How to Fix Python Pip Install Error in Ubuntu 24.04

Last updated: March 26, 2024 — 1 Comment

When using pip command to install a Python package in Ubuntu 24.04 will output “error: externally-managed-environment“. Here are a few workarounds to ‘fix’ the issue.

As the terminal output shows you, it’s the change due to PEP 668. Since Ubuntu 23.04, it recommends Python-specific package management tools (e.g., pip) to install packages using a virtual environment, to avoid conflicts to packages installed by OS package managers. Though, user can still force pip to install into interpreter’s global context just like before.

Kooha Screen Recorder 2.3.0 Has Better Area Recording Support

Last updated: March 25, 2024 — Leave a comment

Kooha, the small free open-source screen recording app, release new 2.3.0 version a few days ago.

Kooha is one of the first apps support Wayland, the default display server in recent Ubuntu and Fedora workstation releases. Since GNOME’s built-in screenshot/screencast tool does not support recording audio, it is a good alternative to record full screen or rectangular area with microphone and desktop audio support. And, it can record your desktop screen into WebM, MP4, GIF, and Matroska formats.

In last 2.2.x release series, Kooha added new area selection UI for better Wayland support. In the new 2.3.0 release, the area selection window now is resizable, so you can have a bigger view when selecting recording area. And, previous selected area is now remembered to make it easy to redo recording last area.

[Quick Fix] Enlightenment Xorg Session is Missing in Ubuntu 24.04

Last updated: March 23, 2024 — Leave a comment

After installed Enlightenment desktop in Ubuntu 24.04, the classic Xorg session is missing from the login screen. And, here’s a quick fix for it.

Enlightenment released version 0.26.0 last year with experimental Wayland session support. Which is however missing the Xorg session in the login screen due to bug.

Why the Enlightenment Xorg Session is missing

Ubuntu now finds the desktop sessions from both /usr/share/wayland-sessions/ and /usr/share/xsessions/ directories. And, the former one has higher priority!

Enlightenment 0.26.0 installs its session entries in both directories with same name. In the case, only the one for Wayland is in active, while another for Xorg is ignored and hidden from login screen.

Get Rid of thunderbird.tmp in Ubuntu 24.04 Downloads Folder

Last updated: March 23, 2024 — 2 Comments

For Thunderbird users, there will be a thunderbird.tmp sub-folder in Downloads in Ubuntu 24.04. Here are the workarounds to get rid of it!

As you may know, the Thunderbird package in Ubuntu 24.04 is a Snap package that runs in sandbox! Due to this switch, the “thunderbird.tmp” sub-folder will be created on every launch (even after you deleted it) of the email client, in user’s Downloads folder.

According to this discussion page:

“This is a tmp dir to store files you choose to open directly from Thunderbird. The snap can’t use the usual (insecure) /tmp location so had to choose something widely available so other apps can open the files if chosen.“
