This is a guide on how to install WireframeSketcher on Ubuntu/Debian or on another distribution that uses APT and supports .deb packages.
First, make sure that you’ve downloaded the appropriate .deb package from our download page. Note that from version 6.0.0 only 64-bit packages are provided, so make sure this is the architecture of your platform.
You should normally be able to install the .deb package directly, simply by double-clicking it to launch the appropriate installation program.
Some of the newer versions of Gnome Software have a bug that prevents it from installing .deb packages directly. It fails with with an error that says: “this file type is not supported”. In this case use one of the following installation methods:
- Install gdebi tool and then open and install the .deb file using it.
- Use dpkg and apt command line tools as follows:
sudo dpkg -i /absolute/path/to/deb/file sudo apt install -f
Once WireframeSketcher is installed you can launch it from Applications > Graphics menu, or by searching for it in the launcher, or alternatively by launching the /opt/WireframeSketcher/WireframeSketcher executable from the command line.
Updating
Note that once the .deb package is installed it will register WireframeSketcher’s repository that will allow the APT system to auto update WireframeSketcher when a new version is available.
The APT repository and the .deb package are signed using WireframeSketcher’s GPG key with the following fingerprint:
631C A1B9 A15F 3EE0 ABE2 4B98 98EB 2367 8D44 ED16
Peter Severin <peter at wireframesketcher.com>If you have an older installation of WireframeSketcher then you might see the following error when trying to update:
GPG error: http://wireframesketcher.com/debian Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 98EB23678D44ED16In this case just download the latest version of .deb package from our website and reinstall it. This will register the new GPG key on your system and future updates will work correctly.
