How to Install GIMP 2.10.24 in Ubuntu:
Method 1: Install GIMP via the universal flatpak package:
If you’re OK with the flatpak package which runs in sandbox, open terminal and run following commands one by one to install it:
1. Firstly add PPA for updated Flatpak package (required for Ubuntu 18.04 only):
4. Finally install GIMP flatpak package via command:
flatpak install flathub org.gimp.GIMP
NOTE: as flatpak runs in sandbox, it takes much more disk space for run-time libraries.
5. (Optional) If you want to remove the package, run command:
flatpak uninstall org.gimp.GIMP
Method 2: install GIMP via Ubuntu PPA:
For those prefer the classic .deb packages, the unofficial PPA has made the new release packages for Ubuntu 20.04, Ubuntu 20.10, and Ubuntu 21.04.
Due to compile issue, the package for Ubuntu 18.04 is stuck at v2.10.22 at the moment.
1.) Open terminal from system application launcher. When it opens, run command to add the PPA:
sudo add-apt-repository ppa:ubuntuhandbook1/gimp
Type user password (no asterisk feedback) for sudo prompts and hit Enter to continue.
2.) If an old version of GIMP .deb package was installed, upgrade it via Software Updater (Update Manager) utility.
or run apt commands in terminal to install GIMP:
sudo apt install gimp
If you’re going to upgrade the image editor from command line, I’d recommend to RUN this command instead, so to also install the updated dependency libraries.
sudo apt upgrade

GNU Emacs text editor 27.2 was released as a new maintenance release.
Emacs 27.2 is a bug-fix release with no new features. According to the changelog, it changed the behavior of the user option ‘resize-mini-frames‘. If set to a non-nil value which isn’t a function, resize the mini frame using the new function ‘fit-mini-frame-to-buffer’ which won’t skip leading or trailing empty lines of the buffer.
Emacs now ignores modifier keys when IME input is used. By default, pressing Ctrl, Shift, and Alt keys while using IME input will no longer apply the modifiers to the produced characters, as there are IMEs which use keys with modifiers to input some characters. Customize the variable ‘w32-ignore-modifiers-on-IME-input’ to nil to get back the old behavior.
And the user option ‘tramp-completion-reread-directory-timeout’ is now obsolete.
How to Install Gnu Emacs in Ubuntu:
For those prefer the classic apt repository, keep an eye on the Kevin Kelley’s PPA, though it’s not been updated at the moment of writing.
Emacs is also available as the containerized Snap package, which is however at version 27.1 at the moment.
The community maintained Flatpak package has built Emacs 27.2 for Linux users. Ubuntu 20.04 and higher users can open terminal and run following commands one by one to install it:
Install flatpak framework if you don’t have it:
sudo apt install flatpak
Add flathub repository which hosts the flatpak packages:

The free and open-source BitTorrent client qBittorrent 4.3.4 was released. Here’s how to install it in Ubuntu 20.04, Ubuntu 20.10 via PPA.
qBittorrent 4.3.4 reworked the sorting logic. To get the old sorting order for the “queue number” column, first sort on the “Completed On” column and then sort on the “#”(queue number) column.
The new release now requires Qt >= 5.12. Ubuntu 18.04 is no longer supported via the official PPA due to outdated system libraries. You can however get it via the flatpak package since it gets most run time libraries bundled.
Add ability to prioritize selected items by shown file order.
Allow tab to escape the text box in “Edit trackers” dialog.
Support sub-sorting in Transferlist.
Expose ToS setting from libtorrent.
Improve tracker entries handling.
Enlarge “speed limit” icon slightly.
Don’t prevent system sleep due to errored torrents.
Use stable sorting in transfer list.
Apply “Hide zero/infinity values” to “Time Active”, “Down/Up Limit” and ETA columns.
Fix potential out-of-bounds access.
Add a 3-Hour graph.
Add option to disable icons in menus.
Improve detection of filename extension of audio/video files.

The Audacity audio editor 3.0.0 was released a week ago as the new major release. Here’s how to install it in Ubuntu / Linux Mint via Flatpak package.
Audacity 3.0.0 features new all-in-one-file aup3 project file format, improved ‘Noise Gate’ effect, new ‘Label Sounds’ analyzer, and over 160 bug-fixes.
Why Flatpak?
The distribution’s build and Ubuntu PPAs are mostly “incorrectly built packages” as they are built against the wrong wxWidgets (3.0.x), however Audacity 3.0.0 requires wxWidgets 3.1.3.
Though I’m not a fan of the containerized Flatpak package, it’s so far the only ‘correctly’ build binary package since the Snap is still under testing.
Install Audacity 3.0.0 via Flatpak:
Firstly open terminal from system app launcher. When it opens, run following commands one by one.
1.) For Ubuntu 18.04, add the PPA for updated version of Flatpak framework:
The flatpak package won’t replace the classic deb package. If you have more than one app icon in launcher, either remove Audacity installed via apt, or launch Audacity Flatpak via command in terminal:
flatpak run org.audacityteam.Audacity
Remove Audacity Flatpak package:
To remove the software installed via flatpak, simply run command:
Mozilla Firefox 87.0 was released today with further efforts on improving user privacy.
Firefox 87 introduced SmartBlock, a new intelligent tracker blocking mechanism for Private Browsing and Strict Tracking Protection Mode. By providing local stand-ins for blocked third-party tracking scripts, you’ll encounter less website breakage while fully protected from trackers.
As today’s web is on the way to becoming https-only and browsers are taking steps to improve user privacy, the 87 browser release introduced new default HTTP Referrer policy instead of ‘no-referrer-when-downgrade’.
It’s ‘strict-origin-when-cross-origin‘ which will trim user sensitive information like path and query string in the URL to protect privacy.
Other changes in Firefox 87 include:
New locale: Silesian (szl)
Improved “Highlight All” feature on Find in page.
Full support for macOS built-in screen reader, VoiceOver.
Disable the Backspace key for browsing back.
Various security fixes.
How to get Firefox 87 in Ubuntu:
For all current Ubuntu releases, the new Firefox package will be published in Ubuntu security & updates repositories in the next few days.
At that time, you can easily update the web browser through Software Updater (Update Manager)
For those who can’t wait, go to the release page which also includes a download button:
