Symptoms
When attempting to install the Jetbackup software the installation does not complete. When reviewing logs within the directory "/usr/local/jetapps/var/log/jetapps" you find the following error:
your CPU is missing AVX instruction set flag
** your CPU is missing AVX instruction set flag, Please enabled it and then try again **
Description
Newer version of JetBackup use MongoDB 6.0+ which require the CPU to support certain instruction sets, specifically AVX or AVX2. Most CPUs after 2011 do support these instructions, however the error above indicates that the server running into the issue does not.
Workaround
You can verify if your CPU has this flag by using the lscpu utility, the command below will list the Flags for the CPU on the server:
lscpu | grep Flags
If the AVX flag is not present, the next step would be to contact your server host. If you are using a Virtualized server such as VPS it may be possible for your host to add this capability. If you have a Dedicated Server however you will need to work with your server host on next steps to get this functionality added.
