Thanks, finally! Just installed it on Ubuntu 18.04 without any major problems. No scaling or segfaults like others.
The only thing I noticed: The option "Autofill if only one item applies" does not work. I always have to click the one item, which is kind of annoying.
//edit:
@Anshu kumar Can you say when approx. the portable version of Enpass Beta for Windows will be released? To fully test and use the beta, I have to use it on my work PC also, where only portable version is working.
