Installing deb files in Ubuntu 20.04 and 22.04įor some reasons, the default software to open the deb file has been set to Archive Manager tool in Ubuntu 20.04. The “fix” is simple, and I am going to show it to you in this quick tutorial. DEB files opened with Archive Manager instead of Software Center deb file for installing Rocket Chat messenger and when I double-clicked on it to install this software, the file was opened with the archive manager. I had upgraded to Ubuntu 20.04 from 19.10 and hadn’t faced this issue with it until today. You click on install, it asks for your password and within a few seconds/minute, the software is installed. All you have to do is to double-click the downloaded file and it opens (by default) with the Software Center program.

Usually this looks something like: apt-get source package apt-get source Approachįinally, you could use the apt-get source command to fetch the source of the package and configure it to install locally. This is a somewhat involved process, but one you should be able find community help for as many developers set up chroot environments for compiling code. schroot ApproachĪnother approach is to use schroot to create a non-root chroot. As long as all dependencies of the binary are installed, it should run as normal. Then you can export the PATH where the binary is. If the deb isn't in the Ubuntu repositories, apt-get package_name won't work, but you may be able to download it from a web site. deb Approach apt-get download package_name # replace `package_name` with the name of the package. Apt doesn't support it directly, but there are ways to do it.
