How do I find out which version of the Adobe AIR runtime I have installed on my Ubuntu system?
Please don't tell me to look at this article in the Knowledge Base, since the method reported there does not work. The file /opt/Adobe AIR/Versions/1.0/Resources/ApolloVersion does not exist.
Oh, stupid me, it is as simple as opening the Synaptic Package Manager and search for "adobe air": the installed version is shown there. At least in Ubuntu and at least if you installed it with Synaptic.
Anyway I'd like to know if there is a more general way (not relying on whether you installed it with synaptic) and it would be good to fix the knowledge base article with correct information
You could find the version of Adobe AIR installed on your system using the commandline as well:
dpkg -s adobeair (on Debian systems like Ubuntu)
rpm -q adobeair (on RPM based systems like Fedora and Opensuse)
