Ubuntu 26.10 can be installed from PowerShell as a separate WSL 2 distribution using the official .wsl image. This example is for an x64 Windows machine with WSL 2 already working.
When I checked the available distributions, Ubuntu 26.10 was missing from wsl --list --online. The official Ubuntu release directory provides an AMD64 WSL image that can be installed directly.
GCC 16.2 can be installed directly from the Ubuntu 26.10 repositories. On Ubuntu 24.04, the exact release can instead be built from source alongside the existing GCC 13 installation. This guide puts the package-based installation first, followed by the source build, then shows how to switch GCC and G++ together with update-alternatives for existing CMake projects.
Choose the installation section for your Ubuntu release. Ubuntu 26.04 LTS and Ubuntu 26.10 have different GCC packages: the catalog checked for 26.04 lists a development snapshot, while 26.10 provides GCC 16.2. These are installation instructions; the source-build starting machine has Ubuntu 24.04 on x86-64 and GCC 13.3.0.
(more…)When I tried to clone a Git repository from my Ubuntu laptop over SSH, the server asked for the git user’s password. I already had an Ed25519 public key on the laptop. Here is how to authorize that key on the server so Git can use it instead of asking for the remote account password.
git clone git@git.developernote.com:~/repositories/tradeclient.git
Cloning into 'tradeclient'...
git@git.developernote.com's password:
My Windows laptop became almost unresponsive. By the time I investigated, it was responding again. PowerShell revealed file-operation delays of 36 seconds around the time of the freeze. Here are the commands and the evidence, including what they could not establish.
Update: An offline CHKDSK follow-up below found and repaired NTFS metadata errors, without reporting bad sectors.
(more…)While changing a domain administrator’s password in Windows PowerShell on a domain controller, I ran into a paste problem with Read-Host -AsSecureString. Typing a password manually worked, but pasting into the hidden prompt left the variable empty. Reading the clipboard with Get-Clipboard and converting its contents to a SecureString worked in the same session.
This is the procedure I used. It changes the password of the currently signed-in domain account and requires its existing password.
(more…)My Windows 10 C: drive was almost completely full. Its capacity was only about 31.45 GB, while Disk Management showed another 18 GB of unallocated space on the same disk. Expanding C: looked straightforward, but a small recovery partition stood in the way. Then disabling Windows Recovery Environment failed because the drive was too full.
(more…)This guide explains how to add a graphical desktop to an Ubuntu 24.04 VPS and access it using Windows Remote Desktop. The setup uses XFCE, xrdp, and a regular Linux user. RDP connections travel through an SSH tunnel, with xrdp listening only on localhost.
