It takes a lot of time for unpacking packages (about 10 sec to 20 sec even for small packages), even after a new installation. I am using a Lenovo Ideapad 330.

I don't know whether it's a hardware problem or a software one.

My Ubuntu specs:

Half of the hard disk is empty.

Downloading is done in 15 mins but it takes about 3 to 4 hours for a system update. How can I check what is causing the problem?.

  • Please edit your question with the Ubuntu version you are using. Are you using the terminal to update or an application/program? What repository are you using? Also give some specs on your computer. RAM Processor Hard disk. Check how full your hard disk is. Ubuntu can run till nearly full but then it can't go as fast. Jun 28 '20 at 22:28
  • Do you get any errors or warnings? Have you checked top during an install?

  • No, no error. Its always the case. Jun 28 '20 at 22:33
  • What are you trying to install? It could be your internet connection

  • Just regular upgrade, no downloading is done in 15 mins, its installation that taking many hours. Aug 27 '20 at 19:04

It's most likely a slow hard drive. To figure out what component in your system is slow you can run hperf https://github.com/openlvc/hperf I've used it to find disk bottlenecks on VMWare servers.

When you are running it keep note of what suite causes a noticeable lag in the interface. You can then re-run any individual suites or tests suites to verify that area as the root cause.

Folks were mentioning using top. There are other "better" top like programs. I like htop but there is an even better one called "glances". This will give you a graph of disk/network/cpu IO with colors. https://github.com/nicolargo/glances

  • excellent suggestion ... I really like using glances for this kind of troubleshooting Sep 1 '20 at 21:31
  • I formated the system, it's working fine now. Sep 4 '20 at 10:01
