I don't use TS3 but I'll take a shot, seeing as 3.2.5 seems is the current version and is what is in the repository.
- Are you up to date
sudo eopkg up
- Are you're trying to update TS3 from within TS3. If so, don't do that, it's not how you update software on Solus or Linux in general.
I installed TS3, I don't get any errors.
