Hi Would you be able to help me with what is probably a really basic problem, with installing and then starting OpenConnect? I have rebuilt my PC and moved across to Linux from Windows 10. Although I grew up in the 70's and 80's and learnt to programme using BASIC, it is not something I have since had to do, but am capable in understanding direction [I am a civil engineer]. I am working my way slowly through problems, but can not resolve the problem of installing or starting OpenConnect [as a replacement to a Cisco AnyConnect VPN I had on my Windows PC]. I have downloaded and extracted the files, but have reached a point where I am now stuck and can not seem to move forward, and would really appreciate your help, as I do not properly understand the next steps. Many thanks Philip Below is the complete script so far. To run a command as administrator (user "root"), use "sudo <command>". See "man sudo_root" for details. philip at philip-550-254na:~$ cd ~/Downloads philip at philip-550-254na:~/Downloads$ openconnect-7.08/ bash: openconnect-7.08/: No such file or directory philip at
