Something went wrong when updating Synergy app and now it's impossible to do anything with the package: the dreaded (at least for me) "Sub-process /usr/bin/dpkg returned an error code (1)". I copy the log when trying to purge it:

I tried all the basic troubleshooting stuff like dpkg --configure -a, sudo apt -f install, apt-clean and several forms of deletion without success.
Thank you in advance.

Follow up. Sorry for the delay. I ended up leaving the city for several days. I got this:

~$ export SYNERGY_LOGGER=DEBUG ~$ cat /var/lib/dpkg/info/synergy.prerm #!/usr/bin/env sh

sudo ./opt/Synergy/synergy-service --uninstall

I don't know if this is of help. Thank you.
