Linux: Wickr Won't Open

Applies to:

If you are having trouble opening Wickr on your Linux device, please check your processor for AVX and AVX2 support by opening a Terminal window and typing in:

grep ^flags /proc/cpuinfo | sort -u | cut -f 2 -d: | sed -e 's/ /\n/g' | grep avx

This should list both if you have AVX and AVX2 support on this processor.

Alternatively, you can find your model name and number by typing in a Terminal:

cat /proc/cpuinfo

After getting your CPU model information from the command above, you can enter that model name and number into Intel's website to check compatibility. Under the Advanced Technologies tab, look for Instruction Set Extensions.

If you do not have AVX and AVX2 support listed here, you will need to uninstall the current Wickr version and install the candidate version instead, until we are able to resolve this issue.

You will need to type the following in the Terminal to install the candidate version of AWS Wickr. To change the app installed, change the final command to "wickrenterprise"

sudo snap install --channel=candidate wickrpro
