I was performing an `apt upgrade` on a machine today and got the message: ``` **dpkg-deb:** **error:** <decompress> subprocess returned error exit status 2 **dpkg:** error processing archive /var/cache/apt/archives/linux-headers-5.4.0-181_5.4.0-181.201_all.deb (--unpack):  cannot copy extracted data for './usr/src/linux-headers-5.4.0-181/include/scsi/libiscsi.h' to '/usr/src/linux-headers-5.4.0-181/include/scsi/libiscsi.h.dpkg-new': unexpected end of file or stream ``` This was because the `.deb` file that was downloaded wasn't complete. To fix this I performed an ``` rm /var/cache/apt/archives/linux-headers-5.4.0-181_5.4.0-181.201_all.deb apt upgrade ``` and everything worked ok.
