I am trying to upgrade upsource from 1.1781 to 2.2197 in a CentOS virtual machine.
I followed the procedure in https://upsource-support.jetbrains.com/hc/en-us/articles/207242085?input_string=upsource+upgrade and the following error happens at US start:
[Upsource Error] Failed to start JetBrains Upsource 2017.2 due to unexpected exception: Native random generator does not seem to have enough entropy for JetBrains Upsource 2017.2 to start.
[Upsource Error] You can fix it by switching to PRNG (with -Djava.security.egd=/dev/zrandom) or by reconfiguring your operation system to provide more random bits.
I saw your https://hub-support.jetbrains.com/hc/en-us/articles/206545269-Hub-hangs-up-on-start page and tryed to follow the second option, but I am not able to run rng-tools in my centos (https://bugzilla.redhat.com/show_bug.cgi?id=893342 )
I do not really understand the first option: where the -Djava.security.egd=/dev/zrandom ; OR parameter must be placed?
We are off service until this is resolved, so I appreciate any help.
