I am running EOS 5.1

No LSB modules are available.
Distributor ID: elementary
Description:    elementary OS 5.1 Hera
Release:    5.1
Codename:   hera

I am currently experiencing a problem signing odt documents in LibreOffice.* I have upgraded Libreoffice using a ppa, but this has not fixed my perceived issue. (6.0.7 --> 6.3.4) My next step in troubleshooting is to update libnss3.

current version:

apt-cache show libnss3
Package: libnss3
Architecture: amd64
Version: 2:3.35-2ubuntu2.7

according to bugzilla There were several bug fixes in 3.36 alone. The current stable version is 3.45(?)

Does anyone have a suggestion on how I could update this package?

*I can sign new documents using my p12 cert stored in ~/.pki/nssdb and everything is fine. the problem occurs when I must sign a document that was previously signed by someone else, my signature shows as "invalid".

You can download the .deb package from libnss3_3.45-1ubuntu2_amd64.deb . After that, you can use Eddy to install it.

Before installing the package:
libnss3 is already the newest version (2:3.35-2ubuntu2.7).

After installing it:

vlad@lenovo-y530:~$ apt list libnss3 -a
Listing... Done
libnss3/now 2:3.45-1ubuntu2 amd64 [installed,local]
libnss3/bionic-updates,bionic-security 2:3.35-2ubuntu2.7 amd64
libnss3/bionic 2:3.35-2ubuntu2 amd64

Please let us know if this solves the signing issue.

    what's eddy? can't I just use dpkg -i libnss3_3.45-1ubuntu2_amd64.deb Jan 17, 2020 at 18:19
  • I was able to install the newer version of the nss libraries using dpkg. apt list libnss3 Listing... Done libnss3/now 2:3.45-1ubuntu2 amd64 [installed,local] This however did not resolve my signing issue. Jan 17, 2020 at 18:36
  • Eddy is just a simple GUI app used to install debs. Not everyone knows about dpkg or are comfortable using bash. Anyway, I'm glad I could help with your problem a bit. Now I recommend closing this question and it would be better to ask for help at ask.libreoffice.org/en/questions, since your issue is not an elementary OS one.
