How did you solve it?
Could you help me please?

@pggvngkt: Errors can appear similar, but still be quite different in cause. If you have an error post whatever log you have (if you hover your mouse over the upper right corner quote icon in one of your existing posts, then other icons will show up…the paper clip icon allows attaching files).

Download errors can be network errors, including proxy or firewall issues. A similar looking error might show up if your Ubuntu host is using a bad bzip2 update, but a checksum failure will be noted. If you see a checksum issue, then this may help:
