Hi, I found that a directory called Code: /var/cache/apt/archives# is taking up over 1GB. It appears to contain mostly olf versions of application libraries, which may have become obsolete through upgrades. Can I safely delete them? Please advise anyone. Here an extract of the directory Code: 5-snmp_5.2.4-2ubuntu5.1_i386.deb 12K php5-snmp_5.2.4-2ubuntu5.3_i386.deb 12K php5-snmp_5.2.4-2ubuntu5_i386.deb 12K php5-snmp_5.2.6-2ubuntu4_i386.deb 36K
