Both a queuefile and a package were found with the name "simple-scan".

simple-scan:

Would you like to continue processing the rest of the

queue or would you like to abort?  If this failed

package is a dependency of another package in the queue

then it may not make sense to continue.



(Y)es to continue, (N)o to abort, (R)etry the build?:
When i update version to 3.32.2.1 script builds fine and program works too, see the complete log:

https://hastebin.com/zoranodaga.bash

how to procede?

thanks!
