Problem

After updating from Scala 2.12.15 to 2.12.16 or 2.12.17, there is no more scala in /usr/bin/ or any other default bin path.

Is the same true for 2.13.x (currently 2.13.9)?

I wondered whether the root cause might be found in https://github.com/scala/scala or in https://github.com/scala/scala-dist

In the scala-dist repo, git diff v2.12.15 v2.12.16 shows nothing changing but the copyright year.

In scala/scala, I don't see anything in the output of the same command that seems like a likely culprit. 🤔

Is the same true for 2.13.x (currently 2.13.9)?

yum remove scala -y
scala -version # => file not found
yum install scala-2.12.15.rpm -y
scala -version # => Scala code runner version 2.12.15
wget https://downloads.lightbend.com/scala/2.13.9/scala-2.13.9.rpm
yum install scala-2.13.9.rpm -y
scala -version # => file not found

So, yes. Also missing in 2.13.9.

One moment: Looks like the problem only occurs on update!

yum remove scala -y
yum install scala-2.13.9.rpm -y
scala -version # => Scala code runner version 2.13.9

Looks like the problem only occurs on update.

Also true for 2.12.x:

yum remove scala -y
yum install scala-2.12.17.rpm -y
scala -version # => Scala code runner version 2.12.17

So maybe this is my fault? Is removal mandatory before updating?

However, this is not needed with the deb package on Ubuntu:

scala -version # => Scala code runner version 2.12.15
wget https://downloads.lightbend.com/scala/2.12.17/scala-2.12.17.deb
sudo dpkg -i scala-2.12.17.deb
scala -version # => Scala code runner version 2.12.17

I'm not able to account for the behavior you're observing.
