I went from Windows 10 to Ubuntu. That is quite a positive difference.
UECIDE installed OK. One thing which gives a problem is "install library archive" in the "sketch" pulldown menu.
After selection of the library directory the message is: ... (is a directory).
Analyzing libraries . . .
And that is all which happens.
I did restrict the amount of libraries to the minimum.
Please have a look into this issue.
