There might be two issues here which combined are a huge usability mess:
WickrMe is responsible: The WickrMe developer might have decided to enable geographic IP blocking (blocking some countries and perhaps Tor, VPNs, etc.) or only allowing specific geographic areas (specific countries). Not allowed / blocked areas would be refused from snap.
snap is responsible: At the same time, snap in these cases does now show a proper error message in case of geographic IP blocking.
This is a similar case for a similar application which can be seen in snap web store but when attempting to download it will fail.
Wickr Software is subject to the export laws of the U.S. and other countries, which may affect your ability to download and/or install our software from our site or various app stores. See Wickr | Terms of Service for more information.
My exit node was Norway. I don’t think norway is on the list of US export restrictions. I responded and hopefully that elevate the issue and get a tech person in.
Meanwhile I’m working wiki instructions for manual snap install:
A big annoyance in the need to download from non-whonix and file transfer. I wish there were a (trustyworthy) mirror or something that could be done from within whonix. The snap webpage doesnt seem to allow direct downloads.
I have just had this post come through. I may be able to add something. I run Zorin (debian based) on another pc. For some reason wickr stopped working on that machine telling me that it needed to be updated but I couldn’t update it, there was no method. Anyway after research it turned out that this was a debian problem. The solution was to install, via terminal the ‘back channel’ version of wickr. This worked on a couple of my pcs. I don’t have the commands for this handy, and I have no idea if it will work on whonix, but it was a terminal installation that works fine for me.
Later on today I will find the commands and try it on whonix. It may or may not help and what I talk about could probably be searched for anyway.
