Changes the Debian (and relatives) install command to avoid warning

[pacharanero]

On my installation of Linux Mint 22.2 Cinnamon (X11) I encountered the following warning when using 'sudo apt install'

╰─$ sudo apt install ./espanso-debian-x11-amd64.deb

I don't fully understand the reason, but it is more usual to use sudo dkpg -i when installing a downloaded .deb from the local disk, and this is what I generally see in other software.

This PR simply changes the command to sudo dpkg -i. I have tested this on my machine by uninstalling the package that was originally installed by apt and reinstalling this way, and it seems to work without the warning.

Great work on espanso BTW - I look forward to using it!

Yup, this is the way I install a *.deb package.

@smeech has the final say though, he has a better overall view of the documentation

I'm inclined to stick with apt install rather than dkpg -i, I'm afraid, because it's what more users will be familiar with, and apt checks the package and automatically downloads and installs any missing dependencies, whereas dpkg -i doesn't.

Forgive me if I've misunderstood the problem, however!

[pacharanero]

It's of course up to you, but I've never seen the apt install file.deb command used to install a downloaded .deb archive before. It is always dpkg -i file.deb, and I presume that these warnings are the reason why.

apt is of course widely used to install packages by name from the repositories eg apt install <package>.

Thank you.

I think the furthest I'd go is to add a line that a N: Download is performed unsandboxed as root note can be safely ignored? I recall being a little bemused when I first encountered it, but was quickly reassured by a quick web search.
