03:18 <FromGitter> <shootingfly> I meet a problem when doing `shards install` in docker. Can anyone help me? ⏎ ⏎ It works in my MacOS, ⏎ ⏎ ```code paste, see link``` ... [https://gitter.im/crystal-lang/crystal?at=62427a8bc61ef0178e968026]

03:31 <FromGitter> <Blacksmoke16> @shootingfly what happens if you run like `cat /dev/urandom | base64 | head -c 5` on that server

03:34 <FromGitter> <Blacksmoke16> pretty sure the gist of it is your kernel is too old ⏎ ⏎ > getrandom() was introduced in version 3.17 of the Linux kernel.

03:36 <FromGitter> <Blacksmoke16> https://crystal-lang.org/reference/1.3/platform_support.html#tier-1 assuming the `2.6.18+` references the linux kernel version supported, that either needs updated, or this is a bug and something needs to be done to handle this

03:50 <FromGitter> <Blacksmoke16> okay yea, it exists but the syscall doesnt so it fails. I'd prob file an issue for it

03:50 <FromGitter> <Blacksmoke16> outcome is either a) update min required linux kernel version, or b) fallback on something if this syscall isn't implemented

07:01 <FromGitter> <moe:busyloop.net> @shootingfly: fwiw, if you don't want to upgrade your jenkins host - jenkins has great support for remote agents. you can spin up a VM with a recent kernel on DO or vultr and have jenkins use it to perform your build in minutes https://www.jenkins.io/doc/book/using/using-agents/

07:28 <FromGitter> <shootingfly> I degrate my Crystal version from 1.3.3 to 1.2.2. Now it works. It is also wrong in v1.3

07:30 <FromGitter> <shootingfly> Shootingfly @shootingfly 15:28 ⏎ @Blacksmoke16 @moe:busyloop.net It works well now. I degrate Crystal version from v1.3.3 to v1.2.2 . It is also wrong in v1.3.0.

I will ask my ops partner to try it.

07:34 <FromGitter> <moe:busyloop.net> yup, that said, upgrading your jenkins host may also be a good idea in general. ⏎ your kernel is 9yrs old - crystal is likely not the only software that will complain ;)

I always upgrade softwares to the latest. But I have no permission to upgrade jenkins and kernel, it is my partner'job. [https://gitter.im/crystal-lang/crystal?at=6242b81b6b91242320582db2]

12:47 <FromGitter> <Blacksmoke16> Oh interesting

12:47 <FromGitter> <Blacksmoke16> Must be a regression then, so definitely file an issue

13:57 <FromGitter> <moe:busyloop.net> mh. i don't think crystal team should spend extra work to support ancient kernels. ⏎ apparently `getrandom` was added in 2017; https://lwn.net/Articles/711013/
