored DH group becomes necessary. The ip ssh dh min sizecommand was introduced in Cisco IOS Release 12.4(20)T so that you can configure the modulus size on the SSH server. In addition to this the sshcommand was extended to add VRF awareness to the SSH client-side functionality through which the VRF instance name in the client is provided with the IP address to look up the correct routing table and establish a connection.
