P1 Mode signal 11 on Ubuntu 19.04

[katakombi]

When I run udocker from Ubuntu 19.04 with kernel 5.0 I get a Signal 11:

./udocker pull alpine:latest
./udocker create --name=a alpine:latest
./udocker run a sh
proot info: vpid 1: terminated with signal 11

This happens when P1 mode is being used. P2 still seems to work fine when forced using

export PROOT_NO_SECCOMP=1

Edit: there might be related issues proot-me/proot#106
Could someone please confirm or give further details?

This issue seems fixed in the devel branch.

[katakombi]

Did you update the proot static binary? Gonna recheck...

[katakombi]

Confirmed to be fixed! Congrats & thanks! I'd just be interested if the issue was with proot after all...

[jorge-lip]

Yes it was recompiled. The tarball used by the devel branch is newer.

[katakombi]

Alas, proot didn't solve the underlying bug (probably proot-me/proot#106)
This issue can still occur on other kernels/distros. I found it on Fedora 31 with kernel 5.3.11. Useless to open issues for udocker, just adding this as a note!

Hi,
Can you try with the latest development version

[katakombi]

I don't have my VM with Fedora 31 any longer. So I'd test it but it might take a while...

I am experiencing the same issue here with latest udocker, tried different images but all fail.
