Reset Ubuntu
Melva Simons
With install mode, all existing user and system data on the device will be removed and the device will be initialised from the system version image dated and listed in the reinstall text.
Unlike with a factory reset (see below), install mode will erase the contents of the ubuntu-save partition, reverting the device to its manufactured state, potentially removing configuration data essential to its functionality.
Most importantly, however, the running system data is untouched. This allows you to log in to the system using prior credentials to recover your data, either via SSH or locally after setting up a password for the user.
In particular, the contents of the ubuntu-save partition remains intact. This partition typically contains configuration data essential for the original functionality of the device, such as network configuration details. To fully initialise such a device, and remove all data, use install mode.
Running this command will reset, among other things: the apps pinned to the Unity launcher or Ubuntu Dock ; panel applets and/or indicators; monitor resolution and interface scaling; keyboard shortcuts; fonts, GTK and icon theme; window button placement, launcher behaviour; and so on.
Could anyone kindly provide the commands to completely reset the iptables (firewall) for Ubuntu 12.04 to its default "factory" setting? From what I understand, doing this wrong would cause one to be locked out of the linux box?
I am having a problem of creating database in Google Cloud SDK using provided scripts in a course and would like to reset the VM (Ubuntu 20.04 LTS). However, on the Google Cloud SDK documentation, I only found how to uninstall SDK from computer, which I believe is different from resetting the VM (which is on the cloud). Are these the same thing? If not, how can I reset the VM? I also have direct SSH connection with VM, can I reset using SSH?
I had lost the login details for our Ubuntu Linux Passbolt server. I booted in recovery mode to reset the password and then rebooted the server once complete. Now, upon login to the server, I can see that there is no Passbolt directory at either /var/www/passbolt or /usr/php/passbolt. I am not sure what has happened here and am hoping to please get some assistance.
We had been using self-hosted Passbolt without a hitch for 12 months or so. I exported my passwords from Passbolt before doing any of this, so if it comes to it, I can just rebuild the entire server. Although, this should only be a last resort as some of our other users would lose their data.
Checklist
[x] I have read intro post: About the Installation Issues category
[x] I have read the tutorials, help and searched for similar issues
[x] I provide relevant information about my server (component names and versions, etc.)
[x] I provide a copy of my logs and healthcheck

[x] I describe the steps on how to reproduce the issue
I have now found some files under /etc/passbolt. Although, I still cannot run a health check. Currently, our site at passbolt.domain.com.au is getting an error and the vm host IP address points to the default NGINX site.
While Ubuntu does not have built-in functionality to factory reset, it does have the ability for you to reset its settings. If you want to restore your device to its original state, you must perform a factory reset instead.
People who have used Ubuntu for a long time will sometimes need to reset the settings to the default for various reasons. Ubuntu-based distributions offer this functionality. Once a program has stopped working, leaving a terminal in an abnormal state, can be very useful. In the event that carriage return does not work, you may need to type reset to get the terminal working. This handy little trick will make the setup process more straightforward.
Ubuntu default settings are ideal for a variety of use cases. For example, they suit developers requiring a stable and reliable operating system. The default settings come with various development tools, such as compilers, debuggers, and editors, that make it easy to create and debug software.
Ubuntu default settings are also suitable for students who require a reliable and secure environment for studying. Productivity tools like word processors, spreadsheets, and presentation software help complete tasks efficiently. They are essential tools that can significantly enhance productivity and simplify tasks.
Ubuntu default settings are an excellent choice for users who want a stable, reliable, and user-friendly computing environment. With its clean interface, range of productivity tools, and customizable options, Ubuntu is an excellent choice for developers, students, and anyone who wants a hassle-free computing experience.
Ubuntu reset is a process that restores the default settings of Ubuntu to their original state. This process can be useful in cases where the system has become unstable or has been customized extensively, and the user wishes to restore it to its original configuration.
No, the default reset process will erase all user data and configurations. However, you can create a backup of your data and restore it after the reset process is complete. To backup your data, you can use an external hard drive, cloud storage service, or other backup solution.
I have nextcloud 12.0 running on ubuntu desktop 16.4 the system working as well
After rebooting my ubuntu I found that the nextcloud stop working
I am trying to start Apache2 service but nothing happened
This is the first time I reboot my server
I would recommend following the Nextcloud manual instead of 3rd party tutorials, unless you need to do something beyond what the manual covers. In this case, they walk you through step by step on Ubuntu.

On a side note: During Ubuntu installation, I was asked if I would like to have encryption turned on, which I confirmed. This led to issues with my ssh keys (which are then only readable, after I login first with a password). Not sure if this feature could also lead to similar problems with Nextcloud.
The official installation manual seems to mention various additional steps, but it is unclear to me if these are required when installing nextcloud via snap. My (naive) impression was, that snap would take care of more or less everything (which it did, up to the reboot).
One step further now. Executing the steps described in the installation manual under Apache Webserver Configuration ( _manual/installation/source_installation.html#apache-configuration-label) helped bring nextcloud back.
I still have not yet found the missing piece in order to have Nextcloud work properly immediately upon reboot of the system, without a manual restart of apache. Could this behavior be related to the fact that I have opted to encrypt my home directory when installing ubuntu server (see above). How could this be checked/fixed?
I installed nextcloud with snap and whten reboot ubuntu I realize that nextcloud not working.
My solution was to disable apache2
sudo service apache2 stop
I guess snap was going in conflict with apache2. Try this!
Now this worked for me, but my install is on Ubuntu 18 Desktop installed Nextcloud from the software manager, then configured the web cert for ssl.
Used above to disable apache2, as NicolasFM mentioned it is interfering with Nextcloud starting on boot.
Thanks a lot for creating this topic. It helped me this moment while I was struggling to get out of the apache server screen. A sudo service apache2 stop worked really well and instantly I got the nextcloud login screen. A refresh took me to the dashboard.
Background: I set up a ubuntu desktop and installed LAMP stack last week. I then went to do something else, and just got back to carry on today. Either I did not set mysql password, or I have forgotten what I typed in.
I use the root user on centos, and i do it on the folder it comes as default, i dont change any directories, and that worked for me 2 times already, but its good that you finally figured it out, sorry for the late response

This week, I wanted to check a Docker command within Docker itself. I have been working with the dockerd engine on my Windows WSL 2 installation. Although I had been working through the terminal in VS Code, I wanted to try using the Ubuntu shell.
I found I had 2 versions of Ubuntu installed, each with its own password, and later realized I needed to log into the WSL shell. I researched and located a helpful solution on Stack Exchange that I summarized for use again in the future.
I followed these steps for both versions of Ubuntu, and I was able to reset both passwords. Once I opened the WSL shell, I was able to use my Ubuntu 18.04 credentials to start dockerd and check the commands I needed.
