How to Install DevToys in Ubuntu:

The new release provides official .deb packages and portable tarball for Linux, which are available to download at the link below:

For the command line tool, select download either devtoys.cli_linux_x64.deb for AMD/Intel platform or devtoys.cli_linux_arm.deb for ARM devices (e.g., Raspberry Pi).

And for graphical tool, download either devtoys_linux_x64.deb for AMD/Intel, or devtoys_linux_arm.deb for ARM. Then, install by running command in terminal (Ctrl+Alt+T):

sudo apt install ~/Downloads/devtoys_linux*.deb

NOTE: The 2.0 preview package supports Ubuntu 22.04 and Ubuntu 24.04. In my case, it does NOT launch in Debian 12 and Fedora 40 due to missing run-time libraries.

In Ubuntu, it has launching issue due to permission issue. By starting from a terminal window, you’ll see the following error:

bwrap: setting up uid map: Permission denied

** (DevToys:17289): ERROR **: 00:35:39.254: Failed to fully launch dbus-proxy: Child process exited with code 1
Aborted (core dumped)

To workaround it, simply run as root via sudo devtoys command.


To remove DevToys installed via .deb package, use command:

sudo apt remove --auto-remove devtoys
