How to install apt back after apt-transport-https uninstalled it

  • 772

I followed a suggestion and bricked my server. I no longer have apt / apt-get after installing apt-transport-https and I regret it.

I tried installing apt via dpkg but it errors out with:

dpkg: regarding apt_1.8.2.1_amd64.deb containing apt:
 apt breaks apt-transport-https (<< 1.5~alpha4~)
  apt-transport-https (version 1.4.10) is present and installed.

dpkg: error processing archive apt_1.8.2.1_amd64.deb (--install):
 installing apt would break apt-transport-https, and
 deconfiguration is not permitted (--auto-deconfigure might help)
Errors were encountered while processing:
 apt_1.8.2.1_amd64.deb

how do I uninstall apt-transport-https and revert back?

debian apt

    The version of apt-transport-https you have installed came from Debian 9, and the version of apt you propose to install is from Debian 11. Neither is appropriate for your Debian 10 system. apt-transport-https was deprecated in Debian 10 as its functionality is now included directly in apt.

    You both need to remove apt-transport-https and get the correct version of apt for Debian 10.

    You said that dpkg still works, so you should be able to use it to remove apt-transport-https. For example:

    dpkg --purge apt-transport-https

    After that you should be able to reinstall the correct apt package downloaded from debian.org as shown above.

    dpkg --install apt_1.8.2.1_amd64.deb

    Note that if you also deleted any of its dependencies, you will need to locate and install those first. An error message will tell you if this is necessary.
