Porteus 3.2x Newbie Install Guide Pt. 1-2

Post#1 by yldouright » 26 Feb 2018, 20:22

This is a more fully explained installation guide that extends to configuration and troubleshooting after the install. I have limited its scope to version 3.2x since I am referring only to personal experience:

Part 1 - Getting a clean start

Step 1 - Download a Porteus .iso and its checksum from any of its mirrors. Select the .iso appropriate for your hardware. If you are unfamiliar with your hardware, enter your bios, write down what you see and use your search engine to learn what you have. An .iso is a disk image and the checksum is used to verify the downlaod wasn't corrupted.
Step 2 - Once you have the .iso, use a checksum utility to verify the file. There are many ways to do this, they don't cost anything and they all work. It's a good practice to do this to rule out any potential problems later.
Step 3 - Burn your .iso to your optical media or mount the .iso and copy it to any other removable drive. If you burn optical media, verify the burn. If you copied the file, do a disk check on the volume. We do this to rule out potential causes of later problems.
Step 4 - Boot from the media you just prepared. You may need to interrupt your boot procedure to select the right media or change the setting in your bios to have that image boot. Once again, look this up if you don't know how to do this.
Step 5 - Monitor the messages as the software loads. Many potential problems are exposed or hinted at during this process. You should see the Porteus 'blue page' which allows you to select how you boot. Some boot options can help workaround and identify problems you encounter using Porteus but for the time being, boot to RAM. It will take longer to boot into the desktop than the default setting but it will generally allow you more flexibility in troubleshooting and testing the OS.
Step 6 - The software should load to a fully working OS desktop. Test all the functions and software that matter to you before installing the OS. Make notes of any issues and see if solutions are available prior to installing the software. Prepare these in a handy location for when you need them.
Step 7 - If everything works as it should, you're either really lucky or running a version of Porteus 3.1 :) Seriously, if you tried USM you noted that the databases fail to update properly and in some cases break your system. A big thanks goes to @Bogomips for his solution to this. He constructed three scripts (sesm.sh, safm.sh and badm.sh) found here, that add and purge depositories so USM works properly.
Step 8 - Once you are confident that you can get and run what you need on your system, you can begin making a permanent installation. The procedures will differ slightly depending on where and how you will install it and those will be covered in part 2 of this tutorial.

In Part 1 we did the preliminary investigation of the Porteus OS prior to the install. You should have identified any problem hardware and discovered any software unavailable to your desired build so now we’re ready to copy the OS to the media and complete the installation.

Part 2 – Getting the OS where and how you want it.

Step 1 – You’ve booted your Live OS Install disk and are now logged on to the desktop. You should know which drive you are installing on. If you have multiple drives in your box, make sure you know which is which. Without this information you may overwrite things you don’t want to. Once you know which drive you want to install on, go to your application menu and locate the “Porteus System Installer”. One thing you need to understand is that this installer does not actually install a working system. It only copies the working OS to your disk. To get an OS that boots you will need to activate it but we’ll get to that later. You need to decide if your install will stand alone or share the disk with another OS.
Step 2 – If your install will stand alone, it is recommended to format the drive with a Unix type filesystem. I prefer the default “ext4” filesystem for Porteus but you may choose any you wish. If you choose a Windows/DOS filesystem, you will need to use the Windows script at the end of the install instead of the “Porteus-installer-for-Linux.com” script. Gparted is the application Linux typically uses to create the filesystem. When your drive is ready, it will show up in the installer list. If it doesn’t, just select ‘mount drive’ to find it and select it. Click “Next” to start the copy process.
Step 3 – You will then be presented with a dialog asking you to install the bootloader. Unless you plan to use a separate bootloader, you must select both those checkboxes for your installation to boot. After a few minutes, you will be presented a terminal to input the install script. Type Porteus-installer-for-Linux.com to run the script if you’re installing on a Unix filesystem. If it’s a Windows filesystem, type Porteus-installer-for-Windows.com.
Step 4 – If all went well, you will receive a message in the terminal asking you to type “ok” to complete the installation. Do so and reboot. If you have only one drive in your system; flash drives, media cards, optical media and the like are also drives; and it still doesn’t boot, review the instructions again because I’m pretty confident this is on you. If you booted into another OS or the OS didn’t boot, you may need to use the bios boot interrupt function key to select the right drive or go into your bios to change your boot order.
Step 5 – If you have decided to share your drive with another OS, you will have to wait for Part 3 for further instruction but if not, Porteus will present you with its soon to be familiar blue splash screen. You'll have time to set your boot choice but this and other boot parameters are configurable later in the OS. You should note how much faster the boot happened from the hard drive. Okay, now you’ve got a stripped down system and you need to get your software but wherefrom? Let’s enable your network.
Step 6 – On the upper right hand side of your display you will find the network icon. You may wish to set your passwords prior to enabling and configuring your network but it’s not a requirement to get access to USM depositories. Passwords for your root and guest accounts are done from the “Application:System Tools:Porteus Settings Centre” menu. Click the “lock” icon there to enter the change. The default passwords for root and guest accounts are “toor” and “guest” respectively. Once your network is enabled you need to update the USM depository database.
Step 7 - USM is the Slackware equivalent of Synaptic on Debian based Linux. Unfortunately, it’s not working so great since Porteus v_3.1 but there are usually alternative ways to get things done in Linux. Click on the USM icon on the middle left side of the top menu bar. You should get a notice of missing database files. Do NOT use USM to update your databases, we’ll use a terminal but before that, we need to check our database sources. Fortunately, Porteus Forum member Bogomips wrote some scripts to do this for us and they are included below:

and badm.sh script codes.

Code: Select all

badm.sh 3 salix >> .usm/badmirrors.txt
In order to use the badm.sh script properly you need to create a directory to store the output prior to running it. Create a hidden directory inside the usm directory by going there as root, opening a terminal and typing mkdir .usm. Its use is optional . Open terminal in the directory where you saved those scripts. Enter su and your root password to run these scripts. The root password is “toor” if you didn’t change it as described earlier. Type sh sesm.sh in the terminal. This script should prevent source database faults when you run the next command, usm -u all. The terminal should show the depositories updating, wait until they’re done. If there were no issues, you should be able to use USM to search for and install your desired software.
Step 8 – If you experienced broken/missing/corrupted databases, you will need to run the other two scripts above in the following order; sh safm.sh will select and promote the good depositories and if you created the hidden ".usm" directory, sh badm.sh will purge and remove the worst ones and save them in a file in the event they can be redeemed later. Run the usm -u all command once again to correct the previoius database errors. That’s it for Part 2, Part 3 gets into setting up your OS for problem free operation and provides software recommendations for common computer functions.
