Pass: The standard Unix password manager
A well praised password manager that unfortunately will never be useful for the non-tech people, at least for me. I saw so many  wonderful reviews, recommendations and reports about the simplicity of using it. And the level of excitement from the reviewers made me think I should try it as soon as possible. But with only basic-medium Linux skills I will never be able to install pass. I looked everywhere for step by step tutorials on how to run it, but there‘s always a „skipped“ step or a small „something“ that will lead me to failure (despite of spending hours in searching how to do this part). Unfortunately I had to give it up and started to use bitwarden.
Same with etesync - no way to use it, even the paid version with hosting on the developer‘s server gave me a hard time. I could never use it right: android, iphone or macos. So back to Apple‘s calendar or some other easy alternative.
Ah… :-(
