I tried to upgrade v4.7.2 to latest version but got following msg:

An error occurred while uninstalling session context was:(profile=profile, phase=org.eclipse.equinox.internal.p2.engine.phases.Uninstall, operand=[R]com.wireframesketcher.studio.product_root.gtk.linux.x86_64 4.7.2.20161214-1049 --> null, action=org.eclipse.equinox.internal.p2.touchpoint.natives.actions.CleanupzipAction). Backup of file /opt/WireframeSketcher/WireframeSketcher failed. File that was copied to backup could not be deleted: /opt/WireframeSketcher/WireframeSketcher

What to do now?

Hi,

What method did you use to install WireframeSketcher? We supply .deb packages for Ubuntu/Debian which also registers WireframeSketcher repository. You should be able to install the new version of WireframeSketcher using system update.

sudo dpkg -i WireframeSketcher-4.7.2_amd64.deb

This is Ubuntu 16.04

Do you mean that I can upgrade manually:

download WireframeSketcher-4.7.3_amd64.deb

exit WireframeSketcher-4.7.2

install new version:

sudo dpkg -i WireframeSketcher-4.7.3_amd64.deb

Do I need to set the license key again?

In this case system update should install version 4.7.3 of WireframeSketcher. Have you tried it?

You should be able to update WireframeSketcher as part of system update:

sudo apt-get update

followed by

sudo apt-get upgrade

That worked, thanks.

(I got the error while I was trying to update using WireframeSketcher UI Help / Check for updates.)
