sed command to change dkpg database results in db corruption

[scottwilliambeasley]

It seems

sed -ri 's/(Package: libgcc1)/\1\nDescription: test\nMaintainer: test\nVersion: 2.19/' /var/lib/dpkg/status

needs to be updated. It appears to have corrupted the file /var/lib/dpkg/status

dpkg: error: parsing file '/var/lib/dpkg/status' near line 25 package 'libgcc1':
duplicate value for 'Maintainer' field

Adding the contents:

Package: gcc-8-base
Status: install ok installed
Priority: required

Description: GCC support library
 Shared version of the support library, a library of internal subroutines
 that GCC uses to overcome shortcomings of particular machines, or
 special needs for some langua

So I went in and removed the "official" Maintainer line.

Repeated:

dpkg: error: parsing file '/var/lib/dpkg/status' near line 29:
duplicate value for 'Version' field

Removed "Version: 1:8.3.0-6"

Repeated:

dpkg: error: parsing file '/var/lib/dpkg/status' near line 33 package 'libgcc1:amd64':
duplicate value for 'Description' field

So it seems the second sed command is not even needed

With all that, I am still getting the dependency problem from this line (which seems to be incorrect also).

pkg -i (location_of_multiarch) dpkg -i (location_of_libc6)

becomes

dpkg -i multiarch-support_2.28-10_amd64.deb dpkg -i libc6_2.28-10_amd64.deb

[ I have no name!@DFS]/sources
$ dpkg -i multiarch-support_2.28-10_amd64.deb dpkg -i libc6_2.28-10_amd64.deb
