Describe the bug
I use tar to extract item to /usr/ dir,and run xvncserver,it logs lots of dependency problem.I fix it one by one ,even sudo cp -r /usr/local/bin/KasmVNC /usr/share/perl5/vendor_perl/ and finally I got

syntax error at /usr/share/perl5/vendor_perl/KasmVNC/Utils.pm line 50, near ") {"
Execution of /usr/share/perl5/vendor_perl/KasmVNC/Utils.pm aborted due to compilation errors.

Apologies, our alpine support is not up to par. We added an Alpine option for KasmVNC largely to support Alpine based docker images.

See our alpine docker image to see how we implement.
https://github.com/kasmtech/workspaces-core-images/blob/develop/dockerfile-kasm-core-alpine

More specifically see the script that installs KasmVNC, there are two if blocks for alpine, the one at the end installs deps.
https://github.com/kasmtech/workspaces-core-images/blob/develop/src/ubuntu/install/kasm_vnc/install_kasm_vnc.sh

As for your current issue. Double check the dependencies based on the links provided. Given it runs, that seems unlikely, but you could have an incompatible version of a dependency.

I would try our alpine container directly and see if you can run and connect to it.

Here is the core Alpine image https://hub.docker.com/repository/docker/kasmweb/core-alpine-318/general
sudo docker run --rm -it --shm-size=512m -p 6901:6901 -e VNC_PW=password kasmweb/core-alpine-318:1.14.0

Then connect over https on port 6901, username kasm_user, password is password but you can change the pw in the command above.
