Ok, originally my problem was rooted—I thought—in moving a site to a new hosting service. I tried various things. But before I posted this, I decided I would try it with a brand-new fresh install, and I get the same error message. So it can't be due to my old files which is what I thought was the problem.
When I try to install K2 I get
JInstaller: :Install: File does not exist /home/mxxx/public_html/xxx/tmp/install_5d59d98726f2e/components/com_k2/k2.php

[This was what I was first going to post.]
Originally, I moved all the folders and files and imported the database I exported from the old site.

There is an error message in the display area where K2 would appear on the main administrator page (An error has occurred.
0 Class 'K2HelperHTML' not found). I tried reinstalling K2, uninstalling, reinstalling. I tried fresh files and folders of Joomla and installing K2.
When I try to install I get
JInstaller: :Install: File does not exist /home/xx/public_html/xxx/tmp/install_5d59d98726f2e/components/com_k2/k2.php
Component Install: Failed to copy site files.

I also did a fresh install using Joomla 3.9.8 and get the same error message when trying to install K2.

As you can see here github.com/getk2/k2/tree/master/components/com_k2 the file /components/com_k2/k2.php does exist in the K2 package.

Perhaps the issue is related to file ownership permissions, that's why Joomla can't move the files around.

In case you have a load upload limit (1-2 MBs), try installing K2 using a URL (this github.com/getk2/k2/archive/master.zip to be exact).

If you use & love K2, please take a moment to add your review and rate it
at the Joomla Extensions Directory: extensions.joomla.org/extension/k2/

I increased the upload limit from 2 to 4 for something else. But I did try to install it from the web first using "install from web" and then I tried to upload the package with the same result.

What can I do to find out if the permissions issue? The tmp folder is 755.

Thanks you.

The issue may be related to "ownership" permissions. These can only be corrected by your hosting provider if you use shared hosting.

I contacted the hosting support, and they tried to install K2, and ended up doing it by uploading a package, but still got error messages. They are asking me to ask you what server side adjustments need to be made. here is their message:

I am was checking the issue for the last few hours. We could see that the K2 installation shows successful when we do via the admin > Extension > Manage > Install > Upload package

We used K2_v2.9.0.

But still, the issue you have mentioned is present under the website.

Following is the error we get on the log file.

[23-Aug-2019 14:50:46 UTC] PHP Notice: Use of undefined constant K2_JVERSION - assumed 'K2_JVERSION' in /home/missouri/public_html/16juliadentgrant/administrator/modules/mod_k2_stats/mod_k2_stats.php on line 15

Also, the Class 'JPane' not found issue indicates to the templates issue. Is it possible to have a check with your developer and let us know if any server-side adjustment is needed?

The JPane error he refers to is found in the administrator landing page where K2 components are usually listed. See screenshot attached. Thank you.

JPane is part of Joomla. The warning you get for K2_JVERSION indicates the K2 system plugin is not loaded.

This means not only K2 but Joomla itself may not be functioning properly. If your webhost has no idea how to solve a file ownership/permissions issue, then you should seriously consider changing hosts.

If however the issue is resolved (with file ownership/permissions), you can re-install Joomla from the Joomla update option and K2 from the extension installer.

The solution "wasn't as simple as file permissions." The hosting company was able to determine that the problem lay with the "handler." The server using the FCGI handler would not install K2, but the server using ISAPI did. They moved my site to to the server with the ISAPI handler, and now all is right with the world.

Actually, that's a bogus claim. FCGI (for FastCGI) and LSAPI (as it is, not ISAPI) are just ways to run PHP on Apache (called PHP handlers).

The problem stems 100% from wrong file ownership permissions though, which they should know how to correct (it's not rocket science either way).

What actually happened was that WHEN they switched the PHP handler for your account, the control panel running on the server (assumingly cPanel) corrected the file ownership issues automatically, because different PHP handlers (e.g. DSO vs FastCGI/CGI/suPHP) require different permissions set.
