RetroArch emulator released version 1.15.0 a few days ago. Here’s how to install it in Ubuntu 22.10, Ubuntu 22.04, Ubuntu 20.04 and Ubuntu 18.04 via PPA.

The new 1.15.0 release feature steam support for macOS user, though macOS 10.13 or later is required. Also, it supports Apple’s native Gamepad protocol MFi, includes Vulkan video driver that is HDR capable for macOS users.

The new release also features Append Preset and Prepend Preset, allows to stack shader presets now on top of each other. Meaning user can mix various shader presets and then save it as a new preset.

Another big change is the alternative system to runahead – preemptive frames. Which, works by rerunning core logic to “rewrite history” before the current frame. Frames are only rerun when the controller state changes. Runahead is still available, and user can choose which one to use.

Ksnip 1.10.1 Add KDE Support for Scale Factor [Ubuntu PPA]

Last updated: March 16, 2023 — Leave a comment

Ksnip, the popular free open-source screenshot and annotation tool, released 1.10.1 version yesterday.

Ksnip is a Qt based screenshot tool with editing features, that works in Windows, macOS, and Linux on both Wayland and Xorg. It’s one of my top favorite applications for adding annotations in screenshot.

The app just released version 1.10.1 one day ago as the first point release for the 1.10 release series. It’s a small release with a new feature: KDE support for scale factor. Meaning it’s now working better in KDE desktop (such as KUbuntu, Ubuntu Studio) with different scaling factor.

Other changes include:

  • Fix drag and drop issue for Ksnip installed as Snap.
  • Fix sticker resizing issue when bounding rect flipped.
  • Show tab tooltips on initial tabs.
  • Fix for unnecessary scrollbars when a screenshot has a smaller size than the previous one
  • Fix that loading image from stdin single instance client runner side doesn’t work

How to Install KSnip 1.10.1 in Ubuntu / Linux Mint

Option 1: Snap package

The easiest way to install the tool in Ubuntu is using the official Snap packages. Simply open Ubuntu Software, then you can search for and install it via few clicks.

Install Ksnip via Ubuntu Software

Option 2: AppImage / Deb

The software project page also provides AppImage and Deb packages, as well as Windows and Mac OS packages for download under ‘Assets’ section:

Download Ksnip

For most Linux, you may download the non-install AppImage package, make it executable via right-click menu “Properties” dialog -> “Permissions” tab, and finally click run the package to launch it.

For Debian and Ubuntu based system, download the .deb package and install it by running command in terminal (press Ctrl+Alt+T to open terminal):

sudo apt install ~/Downloads/ksnip-*.deb

NOTE for Ubuntu 22.04, double-click installing this local deb via “Software Install” option may not work properly. It refers to the Snap package, rather than installing the local package.

Option 3: Ubuntu PPA (unofficial)

For those prefer Ubuntu PPA, here’s an unofficial repository with Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10 and Ubuntu 23.04 support.

Simply press Ctrl+Alt+T on keyboard to open terminal, and run the commands below one by one will add the PPA and install the screenshot tool from it.

sudo add-apt-repository ppa:ubuntuhandbook1/ksnip
sudo apt update
sudo apt install ksnip libkimageannotator0 libkcolorpicker0

Install the OCR plugin:

The OCR plugin is available to install as a separate package. It’s available to download at the link below:

Download OCR plugin

Click to expand the ‘Assets‘ section, download & install the .deb package for Debian and Ubuntu based system.

Uninstall Ksnip

For the snap package, simply click ‘uninstall’ button in Ubuntu Software.

For deb package, press Ctrl+Alt+T on keyboard and run the command below to remove it:

sudo apt remove --autoremove ksnip libkimageannotator0

And, remove the Ubuntu PPA (if added) by running command:

sudo add-apt-repository --remove ppa:ubuntuhandbook1/ksnip

Transmission 4.0.2 Released with Numerous Bug-Fixes [Ubuntu PPA]

Last updated: March 16, 2023 — 5 Comments

Transmission BitTorrent client got another bug-fix release for the new major 4.0.0 that was released a month ago.

The new Transmission 4.0.2 fixed the bug that some torrents thought they were magnet links, auto-add watch folder issue for macOS, broken speed limits for utp peers, and using announce-list when creating single-tracker private torrents.

The release also restored support for path.utf-8 keys in torrent info dictionaries, fixed potential crash when downloading from webseeds or receiving malformed piece data from peers.

There are also various other bug-fixes, including:

  • Fixed value of TR_TIME_LOCALTIME environment variable in torrent scripts.
  • Fixed display of IPv6 tracker URLs.
  • Added up / down arrows to upload / download badge info for macOS UI.
  • Fixed “Unrecognized colorspace number -1” error messages from macOS
  • Fixed per-torrent ratio display in main window in QT UI.
  • Fixed 4.0.0 ignoring -m/–minimized command line option.
  • See more about the changes, see github releases page.

How to Install Transmission 4.0.2 in Ubuntu / Linux Mint

Transmission does not provide official binary packages for Linux. Besides building from the source tarball, user can either use the universal Flatpak package or an Ubuntu PPA.

For those prefer the classic .deb package, this unofficial PPA has been updated with the latest packages for Ubuntu 20.04, Ubuntu 22.04, and Ubuntu 22.10.

The new web user interface depends on NPM (Node.js package manager). It requires internet connection while building process, but launchpad build farm does NOT have. Meaning so far the PPA package does not include new web UI via JavaScript, but the old web user interface for remote control is stilling working.

1. First, press Ctrl+Alt+T on keyboard to open a terminal window. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/transmission

Type user password (no asterisk feedback) when it asks and hit Enter to continue.

2. After adding the PPA, you can then launch Software Updater (Update Manager) and upgrade the system pre-installed transmission package to the new 4.0.2 release.

For Ubuntu based system without the BitTorrent client pre-installed, you may run command below to install it:

sudo apt update && sudo apt install transmission-gtk

You may replace transmission-gtk with (or add) following package:

  • transmission-qt – Qt user interface for KDE, LXQt, etc.
  • transmission-cli – command line interface.
  • transmission-daemon – the daemon for running in background, and access via webUI

Uninstall Transmission 4.0.2

You can choose to downgrade the BitTorrent client to system pre-installed version, by running command in terminal:

sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/transmission

Or, remove the software packages instead by running command:

sudo apt remove --autoremove transmission-gtk transmission-qt transmission-cli transmission-daemon

And remove the PPA repository either via “Software & Updates” tool by removing the source line under “Other Software” tab, or by running command:

sudo add-apt-repository --remove ppa:ubuntuhandbook1/transmission

That’s all. Enjoy!
