Installing issue on Ub 18.04

Asked by ketan

HI,

I am using ub 18.04

when i perform repo installation i am been prompted teh following

There are services installed on your system which need to be restarted when 01:21:29 certain libraries, such as libpam, libc, and libssl, are upgraded. Since these 01:21:29 restarts may cause interruptions of service for the system, you will normally 01:21:29 be prompted on each upgrade for the list of services you wish to restart. You 01:21:29 can choose this option to avoid being prompted; instead, all necessary restarts 01:21:29 will be done for you automatically so you can avoid being asked questions on 01:21:29 each library upgrade. 01:21:29 Cancelling nested steps due to timeout 05:30:09 Restart services during package upgrades without asking? [yes/no] Sending interrupt signal to process 05:30:29 After 20s process did not stop

I have the following questions

1. why is this prompted ?
2. is this prompted only for 18.04 or does it happen on 16.04 as well as 19.04 ?
3. how to fix this ?

What does the system do and is the outage at 1:21am acceptable?

is this prompted only for 18.04 or does it happen on 16.04 as well as 19.04:
There is a related question https://unix.stackexchange.com/q/146283 dating back to the year 2014. This let me assume, that this question sometimes was asked also on older releases than Ubuntu 18.04, and most probably ist there also on all other Ubuntu releases including 19.04

why is this prompted:
If you are running a server that should be available 24/7, then you have to decide what to do when installing updates. You can either postpone restarting the services that use certain updated libraries (with the consequence that the updates are not completely installed), or you can restart the services (with the consequence of a short interruption). The package management system cannot know what choice you have to take in your situation with your system and asks what to do.

how to fix this:
There is nothing to fix. Just answer yes or no, with the consequences as described above.

Don't you do scheduled patching when the impact is least and agreed upon by customers and so on....? I'd never just randomly update a server in any OS without agreed scheduling or a change request if the update resolves an issue....

Can you help with this problem?
