'apt search` cannot find packaged not already installed; 'sudo apt install' cannot install new packages

Asked by Haoyang Wang on 2017-12-05

'apt search` cannot find packaged not already installed. 'sudo apt install' cannot install new packages. For example, I tried to install 'qt5-default', and got:

haoyang@USD699:~$ apt search qt5-default
Sorting... Done
Full Text Search... Done
haoyang@USD699:~$ sudo apt install qt5-default
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package qt5-default

Thank you!

Here is my diagnostic outputs on Terminal:

What is the output of:

apt-cache policy qt5-default

Thanks

Haoyang Wang (wanghaoyang) said : #2

haoyang@USD699:~$ apt-cache policy qt5-default
N: Unable to locate package qt5-default

According to:
https://packages.ubuntu.com/search?keywords=qt5-default&searchon=names&suite=xenial&section=all

It's in the universe repository. Use your GUI application installer and make sure this is enabled.

Best Manfred Hampl (m-hampl) said : #4

You have errors in the sources.list configuration files.

The binary packages for arm64 architecture are not available on the same repository servers as the i386 and amd64 packages, but only on the ports.ubuntu.com server.

Do you really need binaries for arm64 architecture?

If no, then you should remove arm64 as foreign architecture with the command
sudo dpkg --remove-architecture arm64

If you need that additional architecture (e.g. because of doing cross-compilation), you have to reorganize your sources.list files and separate the lines for i386 and amd64 from those for arm64, something like

deb [arch=amd64,i386] http://archive.ubuntu.com/ubuntu/ xenial main universe
deb [arch=arm64] http://ports.ubuntu.com/ubuntu-ports xenial main universe

In any case you have to make sure that the command "sudo apt-get update" does not show any error message (like 404 Not found) any more.

Haoyang Wang (wanghaoyang) said : #5

Yes, after adding the architecture notations (like [arch=amd64,i386]) in sources.list, sudo apt update now works without errors and the system is back functional again.

Thank you for your help in solving the problem so fast! Thanks again.

Thanks Manfred Hampl, that solved my question.
