HI, Trying to install QCAD on a new Ubuntu 25.10 machine gives me this error:
zarg@zarg-Dell-G15-5530:~/Scaricati$ ./qcad-3.32.4-pro-linux-qt5.14-x86_64.run
Verifying archive integrity...Error in MD5 checksums: fe5d865b0953e88fb5c02b67d3e76eab is different from ea27b64d4038b49c46d4fc0fa098bdfd

Does anyone know why? I tested it on other PCs with Ubuntu 25.04 installed, and this does not happen.

Hi,

If the checksum of the downloaded package fails ... Have you tried to re-download the package?

Regards,
CVH

Yes, I did... many many times

Please check the MD5 checksum of the downloaded file:

$ md5sum qcad-3.32.4-pro-linux-qt5.14-x86_64.run
6f736d7a86c0c71ae03f133728670708 qcad-3.32.4-pro-linux-qt5.14-x86_64.run

If it doesn't match, your browser likely gives you the same cached file over and over again without redownloading. Clearing the browser cache should fix that.

So I tried ...
change browser ... failed
clear browser cache ...- failed
download, installed on different pc just to test it out, saved on USB and copy on ubuntu 25.10 ... failed

ciao
