[Workaround] Fix Nautilus Admin Not Working in Ubuntu 21.04

April 14, 2021 — Leave a comment

Use GVfs admin backend to open Nautilus file browser or Gedit text editor with root permission? It’s not working in Ubuntu 21.04.

When you run nautilus admin:// or gedit admin:// to open folder or document with root, it won’t work and output an error:

GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Unix process subject does not have uid set

The error also occurs when using nautilus-admin extension to enable ‘open as root’ context menu.

The issue is caused by a gvfs commit to fix flatpak app network permission requirement problem. To get rid of the error (see bug), reverting just that one commit could be a workaround.

Method 1: Install old GVfs from Ubuntu 20.10 repository:

You can download & install the gvfs .deb packages for the previous Ubuntu 20.10. And here are the links for 64-bit system:

gvfs_1.46.1-1ubuntu1_amd64.deb

gvfs-libs_1.46.1-1ubuntu1_amd64.deb

gvfs-fuse_1.46.1-1ubuntu1_amd64.deb

gvfs-daemons_1.46.1-1ubuntu1_amd64.deb

gvfs-common_1.46.1-1ubuntu1_all.deb

gvfs-backends_1.46.1-1ubuntu1_amd64.deb

Grab the 6 packages, then open terminal (Ctrl+Alt+T) and run command to install all of them:

sudo apt install ./Downloads/gvfs*.deb

Method 2: repack GVfs to revert the commit:

If you don’t want to downgrade gvfs, just rebuild it without the commit. To make things easy, I’ve uploaded into this PPA.

1. Open terminal either from system app launcher or by pressing Ctrl+Alt+T on keyboard. When it opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/gvfs

2. Then install the patched version of gvfs via command:

sudo apt install gvfs=1.47.91-2ubuntu1

3. Finally remove the PPA via command:

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

How to Restore GVfs to stock version:

If you change mind, and want to revert it back, simply run command in terminal:

sudo apt install gvfs=1.47.91-1ubuntu1

Quiet Audio Fade – Get The Quietest Volume Level for Work

April 13, 2021 — Leave a comment

Quiet Audio Fade (aka Quite AF) is a small applet slowly reduces the volume on your computer over time, letting you find the quietest level that works.

It’s f.lux for your ears!

The tool is written in Go programming language, and it works in Windows, Linux, and Mac OS.

It works as a system tray indicator with only a few menu options. The first option shows the current tool status (ACTIVE or PAUSED) along with the volume level in number.

When it’s in ACTIVE mode, it slowly decreases your system volume bit by bit with time interval set in “Speed” option. Higher intervals mean a longer, more subtle decrease.

Eventually you’ll notice the sound is a tad too low and you’ll increase the volume, which will disable Quiet AF and leave your volume at the perfect level – not too loud, not too quiet!

How to Get Quiet Audio Fade in Ubuntu:

Besides building from source tarball, the applet offers single executable file in its project page:

Quiet AF Releases

Grab the package for Ubuntu, and give executable permission in file’s Properties dialog.

You’re finally able to start it via command in terminal (Ctrl+Alt+T):

./Downloads/QuietAF_Ubuntu

If you prefer the applet, you can move the executable file to /usr/local/bin, manually create app shortcut, or add it as startup application.
