I tried to install some .deb
files in Ubuntu 20.04 from GitHub and other internet sources, but when I open it with Software Install it gives me this problem (Failed to install file: not supported). The only way for me to install them is to go to the downloaded file and do sudo dpkg -i file.deb
.
Can anyone help? I don't know what to do and I don't want to use the terminal every time.
Any help would be appreciated, thanks
EDIT: that's NOT a problem with .deb in Ubuntu, it is a problem with Software install. I can install every .deb through the terminal but not with Software install, and Ubuntu suggests to install .deb with Software install. That's not a dependencies problem or anything similar, that's an issue with installing .deb WITH Software install and I would like to know how I can fix Software installer
sudo apt install ./my_filename.deb
thandpkg
directly. That way it can do dependency resolution etc. properly, whichdpkg
does not. Note you need an absolute or explicit relative (i.e. starting with./
) path forapt
, so that it can distinguish if it is a file or a package name.
