Hi @zzappa
Unfortunately, the i686 version of the Linux client was removed in 4.15.0. Most major Linux distros have now abandoned support for 32-bit x86 silicon. Therefore, we decided that the maintenance cost outweighed the benefit.
We understand that this is bad news for you. But I’m afraid you will have to continue using the 4.14.0 version of the client. ThinLinc 4.14.0 will continue to be supported until 2025-02-07. I recommend that you disable the “Check for client updates” setting.
You can find older client versions on this page:
