i want to install a previous version of gcc (7.3.0). Currently, i have installed gcc in version 7.4.0.

I uninstalled gcc with sudo apt-get remove gcc; sudo apt-get autoremove and tried to install the previous version with

sudo apt-get install gcc=4:7.3.0-3ubuntu2

After installing it, the output ofgcc --version shows:

gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0
Copyright (C) 2017 Free Software Foundation, Inc.

So the installed version of gcc is still 7.4.0. Why does apt not install the specified version?

Thank you for ur help!

  • This version is not compatible. I got the package+version(gcc=4:7.3.0-3ubuntu2) while using sudo apt-cache policy gcc. Commented Jun 30, 2019 at 15:21
  • I got an error, because I did not install the additional required packages. This works now. Thank you for the help. My problem is fixed. Commented Jun 30, 2019 at 16:38

The gcc package is a metapackage which pulls in the appropriate compiler package; downgrading it won’t downgrade the compiler itself. You need to downgrade gcc-7, which is the appropriate compiler package in Ubuntu 18.04:

sudo apt install gcc-7=7.3.0-16ubuntu3

and any required package.
