Unable to install protonmail bridge due to missing dependencies about zypper HOT 2 CLOSED

If you type rpm -ivh protonmail-bridge-3.0.19-1.x86_64.rpm you are using rpm not zypper. rpm does not know anything about repositories. It just sees what's offered on the comandline.
Try zypper in protonmail-bridge-3.0.19-1.x86_64.rpm

from zypper.

Protonmail bridge is not available with zypper

zypper depends on the repositories you have added and enabled on your system (see them with `zypper lr). They advertise the rpm package zypper is able to download and install.

If protonmail-bridge is not advertised in your repos you may manually download and install the package (see above). If you find a repository that offers protonmail-bridge for your distribution, you can add it (see zypper ar ...) and to install the package by name (zypper in protonmail-bridge). You can visit e.g. https://software.opensuse.org/ or https://build.opensuse.org/ to search for packages in distribution or user repositories.

Zypper uses repositories, but has no influence on their content. If you think protonmail-bridge should be added to the distribution you are using, you should raise the topic e.g. on the distributions mailinglist.
