When using the web UI, the error is:

libreoffice-core is at 2d9e0a7ffa29a0882b92c55e90189e509124e2de

But code from a few days ago had the same problem.

PDFExport::Export throw:

N3com3sun4star3uno9ExceptionE msg: NSS_NoDB_Init failed with SEC_ERROR_PKCS11_DEVICE_ERROR (-8023) at /home/hub/Documents/Collabora/cool-dev/libreoffice-core/comphelper/source/misc/hash.cxx:87

[hfiguiere]

I see two problems:

1. it fails, and that looks like a config problem (possibly on my side), but the failure is obscure. I had to dig deep and trace to get the exception above.
2. the download hang. I think the API response should have been terminated possibly with an HTTP error code. Similarly in the web UI there is no error either. Just nothing.

[hfiguiere]

The lack of /dev/random and /dev/urandom in the jails seems to be the reason.

[hfiguiere]

A workaround is to build core with --with-tls=openssl. At least in a dev setup this works.

[hfiguiere]

I wonder if this is not #5088 also.

[caolanm]

If this still reproduces, and seeing as step 1 is "Build CODE", is there output from:

make check-for-system-nss

in online?

(core needs to be built using --without-system-nss for nss to work in chroot jail the above attempts to check for that)
