I have a raspberry pi 3b+ with raspbian 9.9 os (with 2gb swap). Today I am run `sudo apt-get update && sudo apt-get upgrade` and upgrade many things include gitlab to the new version `12.0.3-ce.0`. When I open local_ip:9999 on browser I seen errorpage `502 Whoops, GitLab is taking too much time to respond.` `sudo gitlab-ctl status` say all run, excluding grafana: `down: grafana: 1s, normally up, want up; run: log: (pid 963) 2411s`. in `sudo gitlab-ctl tail` printing many messages like `2019-07-03_20:49:03.28523 chpst: fatal: unable to run: /opt/gitlab/embedded/bin/grafana-server: exec format error` result of `file /opt/gitlab/embedded/bin/grafana-server`: `/opt/gitlab/embedded/bin/grafana-server: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, not stripped`. Is it ok? I doesn't understand how to fix a problem. Please, help.
