Difficult to debug without the output of "See "systemctl status redis-server.service" and "journalctl -xe" for details."

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[oletechie (marknlin)]

I tried to install ntopng-blake. failed to install after 97% done. Same failure as above.

[Strix (nightstrix)]

I just turn off vpn, and all worked fine.

I used VPN client from privateinternetaccess.com and theirs standard client for Linux

Dupe of https://bugs.launchpad.net/ubuntu/+source/redis/+bug/1786710?

I also had to turn off my VPN (ProtonVPN with their official command line client) and the install worked. Otherwise had a long timeout as others have stated. Output of `journalctl -xe` attached.

[Expired for redis (Ubuntu) because there has been no activity for 60 days.]

[Alexander Saers (alex-saers)]

I also hit the same error. After some investigation I found out what the problem was. It looks like redis is configured to bind to localhost over both ipv6 and ipv4.

On my system I had disabled ipv6 via grub "ipv6.disable=1" therefore the configuration was invalid and redis did not startup.

One fix is to change the file /etc/redis/redis.conf
- bind 127.0.0.1 ::1
+ bind 127.0.0.1

and then try to finish the installation with
apt install -f

Hope this helps.
