When installing the ThinLinc packages, the progress percentage goes above 100%. I have seen 130% followed by 200% at the end of the package installs on a RHEL8 system.
The relevant algorithm in installer/modules/thinlinc/rpm.py is:
> progress_cb(100*stage/stages + 100*hashes/50/stages)
Where 'stages' are number of packages and 'hashes' are the number of '#' characters per line in the output from rpm.
This means that when installing the last package the percentage will always exceed 100 when rpm output contains '#'.
