netopeer2 fails to install

[Nigel Hathaway]

Setting up netopeer2 (2.0.35-1ubuntu1) ...
/usr/share/netopeer2/merge_hostkey.sh: line 29: /dev/null: restricted: cannot redirect output
dpkg: error processing package netopeer2 (--configure):
 installed netopeer2 package post-installation script subprocess returned error exit status 1
Processing triggers for libc-bin (2.35-0ubuntu3.1) ...
Errors were encountered while processing:
 netopeer2
E: Sub-process /usr/bin/dpkg returned an error code (1)

Line 29 of that script is this:

PRIVPEM=`$OPENSSL genpkey -algorithm RSA -pkeyopt rsa_keygen_bits:2048 -outform PEM 2>/dev/null`

Line 34 has a similar thing.

The script aborts because of 'set -e' on line 3.

Workaround until fixed:

apt install -y netopeer2 sysrepo-plugind libyang2-tools || true
/usr/share/netopeer2/merge_hostkey.sh
/usr/share/netopeer2/merge_config.sh
apt install -f

Another problem: if you try and uninstall netopeer2, you get this:

Removing netopeer2 (2.0.35-1ubuntu1) ...
bash: /usr/share/netopeer2/remove.sh: No such file or directory
dpkg: error processing package netopeer2 (--remove):
 installed netopeer2 package post-removal script subprocess returned error exit status 127
dpkg: too many errors, stopping
Errors were encountered while processing:
 netopeer2
Processing was halted because there were too many errors.
E: Sub-process /usr/bin/dpkg returned an error code (1)

This is because it is trying to execute a script that has already been removed.
