Julia 1.3.1 works on my ubuntu 18.04, but julia 1.4.0 do not.

[krcabrer]

I'm learning julia.

A time a go I install julia 1.3.1 and is working fine on my ubuntu 18.04 platform,
(Linux KenServ 5.3.0-45-generic #37~18.04.1-Ubuntu SMP Fri Mar 27 15:58:10 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux) but when I try julia 1.4.0 this happens:

Invalid instruction at 0x7f97e131e0f8: 0x66, 0x0f, 0x3a, 0x0f, 0xc0, 0x08, 0x0f, 0x83, 0x61, 0x05, 0x00, 0x00, 0x48, 0xc1, 0xe0
