No, certainly, my fault... I just did: $ zgrep "2020-07-23.*.install " /var/log/dpkg.log* | awk '{ print $4 }' | tr '\n' ' ' and then copied and pasted the output as argument of `# aptitude purge'... Just so simple. Now, I want to know when libiec61883-dev:i386 was installed into my system. To do so, I did: $ zgrep libiec61883-dev:i386 dpkg.log* dpkg.log:2020-07-23 08:07:12 status unpacked libiec61883-dev:i386 1.2.0-3 dpkg.log:2020-07-23 08:07:12 configure libiec61883-dev:i386 1.2.0-3 <none> dpkg.log:2020-07-23 08:07:12 status unpacked libiec61883-dev:i386 1.2.0-3 dpkg.log:2020-07-23 08:07:13 status half-configured libiec61883-dev:i386 1.2.0-3 dpkg.log:2020-07-23 08:07:13 status installed libiec61883-dev:i386 1.2.0-3 In the output there isn't any `install' item... How come...? thanks, rodolfo
