I found an error when updating the version to Debian 10
dpkg-deb: error: archive "/var/cache/apt/archives/tinycp_2.252.0_all.deb" uses unknown compression method for "control.tar.zst", stop dpkg: error processing archive /var/cache/apt/archives/tinycp_2.252.0_all.deb (--unpack): dpkg-deb --control subprocess returned error exit status 2 Errors occurred while processing the following packages: /var/cache/apt/archives/tinycp_2.252.0_all.deb E: Sub-process /usr/bin/dpkg returned an error code (1)
The latest version of the zstd package is installed (judging by the Debian 10 archives)
But there is a solution:
cd /var/cache/apt/archives
ar x tinycp_2.252.0_all.deb
mkdir control_dir
tar -xf control.tar -C control_dir
tar -czf control.tar.gz -C control_dir .
mkdir data_dir
tar -xf data.tar -C data_dir
tar -czf data.tar.gz -C data_dir .
ar rcs tinycp_2.252.0_all_new.deb debian-binary control.tar.gz data.tar.gz
sudo dpkg -i tinycp_2.252.0_all_new.deb
Проблема решена.
