I'm still very much a novice when it comes to Linux as a whole, and I have no clue what's happening here.

I tried to install redis-server in order to integrate BLAST into my JBrowse install (program to search for nucleotide sequences, and a visual browser for displaying this data). When I used:

sudo apt-get install redis-server

The install hangs at 

Setting up redis-server (2:3.0.6-1ubuntu0.3) ...

after giving the program 2 days to run, I killed the thread by first using

ps aux | grep apt

Which gives

perryg    7954  0.0  0.0  14224   924 pts/7    S+   01:57   0:00 grep --color=au                                                                                                                                                             to apt

I used 

sudo kill 38577
sudo rm /var/lib/dpkg/lock
sudo dpkg --configure -a
sudo apt-get update
sudo apt-get autoremove

-or-

sudo apt-get install --fix-missing

and it always hangs at 

Setting up redis-server (2:3.0.6-1ubuntu0.3) ...

Any help is appreciated.

  • I am also experiencing this. I used strace to see what it was doing, its hanging in post-install. Still working on figuring it out – Cody Dec 19 '18 at 02:54
  • If I hear anything, I'll DM you ASAP. So far, no insight, and no resolution. I'm considering just using another node in the short term, and then probably just wipe the drive and start anew. – eng050599 Dec 20 '18 at 04:05
  • I'm having the same issue and also unable to remove redis-server due to it hanging. – Michael Lenzen Dec 20 '18 at 16:10
  • Michael Lenzen's solution below is a usable workaround until a proper solution is found. – Cody Dec 22 '18 at 00:02
  • Nope, Michael Lenzen's solution does not work for me: I don't have any init.d script, and after I purged redis*, I still cannot install redis... – xtof54 Jan 05 '20 at 10:21

My solution was to kill all redis-server processes, and try the remove again.

ps aux | grep redis

And use kill <pid> or kill -9 <pid>.

I had the same issue and it turns out I already had an Redis installed (not from apt) and running by default. I removed the init script for the non-packaged redis:

$ sudo mv /etc/init.d/redis_#### /usr/local/src/redis-stable/

Then when I restarted I could successfully install/remove the redis-server package.

  • This doesn't solve the issue in general, but functions as a work-around until the root cause is solved. This worked fine for me for now. – Cody Dec 22 '18 at 00:02
  • @Cody Being quite new to this, do you know what can cause this to reoccur, as the root issue hasn't been resolved? Also, are there any preventative steps that can be taken to prevent, or reduce it from happening? – eng050599 Dec 23 '18 at 03:12

Looks like it's a bug : https://github.com/antirez/redis/issues/3241

So the (temporary) solution is to edit /etc/redis/redis.conf and remove the '::1' in the line:

bind 127.0.0.1 ::1

After that, you can start redis with systemctl or service.
