Same issue here.
When I run SqlDeveloper with sudo, it gets installed and shown, but not without it.
When installing without sudo I get this error in terminal:

Installing updates...
Failed to backup /opt/sqldeveloper/sqldeveloper/extensions/keepalive.jar to /opt/sqldeveloper/sqldeveloper/extensions/keepalive.jar.backup.
Update installation failed.

Maybe not a good Idea, but doing this fixed the issue:

sudo chmod -R 777 /opt/sqldeveloper

The chmod tip worked.
But, I would just check the original owner, change to your user, and rollback the change
ls -ltrad /opt/sqldeveloper
(usually root)
sudo chown -R larry_e /opt/sqldeveloper
#start sqldeveloper with this user, install plugin, close the app.
chown -R root /opt/sqldeveloper

I didn't check if there is a file with another user inside sqldeveloper. But someone will do better than me and check.

Due to company regulations, I cannot run applications as an administrator. Since access rights to the user directories are probably the cause of the problem with the installation of keepalive, I have simply moved the SQL Developer user directory to another location.
I am using Windows 10 and SQL Developer 23.1.0.097, but it should also work under other Windows and SQL Developer versions.

My steps:

1. Unzip SQL Developer in directory c:\Users<username>\sqldeveloper\sqldeveloper-23.1.0.097.1607-x64\
2. Unzip Keepalive in c:\Users<username>\sqldeveloper_keepalive\unzip
3. Create a new directory c:\Users<username>\sqldeveloper_user_dir\
4. In case of migration, move contents from c:\Users<username>\AppData\Roaming\SQL Developer\ to the new directory c:\Users<username>\sqldeveloper_user_dir\
5. Add the following line to c:\Users<username>\sqldeveloper\sqldeveloper-23.1.0.097.1607-x64\sqldeveloper\bin\sqldeveloper.conf
   AddVMOption -Dide.user.dir=../../../_user_dir
6. Start SQL Developer and install keepalive via Update option just as usual
